Anime Gate: Devil Familia in a DxD Mashup World

(300 ps bonus)

Thanks a lot for your support! I hope you enjoy the story.

— — — — — — — 

That day.

The midday sun was blindingly bright.

Lynn walked downstairs feeling completely refreshed. Shizuka's Devil transformation was strong, but he still had the upper hand. And he even used her own ability "Milk Mode" against her.

Even though it was 2 vs. 1, he showed them why he was their master. Of course, today's focus was Shizuka.

"Having a harem is absolutely amazing," Lynn thought, enjoying the best time of his life since transmigrating.

In the Living Room

Miyamoto Rei and Takagi Saya exchanged odd glances when they saw Lynn. Their cheeks were flushed, and they avoided making eye contact.

Shizuka left the door open, so the sounds were too loud to ignore.

As the afternoon approached, around 3 PM, Lynn returned to the main world and used the world anchor from his Devil's Contract to establish a passageway to the Apocalypse World inside the Supernatural Research Club's room.

Of course, this passage could only be activated with Lynn's permission. Under normal circumstances, it just looked like a decorative door.

Even if someone outside his peerage (familia) saw it, they wouldn't think anything was strange.

Even if they tried walking through, they'd just appear on the other side of the room instead of actually traveling between worlds.

Once the setup was complete, Lynn @-tagged all the club members in their group chat, telling them to meet at the Supernatural Research Club room after class.

After that, he teleported to the shopping district, bought two smartphones, and registered two new numbers.

These were for Saeko and Shizuka so they could join the familia chat group and stay in touch more easily.

By the time he returned to the clubroom, Kasumigaoka Utaha and Yotsuya Miko were already there.

Utaha looked at him with a wounded expression. "Oh? You actually decided to come back?"

Lynn scratched his chin and replied, "Actually, I'm staying in that new world again tonight."

Utaha's face stiffened. She opened her mouth to say something, but then, like a deflated balloon, she lost all color.

"Utaha-senpai, get a hold of yourself!!" Miko shook her in a panic, afraid something was seriously wrong.

"By the way, Miko, you should let your family know that you'll be staying over there for a while too." Lynn said while looking at Utaha.

"Huh?" Miko froze.

Meanwhile, Utaha, who had just been depressed, instantly lit up again, fully revived.

So they were all going to be staying in that world together?

As long as she wasn't too far away from Lynn, that was fine!

Utaha clenched her fist, her eyes burning with determination.

She absolutely wouldn't let that sneaky cat get too far ahead!!

Lynn had arranged a training plan for them.

At 3 PM, they'd head to the Apocalypse World, then spend the entire night fighting zombies.

Once they got tired, they'd rest there and return to the main world in the morning, arriving directly at school in time for class.

Lynn mainly wanted to prevent them from falling too far behind Saeko. Miko was fine, but Utaha's personality was more competitive.

That said, some differences couldn't be overcome by sheer effort alone.

At the very least, he wanted to make sure Utaha didn't fall too far behind before she came to terms with it.

Besides, with Shizuka the Ultimate Support around, leveling up his familia was going to be easy.

During his incredible experience with her yesterday—after hours of trying things for the first time—Lynn had, by chance, already figured out how to make use of Shizuka's abilities.

Mainly her incredible milk output.

After tasting half of it himself, he confirmed its miraculous effects. 

Not only was it deliciously sweet, but its recovery boost was insane. Because of it, he could go all day without sleeping.

The remaining half? He planned to save it for when Utaha and Miko ran out of stamina while fighting monsters.

Just one sip and they'd be back to full power!

Of course, this couldn't be overused.

Their bodies wouldn't get tired, but their minds still would.

Once per day should be enough.

After Miko explained things to her mother and got permission to stay over at a friend's house for a few days, Lynn led them to the dimensional Gate marked as Apocalypse World.

Utaha and Miko curiously examined the portal.

Hearing Lynn talk about another world in their group chat hadn't really felt real before.

Especially for Utaha—she had been too focused on competing with other girls and hadn't paid much attention.

But now?

The realization that they were about to cross into another world made her nervous and excited.

An isekai, huh?

From the photos Lynn had shared, it didn't seem like a pleasant world.

But still—

Their first-ever interdimensional trip was about to begin!

"You two ready?"

Utaha and Miko took a deep breath, their expressions turning serious.

"Ready!" x2

A flash of white light filled the Supernatural Research Club room.

Apocalypse World

White light flickered in the living room.

Miyamoto Rei and Takagi Saya exchanged a glance, still unable to process what they were witnessing.

Earlier, when Lynn left, his sudden disappearance had already stunned them.

And now?

Seeing him return in the same way, but with two new girls, was even more shocking.

They were told that Lynn could travel between worlds?!

Their minds raced.

If he could move between worlds, did that mean he wasn't originally from theirs?

Could it be…That all the supernatural powers they'd seen so far came from Lynn?

After all, aside from him, Saeko, and Shizuka, there was no trace of supernatural abilities in this world.

At that moment, they felt as if they had discovered the truth!

No wonder Saeko and Shizuka treated Lynn with such respect.

And even called him Master…It all made sense now!

This realization led them to another thought—Back at their Academy, Lynn wasn't wearing their school uniform.

That only added to the credibility of their theory.

If Lynn really was the source of their powers…Did that mean they could obtain power too?

The more they thought about it, the more their gazes toward Lynn burned with intensity.

They wanted that power.

Even if it meant calling him Master as well.

As the white light faded, Utaha and Miko curiously looked around.

"Huh… Doesn't seem all that special?"

"Welcome to the Apocalypse World familia Base!" Saeko greeted them warmly.

Apocalypse World—a name Lynn had coined to represent this world.

Saeko found it quite fitting.

Hearing the voice, Utaha's eyes naturally fell on Saeko.

The sneaky cat's scent…

She scanned the four girls in the room, her eye twitching.

'Did everyone in this world have insane harmonies?!'

'They even rivaled Rias and Akeno!'

'Damn it'

Utaha, once again, lost to reality.

'Hah… The world is truly unfair.'

She spiraled into self-doubt.

Miko quickly introduced herself: "Yotsuya Miko. Just call me Miko. I only joined recently, so I'm not really a senpai."

Utaha collected herself and added, "Kasumigaoka Utaha. You can call me Utaha."

"Busujima Saeko. Just Saeko is fine."

"Uh! Shizuka is my name…"

Introductions finished, they were all somewhat acquainted now.

Utaha and Miko quickly realized only Saeko and Shizuka were official familia (peerage) members.

The other two?

Temporary extras?

But probably not for long.

The way they looked at Lynn practically screamed, Please make us yours!

Utaha smirked. 'Tch, typical.'

Lynn clapped his hands to get everyone's attention.

"Alright, let's get started."

The best way to bond?

Fight together.

"Time to grind some EXP!"
