Momonga's POV.

At my office, I used the item, the mirror of Remote observation which is very helpful to me to secure the areas around Nazarick without even going in there personally.

I'm still starring on the mirror when I hear Eve's voice via Message skill.

[Eve: Lord Momonga, Lady Y/n escape once I arrived to the sanctuary.]

My little sister is always giving me a bunch of headaches. I ordered Eve to fetch her back to my office to discuss something, but she seems.. misunderstood it.

Momonga: Do you know where'd she go?

[Eve: Negative. I ask Aureole Omega but she didn't know either.]

Momonga: I see, come back to my office now.

[Eve: As you wish, Lord Momonga.]

As the message skill ends, I focused back to the mirror while Sebas is watching me. Now, let's search for areas that could potentially be populated. After some searching, I saw a little village and..some shadow movements? The mirror was to far from it so I can't clearly see.

Momonga: Is that a festival?

Sebas step closer and gaze to the mirror.

Sebas: It does not seem so.

We heard a knock on the door, Sebas opened it and Eve enters and bow before standing on my side. Back to my work, i zoomed the mirror's vision enough to see the movements more visibly detailed. Some shimmering thin foils riding on their horses killed the villagers mercilessly.

Momonga: They don't appear to be bandits.

I saw them killing people mercilessly and I didn't faint at all? How can I watched this scenery so calmly? Swiping the mirror to get a better angle, then the mirror hits something, my eyes lightly shocked when I saw a human-like form hiding under the tree and happily sucking blood from one of the wounded villager.

What in the hell is she doing there!

Sebas: Is that.. Lady Y/n, Lord Momonga?

Momonga: (She take this little brawl to cover her killing tracks? Very clever Y/n.) So, that's what where she went?

Eve: Lord Momonga, do you want me to take her back to Nazarick?

Momonga: ...no. Let her be. She seems hungry and that requires human blood and flesh to replenished it.

Eve: But..it is dangerous o-

Momonga: don't worry about her, she's a supreme being like me so..a simple threat can't harm her, although, I do not condemn her careless acts.

Eve: yes, Lord Momonga.

Sebas: What shall we do?

Momonga: Leave them be. We have nothing to gain by saving them. I'll let Y/n to remain there so she can have her 'meal' before I sent her back.

Sebas: Understood.

I looked at Sebas, he reminds me of Touch-me-san so much. Well, he create Sebas after all but..Sebas also inherit Touch-me-san's heroine behavior.

One funny memory plays back on my mind. Then I laughed by Touch-me-san's common sense. Well, I've eventually got to test out my strength in this world. The mirror angles to the other site again, then two young villagers hit the visions, they were running away from the knights.

Hm..I got to do something...

Momonga: Sebas, I am heading to this village, raise Nazarick's security level to maximum.

Sebas: Yes, sir.

Momonga: Tell Albedo to join me, fully armed. As well as to you Eve. After that, prepare the reserve forces. Send a few soldiers that either excel at stealth or have the invisibility skill.

Sebas: Understood.

Eve: As you wish, my lord.

It looks like the time has come to repay my debt on Touch-me-san. I summoned my staff and call a gate. Eve was fully armed behind me and we went to the two mortal villagers whom in the middle of their death sentence.

No one's POV.

The little girl starts to tremble when she see her elder sister received a hard slash that gave a long wound on her back.

???: Sis..

The Knight chuckles underneath his armour and raised his sword to give a finishing blow on the two. The other girl hugged her little sister tightly.

???: Nemu!

But the three knights stopped as they saw a big purple dimension appears out of nowhere. The elder girl frowned when she saw the knights looking at their back, shaking.

Knight 1: what the hell is that?!

The elder girl look behind and saw a weird dimension behind them and the Overlord appears with a Chevalier behind him. They quivered in fear as they saw them stands with pure pride.

Momonga: Grasp heart.

The overlord raise his hand and clutch the heart image targeting one of the knights and squish it, the Knight falls down to the ground. His hand gushes more blood as he look amazed in his favorite undead spell.

Knight 2: A mon-

The other knight didn't finish his sentence as the Winged Chevalier quickly chopped his head off with her dark glittering sword.

Eve: Silence...you have no right to say those words in front of my lord.

The last knight is now shaking in fear. As the overlord steps closer, the cowardly Knight stands on his battle form showing he's not completely afraid to the two but he's act only earned a chuckles to the overlord.

Momonga: You chase after women and children, yet are enable to face anyone different from yourselves? We bothered to come all the way here so I will have you both assist me with my testing.

Knight 3: *gulp*

Momonga: Dragon Lightning!

The knight starts to run but sadly, the lightning pursue and directly hit him. He falls to the ground smoking and toast insides.

Momonga: What a weakling. He died quickly to mere 5th tier magic. Raise Mid-tier undead. Death knight!

A blue purple aura shows through the air and takes over the knight's body and transformed into a hideous death Knight.

Momonga: Death knight, kill the knights that are attacking this village.

The death knight growls before making its way to the village. He saw the death knight running away from him. Then, the overlord hear a insanely laughter at the top of a tree, he look up and saw the arch devil in her concealing form, sitting happily on a large branch.

Y/n: Hahaha, what's the point of summoning a defensive minion leaving behind the one who he's supposed to protect?

Momonga: Y/n. Are you done having your meal?

Y/n: Hm..? Yea, I think so.

Momonga: Good. Now, don't you ever do such clumsy things like intruding a bloody annihilation without my permission. Do you understand?

Y/n: Yeah. Yeah. I got it. Change topic, why did you come here with Eve? Do you want to save their village?

Momonga: I just want to test my powers in this world Y/n. Don't think too much.

Y/n: Hm. I also want to test my strength here Aniki. Can I kill too?

Momonga: These knights are completely useless. I will find a better assistant for your own testing later.

Y/n: Aww..man!

The Arch devil levitate towards to the girls who still in shock when they were saved by these monsters to the knights.

Y/n: Her wound is truly long and deep. Poor thing, are you alright?

???: Y-yes.

Y/n's eyes turned red as she grinned at the elder girl.

Y/n: Lies.

The elder girl starts to shake in fear hugging the younger ones on her chest.

Momonga: Y/n. Stop. They have enough.

Y/n: heh, I'm just asking them but she lied on me. You know I hate liars. *pout*

Momonga: *Sigh*

Albedo starts to show up on the gate, wearing her battle armour and her axe before the gate vanish.

Albedo: Preparations took longer than expected, my apologies.

Momonga: Not at problem. You're timing is accurate and precised, Albedo.

Albedo: Thank you very much. Now, what would you like me todo with these lower life forms?

Momonga: For a moment...

Y/n: Can I suck their blood's out? *Smile*

Momonga: *Sigh* Eve.

Eve: Yes, my lord.

Eve quickly wrap her arms on Y/n's body entrapping her on a bear hug. Y/n starts squirming but she know it was futile to fight back, so only glared daggers on Momonga.

Eve: Done, my lord.

Momonga: That should do it. Now, our enemies are the ones clad in that armour Albedo.

Albedo: Understood.

Momonga scanned the elder girl's wound and summon a healing position on his bonely hand.

Momonga: Here, take this.

???: Blood?! I-i'll drink it! But my little sister..

She was going to take the potion when her little sister mingled and stop her hand from reaching it.

Nemu: Don't do it, Sis!

The sister's were having an argument and Albedo didn't like their doubtful thoughts to Momonga. She swing her axe and ready to strike them.

Albedo: You lower life forms!

Before the axe could hit them, Y/n suddenly appears in front of them and block it with her weapon. A loud clash of metal resounds through the whole area as the others leave in shock.

Albedo: L-Lady Y/n!

Y/n: Whew... That was close.

Momonga turned his gaze on Eve, she doesn't know how Y/n slip on her arms before she could noticed it. Y/n only chuckles at their bewilderment and Eve's confuse look.

Momonga: Albedo, Lower your weapon! Like I said, They are not the enemy we supposed to kill.

Albedo: Understood. I'm terribly sorry, Lord Momonga, Lady Y/n.

Y/n: Nah..its alright.

Momonga turned back on the two humans.

Momonga: This is a healing potion. Drink it quickly if you want to live for your younger sister.

The elder sister take a potion and drink it. The long wound on her back quickly heals, not leaving any scratch. She was amazed how the potion work on her flawlessly.

???: N-no way.

Momonga: I know this is kind of a sudden to ask but...Do you know what magic is?

Y/n: Ha? That's a stupid question of y-

Momonga: Eve.

Y/n: W-whoa! I'm just kidd–..GYAAAH!?

Eve tackled poor Y/n through the air and covered her mouth with her hand and the other hand wraps on her waist. Still, squirming to get free. Eve used her wings and cocooned Y/n to stop her movements temporarily, so escaping is merely impossible..for now.

Momonga: *sigh*

???: Y-yes sir. A friend of mine, a pharmacist, sometimes comes to the village and uses magic.

Momonga: I see. Explaining should be trivial, then. Me and the white haired young girl over there are also magic casters.

Momonga cast some spells to protect them.

Momonga: Anti-life cocoon, wall protection from arrows.

It creates a yellow green forcefield enveloping the two inside.

Momonga: I have cast protection magic on you. You are safe as long as you stay there. Also, these are now yours, just in case. If you blow them, an army of goblins under your command will appear before you. Use the items to protect yourselves. Albedo, Eve, Let's go.

Albedo/ Eve: Yes, Lord Momonga.

???: U-um..th-thank you very much for saving us!

Momonga: Think nothing of it.

???: M-may I ask your name?

Momonga: My name? You would do well to remember my name. I am...Ains Ooal Gown!

Y/n: Hm...sounds good brother but..you are forgetting something..

Y/n escapes again making Eve simmer in anger. Momonga knew what Y/n is trying to say and with his staff, they teleport to the village where the death knight kills the knights as Momonga ordered.

Y/n: Oh my? Are we having a bloody party here? *Shaking in excitement* I would love to join death knight's killing spree!

Momonga: Hm. Restrain yourself Y/n. We must observe for a moment so don't do anything stupid or else, I'll let Eve to drag you back to the Nazarick and punished you approximately.

Eve: *Smile*

Y/n: O-okay! No need to remind me. Geez...

The death knight snarls loudly making all the knights terrified and its still attacks to kill them one by one. When Momonga sees that half of the knights were dead, he is satisfied and call his death knight.

Momonga: Death Knight! That's enough.

The Death Knight stops from moving. The villagers saw them floating through the air, Momonga wears a mask of jealousy and metal gauntlets to conceal his skeletonial figure. They land smoothly to the ground except for Y/n that levitates on their height. She still on her human-like form.

Momonga: Nice to meet you all. My name is Ains Ooal Gown. I shall have you all return alive and let your superi- your owner know this! The next time you cause trouble in this area, I will bring death to your kingdom.

Knight 4: M-monsters!

Y/n: You'd better run now and spread my brother's name in your kingdom before I changed my mind and drag all of you to HELL!?

Y/n's black purple aura and Red eyes shows up as she grins psychopathically. All of the knight tremble and drop their weapons and run away with fear.

Y/n: Stupid mortal thin foils!

Momonga: Enough, Y/n. You are scaring the villagers too.

Y/n: Tch. Alright.

Villager: Y-you.. Who are you?

Momonga: I've noticed that this village was under attack and I came to save you.

Y/n: Nailed it. *Grin*

Momonga: Grr..

Y/n: *Chuckling nervously*

Momonga: Now, the threat has passed. I wish for you all to be at ease. However, my services come at a price. I would like a token of your gratitude.

After all the crazy happening lately, Momonga ask many things to the village chief of this village. He wants information which they didn't hesitate to share.
