Chapter 26: The Candidates for the Pet Collar

"Alright, Gasper, from now on, you are officially my vassal."

"During the time I entrusted you to Rias, did you train properly?"

Lucien gently stroked Gasper's golden hair, pinching her soft, smooth cheeks.

"Yes! Lord Lucien!"

"For Lord Lucien's dream! And to accomplish what I couldn't before, I have been diligently training!"

Gasper straightened up, standing at attention as she responded seriously.

"Is that so? That's something to look forward to."

Lucien smiled and cast an appraisal spell.

[Name: Gasper Vladi (♀)]

[Level: Lv.125 (Mid-Tier High-Class Devil)]

[Attribute Evaluation]

[Note: Strength within the same level]

Strength: D

Speed: C

Magic Power: C+

Physical Toughness: D

Martial Arts or Spellcraft Proficiency: C (No talent in martial arts, but possesses aptitude in certain vampire and dark magic techniques.)

Sacred Gear or Bloodline Abilities: SS+

(1) Vampire Bloodline: As a hybrid of human and vampire, she possesses some vampire traits and talents, including transformation into a bat and strength enhancement through blood consumption.

(2) Sacred Gear – Forbidden Balor View: A time-based Sacred Gear derived from the power of the demon god Balor, capable of freezing the time of objects or people within sight.

(3) Demon God Balor's Reincarnation: Gasper harbors the latent power of the Demon God Balor within her. The "Forbidden Balor View" is a manifestation of Balor's "Eyes of Death." Under special circumstances, Gasper can tap into Balor's power, manipulate darkness, and summon creatures of the night. The damage inflicted by these creatures ignores defenses and cannot be healed even by the Holy Grail of the Netherworld.

[Overall Evaluation: SS-Class High-Class Devil]

[Summary: A vampire with unlimited potential. If she fully develops the latent power of Balor within her, she will inevitably become a top-tier powerhouse.]

"A High-Class Devil… It seems you've truly worked hard, Gasper."

Lucien was pleased as he continued to pat Gasper's head.

Even if he lost his title as Leviathan's heir, he could still live comfortably just by relying on Gasper.

Taking out a special piece from his stash, he placed it in Gasper's palm.

A crimson glow filled the room.

Lucien officially completed the final step in reclaiming his vassal from Rias.

"This feeling…!"

Gasper's pupils dilated in shock.

After absorbing the piece, the power within her multiplied tenfold! She had directly advanced to the level of a High-Class Devil!

Whoosh!

Ten Devil wings unfolded from her back, leaving everyone in the room, except for Lucien, stunned.

"Gasper, why do you have ten wings?" Rias was shocked. Ten wings meant she was destined to at least reach the level of a Maou, possibly even surpassing that in the future!

"I… I don't know either."

"I just felt an overwhelming surge of power… and suddenly, the wings appeared."

Gasper's voice was soft as she answered timidly.

"Lucien! What is going on?!" Rias demanded, looking at him urgently.

Lucien remained composed, observing Gasper's new form with satisfaction.

"Rias, this is my newly awakened ability—Refinement and Evolution."

"My Devil Pieces have undergone an evolution. They can now fully unlock my vassals' innate potential."

Lucien openly shared his ability.

Since he had already secured cooperation with Rias and gained the unofficial status of Maou Lucifer's brother-in-law, there was no need to hide it.

The only thing he needed to keep hidden was his "High-Dimensional Leviathan Bloodline Awakening."

"Your pieces evolved…"

"That means Koneko can too!" Rias swallowed hard.

"Yes, Koneko can also unlock her abilities through my Devil Pieces."

"Koneko."

"Are you willing to embrace your potential?"

"If you still reject your Nekoshou bloodline and refuse to grow stronger, I will allow you to withdraw."

Koneko's golden pupils sharpened, and she extended her small hands toward Lucien.

"Lucien-senpai… I'm willing…"

"Since Gasper is stronger than me now, I believe that even if I lose control, Gasper can stop me."

"Besides, Lucien-senpai, I trust that since you were able to guide Agumon and Gasper, you can also guide me."

With that, Koneko took the Rook piece from Lucien's hand.

Seconds later.

Under Rias's increasingly exasperated gaze, Koneko completed the final step of the exchange process.

"Lucien-senpai, from now on, please take care of me."

"After absorbing the piece, I've reached the peak of a High-Class Devil. I believe I will soon reach the Ultimate-Class."

Just as Koneko finished speaking, Lucien heard the system notification.

[Ding!~]

[Congratulations, Host! Mission Completed!]

[Mission Rank: Purple]

[Mission Type: Event-Based Sign-In]

[Mission: The New Master of the White Cat Youkai]

[Reward: Pet Collars (x3)]

[Pet Collars: As the name suggests, these are collars for pets. However, the system's pet collars transcend mere symbolism—they defy causality.]

[Rather than a pet wearing the collar, anyone who wears this collar will become the Host's pet.]

[Aside from subjugation effects, the collars are aesthetically pleasing and can transform into various accessories—necklaces, pendants, and even become invisible.]

[Note: The target must have no resistance to the collar when applied.]

"..."

Lucien stared at the rewards in silence.

Hmm… He felt like he was walking further and further down the path of a degenerate villain.

But.

So be it.

If he wasn't at least this much of a villain, what kind of transmigrator would he be?

Before long, he started listing potential candidates for the pet collar.

[Serafall, Grayfia, Griselda, Gabriel, Roygun.]

Not everyone could be turned into a vassal.

His black and white pieces could mimic standard pieces, but they couldn't completely disappear; they would still be detectable.

Using them to control key figures carried the risk of exposure.

But with the pet collars…

That concern was completely eliminated.
