Inu to Hasami wa Tsukaiyou

Is not running out of reincarnation ideas a bad thing or a good thing?

Reincarnation is an interesting trope, but many tensei anime involve an "Isekai" instead of simply being reborn in the same world. Specifically, I've only included shows in which the story takes place in "our" world, so the list excludes all of the fantasy slop indistinguishable from an Isekai trope.

I'm also including instances of the MC "waking up" in the distant future where the character may not have explicitly died.
