Name’s Inori Takafuji. I’m not really much of a “go-getter,” if you catch my drift — sleep’s more my style — but getting summoned to another world kinda messed things up. Bit hard to chill when you’ve got a king in your face telling you there’s a bad guy you’ve gotta go slay or whatever, you know? Plot twist, though — it’s actually not so bad. Getting the hero treatment sounds pretty nice, right? But then it happens again! Some other clown summons me, I get my obligatory superpower, and off I go. And sure, that’s fine. It happens, sometimes you get isekai’d to the wrong place. But then it happens AGAIN! Someone ELSE summons me, I get ANOTHER superpower, and then I’m somewhere totally new. Repeat ad nauseam. No idea what’s going on, but all I want is one thing: stop !@#$ing summoning me!
