Someone gets hit by a bus, and after dying he ends up in a fantasy with a harem and elves. The goddess calls someone to save everyone from the Dark Lord. And my ancient heritage “simply” awakened and I learned to open portals. Yes, to another world. It seems that this is enough to drive you crazy, there’s also a planet after some kind of Armageddon, mutants on all sides, and on top of that there’s a system in your head, like in an online game. Only this is never a game. And here, it seems, after death there is no way to be reborn.
