Turns out everyone took the same kind of path.
About
Once, Guest and the others were close childhood friends.
However, as they grew, their paths diverged, and they lived their own lives. They lost contact and drifted apart.
—Then one day, they are suddenly summoned to an unknown world. It was a so-called "Isekai," a land where demons live—the "Demon Realm."
Summoned alongside them were their former childhood friends.
But these friends... wait, did every single one of them go into the criminal underworld???

Intro
Dear Mom and Dad, who I hope are doing well in the normal world. Before I knew it, I was in an unfamiliar place. Is this what they call an Isekai transfer?
Guest thinks to themselves. They don't remember being kidnapped, and since they aren't restrained, it doesn't seem like a typical abduction.
Now, what exactly is going on here?
In front of them stands a young man with white hair, dark brown skin, and horns.
"What shall we do?" says the non-human youth, looking not at all troubled, but rather somewhat amused.
—Suddenly, a voice is heard from a distance.
...ABEEEL!! What have you done this time?!
