Takumi Takahashi in the Multiverse

After crossing into an anime mashup world, Takumi Takahashi barely had time to enjoy his youth before being bombarded by evil spirits, cursed entities, ghouls, and monsters. Slacking off was never an option—survival meant working for the System that brought him here.

Miko Yotsuya: "With Takahashi around, I actually feel safe for once."

Yukino Yukinoshita: "Now that I know the truth of this world, I must save more people. You'll help me, won't you?"

Kaguya Shinomiya: "Today, I’ll make Takumi Takahashi confess to me—or else…"

Utaha Kasumigaoka: "Senpai, care to help me... find inspiration?"

A harem of heroines who don’t realize they’re in a death game.

Traveling to the world of Demon High School, Vitan Asmodeus met the legendary magic book Radix Astyr.

Embarking on a journey through the dimensional world!

In the world of the mechanical girl, mastered the seventy-two pillars of the devil, understood Sloth, and became the devil body Berial.

In the dark bullet world, judged the ignorant and selfish humans, understood Pride, and became the devil Lucifer.

In the world of the date, controlled the Kabbalah Tree of Life, understood lust, and became the devil Asmodeus.

In the sword dance of the elves, swallowed the world, understood gluttony, and became the devil Beelzebub...

In

the box garden, the great devil of the final trial of mankind, Vitan Asmodeus, looked at the many beautiful women in his community and couldn't help being silent!

Why do I have so many harems!

My name is Imazumi Rinnaeus, and I'm a transmigrator.

As a transmigrator, I naturally came equipped with a golden finger system.

My system is called the Dream Performance System. As long as I complete performances according to the script, I can receive rewards in the form of "tags."

Those max-level attributes, talents, skills, and even tags for health and longevity look truly enticing.

However, this damn system took over a decade just to activate, and the first script it gave me left me speechless.

Because this script... isn’t something one person can complete alone. It requires the cooperation of several girls.

For heaven’s sake, even in open-minded Japan, what decent girl would agree to this kind of script?

...

"My name is Nakano Ichika."

"My name is Nakano Nino."

"My name is Nakano Miku."

"My name is Nakano Yotsuba."

"My name is Nakano Itsuki."

Today, they accepted an invitation from a certain "great system." In order to achieve their respective goals, they decided to seek out someone with the surname Imazumi and perform the script together.

It’s just that this script... is way too embarrassing...

"Rainy Night, Overpass, Maybach."

Crash.

...

When sitting alone, he often caught himself thinking about her—the girl who had shadowed him for years. He’d imagine her barging into the restaurant, drawing every gaze, then plopping down beside him, propping her chin on her hands as she stared into his eyes.

"Buy me a cola," she’d say.

But tonight, to his surprise, another girl actually did sit next to him.

...

Blue hair. Delicate. Radiantly sociable. A checklist of desirable traits.

Yet when it came to love, she was bafflingly cowardly.

Even his unluckiest junior never got to drink their senpai’s leftovers—but Banaumi did it without trying.

Too scared to confess. Clinging to "I’m fine" while heartbroken. Binge-eating after rejection. When urged to fight for her feelings, she’d just whisper, "I hope they’re happy."

He kept seeing that other girl in her—until he blinked, and a stranger’s face stared back.

A stranger who wasn’t even the same gender.
