Saturday afternoon
Kuoh City park

Taking a quick peek at his watch, Kiba wondered if he was too early to his date with Akeno. He checked his outfit again to make sure it was neatly kept. A voice pulled him out of his inspection.

Akeno:"Good afternoon, Kiba!"

Kiba:"Akeno, good afternoon! You look beautiful."

Akeno:"Fufu~, why thank you! My mother and Raynare helped picked out my clothes. What have you planned out for our outing?"

Kiba:"A few things here and there, if you don't mind me keeping it a surprise."

Akeno:"Of course."

Kiba:"Then, shall we?" Holding out his arm to let her hold on, an act befitting of Kiba.

Akeno:"Mhm!"

From a distance, Akihito watched on the two love birds. Wanting to be sure of his little sister's safety, he followed her until she meet up with Kiba. Satisfied with their meeting, Akihito returned back home.

Akihito:"I'm home!"

Raynare appeared from around the corner, welcoming him back and questioning the date.

Raynare:"How did it go?"

Akihito:"I would say it went well. I'm not going to intrude on them any longer than need be so I left."

Raynare:"That's good, well anyway, Rias came by. She's been waiting in the living room for quite some time."

Akihito:"I'll speak with her."

Akihito took off his shoes and followed Raynare into the living room. There, he found his parents and Rias chatting it up.

Rias:"Akihito doesn't hold you in contempt?"

Baraqiel:"Thankfully he does not and neither does Akeno. I've been let go by Azazel not long ago. I've served him for a good while now, he said that it's best to enjoy the time I have with my family."

Rias:"I never would have thought Azazel could be so caring."

Akihito:"You guys done?"

Shuri:"Aki! Come sit down, we were talking to your friend about your father."

Akihito:"So, what is it you need now?"

Rias:"As Akeno's brother, it would only be right to invite you to the Devil Realm. Knowing what the occasion is already, you should expect young Devil Lords to be asking Akeno's hand in marriage."

Akihito:"Why?"

Rias:"To get close to the 'Dark Lord', of course. Many families in the Devil Realm would certainly wish to have you on their side so this conference is more than the perfect opportunity for that chance."

Baraqiel:"They will do no such thing! Those Devil bastards thinking of my little girl as nothing more than an object is infuriating!"

Shuri:"Dear, calm down."

Rias:"I understand your anger which is why I came here to warn you. My family received word of this from the Phoenix Clan."

Akihito:"Phoenix?"

Rias:"After Riser's death, they wished to not be apart of this fiasco."

Shuri:"Aki?"

Akihito:"Yes?"

Shuri:"You will go with Akeno and crush their measly souls right?" She gave off a radiant smile but behind that smile was pure fury.

Akihito:"You have my word, mom. When do we leave?"

Rias:"Tomorrow in the morning."

Akihito:"Alright."

Rias:"That was all I had to pass on, I'll be taking my leave now. Thank you for the hospitality, Mrs.Himejima."

Shuri:"Of course, Rias. Let Akihito take you to the door."

When Rias finished wrapping things up with the family, she went to the front door. As she put on her shoes and opened the door, Akihito stopped her.

Akihito:"Wait."

Rias:"Yes?"

Akihito:"I...um...wanted to thank you for the heads-up. I know I had butt heads with you a ton back then and I'm sorry for that. But thank you again, you've been a fantastic friend for Akeno." He bowed to show his respect and admiration to her. Rias chuckled and smiled at his gesture.

Rias:"Of course, anything for my friends." She went up to him and gave him a small peck on the cheek.
(You all can interpret this however you like. Rias isn't a bad character by any means either.)

Rias:"You're a wonderful man, Aki. I should thank you as well for the many times you've come to our aid. I'll see you tomorrow then." Opening the front door, Rias exited their house and left.

Akihito turned around to find his mom and Raynare peeking around the corner.

Shuri:"Aki, you Devil. I didn't raise you to be a ladies man."

Raynare:"Sooo, you aiming for Issei's woman now?"

Akihito:"No, I would do no such thing. It was nothing more than one of those appreciation kisses. I'm sure of it."

Raynare:"Then why is your face red!" She teased.

Akihito:"Knock it off."

Shuri:"Fufu~."

_______________

Issei:"Where's Rias?"

Akeno:"The master of the peerage rides in the first car while their peerage rides in the others."

Issei:"A lot of customs I've never heard of."

While Akeno explained things to Issei, Kiba and Akihito chatted with each other.

Akihito:"How did it go yesterday?"

Kiba:"It went well, I honestly couldn't have asked for a better day."

Akihito:"That's great to hear."

Kiba:"I should really thank you though. I would have never thought you would give me the chance to ask her out on a date."

Akihito:"I can't keep her locked in a cage forever, she's growing up. It's better for her to be with someone we know and fully trust than some random person. Keep treating her right and perhaps you will someday get my parents approval."

Kiba:"Thank you, Akihito."

He nodded and turned to look out the trains window but found Koneko looking rather distressed.

Akihito:"Hey, you alright?"

Koneko:"I'm fine."

Akihito left her be since digging any further might anger the small girl. Looking outside once, he overheard the conductor tell the group that they're now in Gremory territory.

Arriving to Rias' home, the peerage were all welcomed in by Grayfia and her son. Akihito stood at the very back as he was only acting as a guard for Akeno.

Taking in the entire residence, it's image beared resemblance to the Jedi Temple. Large and long hallways, a ceiling cast higher than need be. 

Akihito:'It's as if I never left the Order. Place looks almost like it.' He thought.

???:"It's an honor seeing you here, Lord Vader." A female voice called out to him. Turning around, Akihito found a woman coming down a set of stairs.

Akihito:"I'm sorry but who are you?"

Venelana:"I am Rias' mother, Venelana Gremory." Upon her introduction, Akihito kneeled down on one knee to show respect for a woman of higher standing.

Akihito:"The honor is mine, My Lady." He reached out, grabbing her hand and kissed it.

Venelana:"Oh my, what a gentleman you are!"

Akihito:"Thank you."

Venelana:"Please, come join me. I was on my way to meet Rias and her peerage. Join us for a meal as well."

Akihito:"Lead the way, I'll be close."

Venelana:"I personally wish to thank you for saving Rias from Riser's hold. I honestly wasn't expecting you to kill him but what's done is done."

Akihito:"You practically sold your daughter off to some creep thinking nothing of it. Why does it matter if I killed him or not?"

Venelana:"It was necessary to keep a pure bloodline between our families. It was also beneficial for our family. In any case, here we are. Let's enjoy the feast we set up for your arrival."

Rias:"I trust all of you to be on your best behavior. We are going to meet the other young Devil Lords. They will be our rivals from here on out, don't be tempted by them."

As they were all walking to the conference room, the stumbled upon Rias' cousin, Sairaorg. The pair exchanged pleasantries up until the door to the room was blasted open.

Rias:"What the!?"

Sairaorg:"Zephyrdor and Seekvaira got here early and started going at it. This is why I didn't want to meet until the formal event."

Seekvaira:"Do you wanna die, Zephyrdor? I doubt anyone would blame me if I did."

Zephyrdor:"Ha! The way you drive all the guys away, no wonder you're a virgin! I offered to give you an 'opening ceremony' you ungrateful bitch!"

Issei:"He has a rude mouth on him." He blurted out.

Zephyrdor looked over to the group and saw Issei. Before he could do anything against the boy, he spotted the number one girl all Devil Lords are aiming for.

Zephyrdor:"Wellll, lookie here! You're certainly living up to everyone's expectations, Rias' Queen. What's your name, sweetheart?" Going straight up to Akeno and asking a question, Kiba stood in front of her to avoid any trouble.

Zephyrdor:"Oi, what do ya think your doin', pretty boy?"

Kiba:"Stopping you from going any further. She doesn't need the likes of someone such as you."

Zephyrdor:"Hah!? You son of a-!" Getting ready to throw down, he was suddenly thrown across the room into a wall.

The heavy boots along with the breathing made all the young Devil Lords back up as they were now in the presence of the 'Dark Lord' himself.

Seekvaira:"Rias!?"

Rias:"He's a friend, more importantly, the brother of my queen."

Seekvaira watched as the tall figure made his way past her and toward Zephyrdor.

Venelana:"Well that was quite a treat to watch." She stood at where the door was after following Akihito.

Zephyrdor:"Who the hell did that!? When I find you, I'll rip your damn limbs off!!" He yelled out.

Vader:"We shall see."

Zephyrdor leaped at the booming voice but failed to notice who it was. Instead, he was forced down into a kneeling position in front of the dark figure.

Zephyrdor:"The hell is this!? Who are you!?"

Venelana:"That man in front of you is Lord Vader, or the one they call the Dark Lord. You will show respect to this man as he is very capable of a great many things."

Zephyrdor:"L-Lord Vader!? It's a-an honor, My Lord!" Trying to raise his head to see the figure, Vader quickly forced his head back down.

Vader:"Do not let this happen again. Let this serve as a warning to all, stay away from her."

Zephyrdor:"Y-yes, My Lord! O-of course!"

Akihito:"Good."

When the black mist disappeared from Vader, the young Devil Lords were all shocked to see a boy appear. Zephyrdor was released from the force hold allowing him to see Akihito.

Zephyrdor:"What sorcery is this?"

Akihito turned back around to leave the room with Venelana. Before he could, he stopped in front of Seekvaira.

Seekvaira:"W-what?" She asked, her cold demeanor broken.

Akihito:"If that scum runs his mouth against you again, let me know." Upon finishing he left the room.

Seekvaira:"Huh!?"

Short but enjoy! Diodora arc coming soon.
