Inside the train, Isa was looking at the mirror as she was deep in thought.

*Flashback*

Azazel: Isa, your Sacred Gear holds the feelings of all the previous Red Dragon Emperors before you. Their negative feelings are very strong. You can pretty much call it a curse. If you can purge those negative feelings, I believe you can pull up something safely and as powerful as the Juggernaut Drive. In order to do that, you must inject your conciousness into your Sacred Gear.

*Flashback*

Isa was meditating on her bed as she then appears in a blank space with a large group of cloaked people in front of her.

Isa: Hello?

She then looks closer as the people with cloaks looked dead inside.

Isa: Um, excuse me?

She waves at one of them but he dosen't respond.

Isa: Can you hear me?

She then backs off with a sigh.

Isa: It's no use. No matter how many tries I try, there's no progress.

*Flashback End*

As she was deep in thought, Y/N taps her shoulder with a smile.

Y/N: You okay?

Isa: Oh, yeah.

After that, they went back to their seats.

Y/N: What were you thinking about?

Isa: I was just thinking about what Azazel had told me.

Y/N: You mean about the negative emotions?

Isa: Yeah.

Y/N: Don't worry. I'm sure you can do it.

Isa: *smiles* Thanks.

Y/N: Oh, I also heard that Xenovia, left Durandal with the Church for some upgrades.

Isa: Really? Then I will let her use Ascalon.

They then see Yuri walking to them.

Yuri: Hey, can I sit here?

Y/N: Go ahead.

She sits down in the sit and smiles.

Yuri: Just in case something goes wrong, I wanted to ask you about your plans when we get there.

Y/N: We're going to start at Kiyomizu Temple...

He then hands Yuri a flier.

Yuri: I'll also be in Tenryuji on the third day. If we plan it right, we may be vale to meet at Togestukyo bridge. By the way, Isa.

Isa: Yeah?

Yuri: Before Y/N's battle with Sairaorg, I heard that you had to deal with the four Great Devils.

Isa: Yeah. That was a very fierce event. It completely changed my image of the underworld. The four great devils, dressed as hero rangers, kept doling out trials. Well, I managed yo pass them all, but...

*Flashback*

Isa was in front of Ajuka as he was taking the pawn piece inside her.

Ajuka: This is just an opportunity. Right now, you are finally in front of many doors with one key in hand.

*Flashback end*

Isa: Come think of it, I got some advice from Lord Beelzebub, too.

Y/N: Advise?

Isa: Yeah. To maximize the power of the Welsh Dragon, I need to master being a knight and a rook. Since Sairaorg told me he also wanted to fight me, I don't think I have a chance right now.

Yuri: Yes, you're right. Right now, we're far too weak...

Isa: I'll have to during our trip, too!

Yuri: As expected from you.

Yuri then stands up.

Yuri: Well, contact me when you are buying souvenirs. I don't want to accidentally buy the same thing.

Y/N: Sure. Let's meet again during the trip.

He says with a warm smile as Yuri's face turns slightly red.

Yuri: Y-Yeah, I'm sure de will.

She then walks away.

Isa: *mumbles* We still have time.

She then closes her eyes as it seemed she went asleep.

Y/N: She must be tired.

Y/N then felt his eyes getting heavy.

Y/N: What...?

His eyes close and after a few moments he opens them and noticed he is in the Velvet Room.

Y/N: Is something wrong?

Lavenza: None at all. You're actually doing quite well.

Igor: I have called you because you have a guest that's been meaning to meet you.

Y/N: Someone who wants to meet me?

Igor: Yes. As you know it is rare for a user of the Spirit of Rebellion to appear, for instance there haven't been many through history, the one who wants to meet you is your predecessor.

Y/N: My predecessor?

Igor: Yes. In fact he should be arriving any moment now.

As if on cue a suddenl light appear from the other side of Y/N's cell as when it dissapeared a grayish haired guy with a black jacket and a pair of glasses appear.

(So I didn't play Persona 4, but I think I know a little about his personality, but not all)

???: Huh, so you're my succesor. It is nice to meet you, Y/N L/N.

Y/N: Nice to meet you, too. But what is your name?

Yu: My name is Yu Narukami. Although, I must say, this is not what expected from your version of the Velvet Room.

Y/N: My version...?

Igor: The Velvet Room changes depending on the user's heart.

Yu: Yeah, it is never the same. I don't blame you, though. I didn't knew that either until I met my predecessor.

Y/N: Wait, how many Spirits of Rebellion have been through history?

Igor: There have been many of them, but there have only been five that have the potencial to unlock the infinite power it contains.

Yu: Two of those five is you and me.

Y/N: Only five?

Yu: Yes. Although, even between us five, we have our own ranks.

Y/N: Ranks?

Yu: Yeah, I am the second strongest. And I would guess you're the weakest of us five, right now.
(According to google, he is the weakest protagonist, but since I literally know nothing about Persona 1 or 2, he will be the second strongest)

Y/N: The weakest...?

Yu: Yeah.

Y/N: Then who is the strongest?

Yu: Well, that would be my predecessor, but he's not the most social person you might find.

Y/N:I see. Why did you want to meet me?

Yu: Just pure curiosity. I wanted to meet my succesor.

Y/N: I see.

Yu: Also, I heard you broke a contract with your Persona. I must say, I'm impressed you're still alive.

Y/N: Is it really that rare?

Yu: Rare? *chuckles* It was thought to be impossible. You're the first to survive it.

Y/N: I see... Wait, you said that you're the second strongest, but isn't the Spirit of Rebellion supposed to have infinite power?

Yu: Yes. But that dosen't mean we all have the same strength.

Y/N: Oh...

A bright light then started to appear.

Yu: It seems we're out of time. I'm looking forward to our next meeting, Y/N L/N.

The light covers the room as and in a flash Y/N's conciousness is back in the train.

Y/N: Yu, huh.

He looks to his side and see Isa laying her head on his shoulder, and he smiles.

Suddenly she opens her eyes and looks confused.

Isa: Huh? I'm back.

She then looks at her hands.

Isa: What happened to the box?

Y/N: Box? What are you talking about?

Isa: My potencial!

Y/N: Okay...

Isa then explains him that she met the second strongest Red Dragon Emperor, who was a woman like her, and she gave Isa a box that supposedly held her own potencial.

Y/N: I see. Something similar happened to me.

Isa: Really?

Y/N: Yeah. I met my predecessor.

*Timeskip*

They had finally arrived at Kyoto as they were standing at the train station.

Aika: All right, guys. Enough standing in awe. Everyone has already gone ahead.

*Timeskip*

Matsuda: Oh, yeah! We get to stay at a place like this?!

He says amazed by the inside of the hotel they were staying.

Matohama: I can't believe it.

Aika: Okay, okay. Hurry up and go in. You guys are blocking traffic.

They walk forward as they find Rossweisse and Azazel.

Azazel: Hey, guys. Your teacher Miss Rossweisse has some warnings for you guys.

Rossweisse: The... one hundred yen shop at Kyoto station! It is located in the underground shopping center!

Azazel: Okay. That's all from Miss Rossweisse.

He says as Rossweisse keeps talking.

Azazel: Please go to your individual rooms now.

*Mini Timeskip*

Y/N opens the door of his room as he stands confused due to his room being a Japanese style.

Y/N: Is this really my room...?

Suddenlly, Matsuda and Matohama appear in the door laughing.

Matsuda: Seriously?! This is the only Japanese style room!

Y/N: What are you doing here?! Wait, the only one?!

They then show him a picture of their rooms which were more modern.

Matsuda: Guess this is how they were able to manage to pay the lodging budget.

Rossweisse: Y/N, are you here?

Rossweisse then appears at the door as Y/N walks to her and whispers.

Y/N: Why is my room like this?

Rossweisse: This is a room that Rias prepared for us. She prepared a place where we can gather and talk in emergencies.

Y/N: I see. But why my room?

Rossweisse: *smiles* Please live with it, Y/N.

She then turns to the other two.

Rossweisse: Well, everyone. The afternoon is free time, but make sure not to go too crazy.

Matohama and Matsuda: Yes!

Rossweisse then walks away.

Matsuda: What should we do?

Y/N: We?

Matsuda: Well, yeah! We're on the same group!

Matohama: Besides, we have a senior with us!

Y/N: If you even touch Akechi, you can consider yourselves death.

Matohama and Matsuda: *afraid* Okay!

Matsuda: You don't have to be harsh!

*Timeskip*

In the end, they were at a market as Irina, Xenovia, Asia, Isa, Akechi and Aika went with them.

Asia: Wow, there's a lot of adorable foxes. I wish we could take them home.

She says while watching some of the figures on the stands.

Irina: They're really cute! Let's show Xenovia, too!

Asia: Yes!

Irina: Xenovia!

She calls to Xenovia who was looking at a wooden sword.

Irina: Look! Look! They're so cute!

Xenovia: Yeah! It's cute.

After some time they were now at the entrance of a shrine as they looked at a statue that looked like a fox.

Xenovia: So this is a statue that keeps demons away. Normally, it excludes a power that won't let us get close... But it looks like it won't be a problem with the pass.

They continue walking as Y/N stlod looking to the side as he thought he saw something.

Matsuda: Hey, Y/N! You're slow! Hurry it up!

Matohama: But make sure not to enter the camera's view!

Y/N: I still don't understand why you two came with us in the first place...

They continue walking as they were now crossing a path that had a lot of gates.

Isa: As expected of the thousand gates. No matter how far you walk, the Torii gates just keep going.

Akechi: This is still the entrance. We have to pass through all this gates and climb up the mountain to reach the top.

Matohama: Seriously?

After some more time they kept walking as Y/N heard some movement from the bushes and saw that Akechi heard them as well, as she narrowed her eyes.

Isa: Sorry, I'm going ahead.

She then sprints off and after a few minutes she arrives at shrine as she starts to pray.

Isa: *whisper* I hope Y/N confesses to me one day.

Y/N: So this is the top, huh?

Isa yelps a little as she turns around and see Y/N.

Y/N: You were praying?

Isa: Y-Yeah.

???: You two are not from Tokyo.

Suddenly they were surrounded by a group of people with masks and a girl with fox traits stood at the top of the shrine with two crow like men by her sides.

Y/N: A Kitsune?

Kitsune girl: Outsiders! How dare you. I will have you return my mother!

Y/N and Isa: Huh?

Isa: What are you talking about?! We don't know your mom!

Kitsune girl: Don't lie! You cannot deceive my eyes!

One of the crows charges with a spear as Y/N and Isa dodge the attack with Y/N transforming inmediately after.

The two of them then jump out towards the forest as they kept dodging every attack.

Y/N dodge one of the attack by jumping but when he landed one of the crows was already in front of him, but before it could strike, Xenovia and Irina blocked the attack with their swords, except for Xenovia who was using the wooden sword she bought.

Xenovia: Are you two okay?

Then Asia and Akechi, who was already transformed, arrived at the place.

Kitsune girl: Impure existences of evil! I will never forgive you!

Akechi: Ohh, a nest of weak but pesky vermin.

Isa: Asia! The substitude acknowledgement card!

Asia: Yes!

Asia then takes out a card with a golden spot and pointed it at Isa.

Isa: All right! Promotion, knight!

Isa then summons her Boosted Gear.

Kitsune girl: Attack!

Y/N: We're not on devil territory! Try to cause as minimum damage as you can!

Everyone: Roger!

Everyone started fighting and Y/N who had three enemies in front of him is then joined by Akechi at his side.

Akechi: Wouldn't be much easier if we kill them?

Y/N: Yeah, but we're not here to cause a war.

Akechi: Fine, then.

Y/N and Akechi: Arsene!/Loki!

The two summoned their Persona and with a combined curse attack they pushed back the three enemies.

The enemies started to fall back as they regrouped.

Kitsune girl: R-Retreat! You evil existences! I will have you bring back my mother!

A tornado then surrounded them as the enemy dissapear along with the tornado.

Isa: What was that about?

*Timeskip*

Y/N was inside the hotel with Azazel and Rossweisse as he told them what happened.

Azazel: Why were you attacked in Tokyo?

Y/N: I want to know that myself.

Azazel: I see. Go back to your room. I'll take care of how to report it.

Y/N: I understand.

After that Y/N was laying on his bed as he was still awake.

Since he couldn't sleep at all he decided to take a bath to relax his body.

Unknown to him, there was a devilish perverted devil walking through the stairs, heading to Y/N's room.

Isa then stoped on her track as she saw Rossweisse in front of her.

Rossweisse: As a teacher... I will protect the body of my precious student with my life!

Isa: Even if we're allies, this is one thing I cannot back down on!

She then summons the Boosted Gear.

Isa: I am foing to sneak a peek on Y/N!

Rossweisse: Then, it cannot be helped.

With a battle cry, Rossweisse sends a magic blast towards Isa as she responded with her own, and the two attacks collided.

Rossweisse: Your attacks are stronger than normal!

Isa: Rossweisse, if I can see the naked body of the man I love, I don't mind dying on my sword against you!

Rossweisse: Hasen't he kissed you already! That should be enough!

Isa: That's that! This is this!

Rossweisse: *sighs* This is my last resort, but I can ask Saji to stop you. I'll have him transform into his Dragon King form.

Isa: S-Saji?! You'd go that far... Come on! I know you also want to see him!

Rossweisse's face became red as she imagined Y/N's body, shirtless, but inmediately regained her composture.

Rossweisse: T-That's not true! He's my student! I cannot do that!

Isa: Cut me some slack! If you have such a small heart, you'll never get a boyfriend!

At this Rossweisse became embarassed and upset by hearing Isa's words.

Rossweisse: B-B-B-B-Boyfriends have nothing to do with this! I-I-I-I'm just an ex-Valkirie virgin! I want to do perverted things with a boyfriend that has a bright future, too!

She then released a powerful aura as Isa looked a little nervous.

Isa: This is bad! I pushed a weird button!

Rossweisse then gave Isa a scary look.

Rossweisse: I will no longer forgive you.

She says while charging a thunder attack on her hand.

Isa: If it's come to this...

Rossweisse then fires the attack as Isa dodges while closing the distance between them and boosting herself at the same time.

Isa: *thoughts* I've never used this technique in battle, but it should guarantee my win!

Isa suddenly dissapears as Rossweisse eyes widen, and appears behind her.

Isa: Tear apart!

She then places her hand on Rossweisse back.

Isa: Dress Break!

Suddenly all of Rossweisse clothes tored apart as she was left naked.

Isa: It works! Now I can use it on Y/N!

Rossweisse then glared at her while trying to cover her breast.

Isa: Oh... S-Sorry, I ended up going too far.

Rossweisse: This jersey was on special sale! It was 980 yen!

Isa: Huh? You're mad about that?!

Rossweisse: It was cheap, but cute and I really liked it!

Suddenly she barely realizes she is naked at the hallway and her face turns embarassed.

Rossweisse: Oh, no! If Y/N sees me, I won't be able to get married!

Isa: So slow on the uptake...

Rossweisse: Leave me alone! To begin with, it's bad to rip up clothes! It's bad for enviroment, too! As your teacher, I can't just forgive you!

Back at Kuoh, Rias, Akeno, Koneko and Sumire were at the baths as Akeno stared at Rias.

Rias: Is something wrong, Akeno?

Akeno: I wonder what kind of boobs Y/N likes.

Rias: Huh?

Akeno: Could it be bigger?

Rias: If that would be the case he would like yours more. Right, Koneko?

Koneko: I really don't see a diference.

Rias: How about you, Sumire?

Sumire: I-I don't really know what to say about it.

Koneko: Perhaps Akeno's are slightly larger.

Akeno: Oh, is that so?

Akeno then moves towards Rias and gropes her breast as Rias yelps.

Akeno: How about the shape?

Rias: Hey, Akeno?!

Akeno: Or the softness?

Rias: Now, stop it. Hey!

Akenk: I wonder how the left one is?

Rias: *moans* You're squeezing my left harder than the other!

Akeno: *giggles* I'm sure Y/N likes mine better.

Rias: That's not true, Y/N likes mine better!

As they continued fighting, Sumire looked at them confused as Koneko kept a stoic face.

Sumire: Are they always like this...?

Koneko: You get used to it.

Rias: Goodness, Akeno!

Akeno: Rias, you get adamant so easily.

Rias then frowns.

Rias: *thoughts* I can't believe there's still two whole days until Y/N comes home.

Back in Kyoto Isa and Rossweisse were at Y/N's room since it was the closest they were at, and he gave her his jacket and some sport pants. And Rossweisse was scolding Isa.

Rossweisse: Your sexual desire is too strong! Are you even listening?!

As she was scolding her, Isa has an upset look as Y/N had finished his shower before they arrived.

Y/N: I believe you went too far this time, Isa.

Isa: It was for a good cause!

Y/N: Since when is peaking at someone a good cause...?

Azazel: I'm coming in.

They hear Azazel's voice from outside, and then the door opened to reveal him.

Isa: Azazel!

Azazel: Sorry for interrupting your fun.

Rossweisse: *blushing* Y-You're wrong!

Isa: *pouts* I wish it was like that!

Y/N: Why are you here, Azazel?

Azazel: Our little Great Devil Queen is calling for all of us to gather.

After that, The ORC along with Y/N and Akechi reunited with the second years of the Student Council and Serafall who was wearing a Japanese yukata, in a room with a table filled with food.

Saji: Oh, Y/N.

Y/N: Hey, Saji. How has Kyoto been for you?

Saji: I'm part of the Student Council. I was helping the teachers and didn't get a chance to anywhere.

Akechi: I can relate. I was forced to come and take care of them.

Serafall: The poultry, here is exceptional! Eat up, everyone!

Y/N: I'd like to ask, why are you her, Serafall?

Serafall: For work. I came to forge an alliance with the youkai of Kyoto. It's just, something terrible has happened.

Yuri: Something terrible?

Serafall: The leader of the Kyoto youkai, a nine tailed who kept them together, has gone missing.

Y/N: Then, that would mean the attack at the shrine...

Saji: Oh, it seems that things were pretty tough for you, too.

Serafall: I heard your report from Azazel. I believe it to be the case.

Azazel: The ones behind it are probably...

Serafall: The Chaos Brigade.

Y/N: Yeah, I thought the same.

Azazel: Damn, our hands are full taking care of the students right now! They really got us this time.

Serafall: There are youkai that ar w willing to help us in Kyoto. We plan to help them throthose contracts.

Azazel: I'll move as well.

Y/N: What about us?

Azazel: For now, enjoy the trip.

Y/N: Wouldn't be better if-

Azazel: I'll call for you if something happens. For brats like you, aren't class trips important memories? We adults will do what we can so enjoy Kyoto for now.

Serafall: That's right, make sure to enjoy Kyoto to the fullest! I plan to do the same!

Y/N: *chuckles* You're right.

He then gives a bright smile as Serafall blushes, but she makes it dissapear before Y/N notices.

Serafall: Bow, let's enjoy the food!

Isa: For now, we can only fill our bellies! Well, then!

Everyone: Thanks for the food!

Y/N and Akechi along with the ORC were currently walking through the streets of Kyoto.

Y/N: People who wish to break the current system, the Chaos Brigade. It isn't only made up by the Old Satan faction.

Isa: There are others, too.

Xenovia: Looks like things are more serious than we thought.

Yuri: Yes, that is indeed correct.

Akechi: We should prepare for the worst case scenario.

Asia: Yes, even if big sister Rias isn't here...

Y/N: *thoughts* I will protect the city of Kyoto that she loves so much.
