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.
