Inside the Apartment.

Lynn looked at the blessing screen on Saeko's back and said, "Saeko, quite a few changes have happened since you reached Ultimate-Class."

"Well, aside from the power boost, I do feel something's different."

Saeko's eyes sparkled as she raised her hand.

Buzz—

A wave rippled through the space, sweeping through Lynn's apartment.

Suddenly, it was replaced by a purgatory of blades.

Inukimi, who had just returned from the Warring States Period with Saeko, was weakened from overusing her false god powers. Lying in Lynn's arms, she opened her eyes wide. "What just happened?"

Saeko didn't answer. Instead, she had a thought.

Chi Chi Chi—

Invisible slashes suddenly surged in a single direction.

Saeko was momentarily stunned.

"This is…"

"The Unlimited Blade Prison Domain," Lynn answered, handing her a copy of the blessing message.

Saeko read it carefully.

Upon seeing the description of the Domain, a glint of understanding appeared in her eyes.

She looked at one of her newly acquired development abilities.

"Killing Intent Sublimation?"

Her eyes lit up. She instinctively licked the corner of her lips. "Feels like this one's made just for me."

"It really does suit you."

Lynn glanced over the description.

The first effect was somewhat like Conqueror's Haki, used to clear weaker enemies.

The second effect was a temporary status boost.

It was a perfect fit for Saeko, who thrived in the thrill of combat.

And it wasn't just Saeko.

Lynn also gained some feedback.

He closed his eyes.

In the Zodiac Pilgrimage, the Summer Pilgrimage had now been lit up alongside the Spring one.

Summer Pilgrimage:

• Cancer Coffin – Summons star sand to form a cocoon barrier that heals internal injuries.

• Lion King Spear – Hurls a spear of condensed stellar energy. Its power scales with the user's fighting spirit.

• Virgo Libra – Expands a field that analyzes enemy weaknesses and balances certain attributes between both sides (e.g., speed, strength).

"The Summer Pilgrimage is finally unlocked."

Lynn's eyes gleamed.

Suddenly, a sweet voice echoed in his mind.

"Master, Master!"

"Stella?"

His consciousness moved to the inner space of the [Evil Piece] system.

Above the dome, constellations glimmered. From them, starry torrents cascaded down.

Ten girls surrounded Lynn, clinging to him.

"Master, Master!"

Stella looked excited. "Taurus and Virgo have awakened!"

Lynn's eyes narrowed. He entered the star palaces of Taurus and Virgo.

There, they were fast asleep in their respective palaces.

"What's going on with them?"

"Um…"

Stella thought hard, then answered in distress, "Their bodies have reformed, but their consciousness hasn't fully awakened yet."

Lynn nodded in realization.

Still…

He tested it.

[Taurus: Giant Gate] and [Virgo: Libra] were usable.

Then, he looked around at the [Evil Piece] star system.

The positions of the pieces had shifted again.

Inukimi, Kikyo, Utaha, and others occupied one sector.

Saeko, Shizuka, and others were grouped in another.

Kisara and the Cursed Children pieces had their own area.

Everything was clearly sorted.

"Reorganized by world of origin?"

He wasn't sure what kind of change this implied.

After a bit of observation, Lynn spent some time chatting with the little girls in the constellation sky, then exited the [Evil Piece] system.

"Wonder if I can let them come out and play sometime?"

Lynn rubbed his chin. He was about to close his personal panel when his gaze suddenly froze.

[Devil's Summoning Contract]

Invaded Worlds:

• High School of The Dead (Completed)

• Black Bullet (Invasion Progress: 94.78%)

• Demon Slayer (69.34%)

• Main World (5.01%)

Worlds to Be Invaded:

• Bleach, Date A Live

"Main world?"

Lynn frowned slightly.

"I'm invading… this world?"

Then a thought hit him.

He might be an outsider here?

Suddenly, his heart thumped violently.

Lynn clutched his chest.

Something felt... off.

He took a few deep breaths to calm down, then entered the strange soul state of [Four Soul Devil].

Indeed, this was a mixed world — one with High School DxD, Strike the Blood, and others — and he was a foreign entity in it.

So…

Why wasn't it counted as an invasion?

He opened his eyes, a cold glint flashing within.

"Enter. Go deeper."

Then, he looked at the invasion progress again.

"5.01%."

Lynn muttered to himself.

He really didn't hold much influence in this world yet.

That number probably only came from recruiting Peerage members here, strengthening them to Maou level, and slightly affecting the Warring States Period.

So...

What else was needed to push forward the invasion of this world?

[Devil's Summoning Contract] offered no clues.

Just like with Demon Slayer, he had to figure it out on his own.

In the strange soul state, intelligence surged into his mind.

His thoughts accelerated.

Recruiting Peerage members was one part.

The other was influence—his impact on the world itself.

After all, everything still centered around him.

Three major forces: Fallen Angels, Devils, Angels.

These were unavoidable in the world of High School DxD.

Lynn suddenly thought of the Holy Sword incident in Kuoh Town.

Maybe...

"Start with the Fallen Angels?"

He could use them as a testing ground.

He also recalled the moment he unfurled his Fallen Wings at the Supernatural Investigation Club.

Maybe he could become the new Governor of the Fallen Angels?

The idea made him laugh.

What had started as a joke now seemed more and more likely.

"Azazel, you're outdated."

"Your position should be given to the capable."

Fallen Angels, Devils, Angels.

Establish control over these three and use them to spread his influence across this world.

Because.

This world didn't just have High School DxD.

There were also monsters, vampires... even Evil Gods from other worlds.

"Tsk."

Thinking about it gave him a headache.

So much to do, just to invade one world.

"Invasion achievements... I should have some, right?"

Lynn wondered.

Aside from owning an entire Peerage, his personal feats should count for something.

He opened the [Devil's Summoning Contract] again.

Clicked into High School of The Dead.

(Merit: Saeko Busujima 32.35%, Kasumigaoka Utaha 7.8%, … 3.21%, … 1.43%)

Lynn thought for a moment.

Even combining everyone's contributions, there was still a gap of about 27%.

So...

Had the [Devil's Summoning Contract] cheated him?

[Ding! All merits related to High School of The Dead have been reserved!]

Lynn raised an eyebrow.

Okay, so it did have some conscience.

But…

What could these achievements be used for?

Lynn didn't know yet.

Still, if he kept moving forward, he'd figure it out eventually.

After finishing his observations of the [Evil Piece] system and [Devil's Summoning Contract], Saeko had also finished reviewing her Blessing and was now fully dressed.

Inukimi lay in her nest with a tired expression and sighed weakly, "I wonder when I'll be able to level up…"

Did she have to kill all the powerful monsters in this world?

She wasn't some slaughter-hungry beast.

Besides, many monsters were innocent. They couldn't just wipe them out.

Lynn patted her dog head. "It'd be nice if we could invade a few more worlds."

Inukimi's eyes lit up. "Then... is there a world for me?"

Lynn thought about it.

Demon Slayer was too low level for Inukimi. It would be better used to help others in his Peerage level up.

Even for Miko, he only asked her to go observe.

But…

If one person took all the merit... they could level up fast.

Next time a low-level world appears, he could send her there.

As for Bleach...

Inukimi alone might not be enough.

Miko's soul purification ability would be particularly effective in that world.

Hmm...

Could Yuuko sneak into Soul Society in ghost form?

Lynn was curious.

Might be worth trying.

And as for Date A Live...

He planned to take care of that personally.

Just as he was thinking.

A flash of light burst in the apartment.

A magic circle appeared.

Seeing this, Inukimi curled her lips. "Ugh, that stinky cat again."

Sure enough.

Koneko appeared in the center of the magic circle.

Lynn raised a brow. "Weren't you guys handling the Holy Sword incident?"

Koneko immediately pushed past Inukimi and curled into Lynn's arms.

Inukimi bared her teeth.

But she was in a weakened state.

A dog in distress was getting bullied by a cat.

Koneko answered calmly, "The Church said they don't trust devils. They said they don't need our help."

"I see..."

Lynn understood.

Then, he narrowed his eyes. "A guest has arrived."

Inukimi sniffed the air, then frowned in disgust. "Another stinky cat."

Buzz—

A new flash of light appeared in the apartment.

"Found you, nya~"
