It's not very good. the main point is that it gets too ridiculous. it starts off in a very dismally run school, where the strongest rule and the weak try to survive. a young man, who has white hair and good looks. which isn't terrible, but it's wandering into that Chuunbiyo area. he's actually good friends with Gwen Stacey, but with the possibility of something more. fine. He gets a system that allows him to stream whenever he likes, basically like alien tech. And he gets sent to alternate universes, DC, to stream from there. OK, interesting. I suppose the author wanted to give the character a reason, and so he was tricked during a multi day long streaming into buying one hundred very expensive dolls.
Rozen Maiden Dolls. so, he's not only mixing comic book worlds with anime worlds, but he's making the MC look stupid. usually the MC seems fine. he's not self-sacrificing. and he can take care of himself, he cooks and cleans just fine. but for some reason he was on a stream where he wouldn't stop until his fans stopped paying him? this is dumb. and then he gets tricked into buying something. dumb. and then apparently the dolls come to life. but only one has appeared so far. it's ridiculous.
then when he gets in, he starts to get anime powers from different universes. and we find out he can essentially time travel in different worlds.
So not only is he developing relationships with three lovely girls at his high school, also with women outside of his universe. also, the hundred dolls seem like some of them are going to be part of his harem.
DC, Marvel, Jujutsu Kaisen, Rozen Maiden, Addams Family, that's the IPs we've got so far. this is turning into another throw everything into the pot, story. where the author is trying to impress people with how many different IPs he knows.
and then there are the errors, in spelling, in grammar, etc. If you are a person who has essentially watched or read everything, and don't care about how ridiculous or over the top things get, then go ahead and read this story. otherwise, don't bother.
