Living Life in a Multi-Crossover World

Rey Takami transmigrates into a new body, coincidentally also called Rey Takami. He thinks that his new life would just be an ordinary one, but he quickly finds out it isn't once he gets his system and sees characters from multiple fictional series.

Inspired by novels such as akikan's stories, and a few more.

WARNING/TAGS:
-Harem, if i see one comment/review about someone complaining about there being a harem even though I've made it clear by now that there will be harem, I swear to god, I will find your family and make them into my harem.
-System, if you don't like systems, oh well, there's going to be a system in this one like most of my other stories
-Non-realistic relationships, this was gonna be kinda obvious since it's a harem, but it's a fanfiction so it doesn't matter
-A lot of fanfiction logic
-A lot of multiverse-crossing (Whatever the word is)
-Story will be first person, but there will be different PoV's obviously
-Alternate Universe, most of this will literally be made up practically, timelines will not be perfect, age will not match up at all, i'm purely making everyone i want the same age coz why not.
-Group Chat, while MC will be living in a world with characters from slice of life, he'll also have a group chat, which will consist of animes from shounens and animes that obviously definitely wouldn't exist in a real world, even though anime doesn't exist but yk what i mean
-Many crossovers. that's all i gotta say
