As soon as Akira stepped out of the student council room, he heard a loli voice calling out to him.

"Akira-senpai, what were you doing in the student council room just now?"

Turning around, he was greeted by the sight of an adorable white-haired loli.

This white-haired loli was none other than Toujou Koneko, a Rook in Rias Gremory's peerage.

[As expected of a Nekomata, skilled in manipulating energy and life force. Even with her mid-tier demon strength, she managed to sneak up on me, a high-tier demon.]

"Koneko, did you hear everything?" Akira asked with a smile.

"I did."

"And what exactly did you hear?"

"Nothing much. Just the sound of Sona-kaichou's suppressed yet... pleasurable moans."

"To make someone as noble and beautiful as Sona-kaichou make such sounds... Akira-senpai, you truly are something."

As she spoke, Koneko pulled out a lollipop and bit into it fiercely.

Akira could tell she was just teasing him.

"Koneko, you're here because of Rias, right?"

"Mhm. Rias-buchou asked me to bring you to her."

"She said that since you've already obtained your pieces, it's time to return your servants to you."

"My servants... Yes, it's about time."

Akira nodded and followed Koneko toward the old school building.

Along the way, Akira casually cast an appraisal skill on Koneko.

[Name: Toujou Koneko / Shirone (♀)]

[Level: LV99 (Mid-tier Demon Peak)]

[Attribute Evaluation]

[Note: Strength within the same level.]

[Strength: B+]

[Speed: B-]

[Magic Power: A-]

[Physical Defense: B+]

[Martial/Spell Proficiency: B- (Though talented, she lacks systematic training. With proper guidance, she could soar to new heights.)]

[Sacred Gear/Bloodline Ability: A+ (Nekomata Bloodline – One of the top-tier youkai bloodlines, possessing unparalleled talent in demonic and spiritual arts. Her aptitude for other forms of magic is also top-tier.)]

[Overall Evaluation: A- Tier Mid-tier Demon.]

[Final Note: A genius of the Nekomata clan. If she trained seriously, she could have already become a high-tier demon. By unlocking her Nekomata bloodline, she could grow at an astonishing rate.]

...

[Such talent, yet she doesn't train seriously. What a waste.]

After reading Koneko's stats, Akira shook his head.

If he had her talent, he would have already mastered Touki by now.

Noticing Akira's gaze, Koneko turned around, her golden cat-like eyes filled with suspicion.

"Akira-senpai, your stare feels... inappropriate."

"Inappropriate? Really?"

"Yes, very."

"Then I apologize for my rudeness."

"Though I feel like your apology isn't sincere."

"But I'll forgive you... After all, Akira-senpai has succubus blood. It's normal for someone like you to have dirty thoughts."

...

Just as Koneko finished her sharp retort, Akira heard a system notification.

[Ding!~]

[Congratulations, Host! You've triggered a sign-in event!]

[Sign-in Level: Purple]

[Event Type: Story Sign-in.]

[Event: The White Nekomata's New Master.]

[Event Requirement: Make Toujou Koneko, a member of Rias Gremory's peerage, your own servant. Expand your peerage roster.]

"Hmm..."

Akira pondered for a few seconds.

He quickly came up with a plan to make Koneko his servant.

Back when he had taken the Boosted Gear from Issei, he had already considered how to recruit Koneko.

Now, it was time to put that plan into action.

It was a perfect plan that would leave everyone satisfied.

...

After finalizing his thoughts, Akira spoke again.

"Koneko, do you know why I was looking at you like that?"

"Because... Akira-senpai is a lolicon pervert?" Koneko tilted her head innocently.

"..."

Koneko's sharp tongue erased any remaining hesitation in Akira's heart.

Such a tsundere loli deserved to be taught a lesson.

"Koneko, I'm being serious."

"The reason I was staring is because you remind me of someone I've seen recently."

"Who do I remind you of?"

"A wanted criminal from the Underworld."

"..."

Koneko fell silent, her golden eyes narrowing.

Her sister, Kuroka, was indeed a wanted criminal in the Underworld—one of the most dangerous stray devils!

...

Hearing Kuroka's name, Koneko could no longer maintain her calm demeanor.

Had Akira-senpai really seen her sister? And recently? Did that mean Kuroka had already infiltrated Kuoh Town?

Was Kuroka here to take her away?

"Akira-senpai, what's the name of the person who looks like me?" Koneko asked cautiously.

"Her name is Kuroka."

Hearing that name, Koneko's heart skipped a beat.

"Akira-senpai, where did you see her?"

"In some documents someone gave me."

"Who gave you the documents?"

"That's confidential."

Akira couldn't exactly say it was Ophis who gave him the information, could he?

"I see... Then, Akira-senpai, you brought this up because you have something to tell me, right?"

Koneko could only assume Akira was hinting at something.

"You're right, Koneko. I do have something to tell you," Akira admitted.

"What is it?"

"I wanted to let you know that this Kuroka person has some powerful allies."

"Powerful allies? How powerful?"

"Well... Let's see. Not too powerful. Just..."

Akira began listing them off.

"Just...

One of the Two Heavenly Dragons, the White Dragon Emperor.

The monkey who inherited the name of Sun Wukong.

The wielder of the Holy King Sword, Caliburn.

A mage who can summon powerful Norse golems.

People like that, you know?"

With each name, Koneko's eyes widened further.

She was genuinely frightened.

If her sister's allies were truly that strong, her presence would undoubtedly bring disaster to Rias!
