Interesting Isekai concept. This certainly has potential but it will probably, nonetheless, end up like most mangas where they get worse by the chapter, but it's too early to judge.
I just hope that their background story will also be explained because the is the first time I've seen an imouto...
this was a shitty ride. I thought that domestic kanojo was the only retarded dumpster fire but no..... I guess Hare-Kon is a contender for the place of shittiest wanna be sophisticated adult harem manga.
Hori is a cold blooded bitch. Trying to joke about shit like that. Who knows what the bitch might do if she's really mad. Miyamura should dump her ass.
