World Hopping System: My harem is too big!

What would you do if you randomly fell into a new world that defies common sense? The kind where people are born with strange hair colours, eye colours and body proportions unbefitting of their age? Well, Akio just so happened to be in such a world. Yep, you guessed right. He's in a world of fiction — a world where various characters from all the animes he's seen are in, and very much real. But, Akio was also given a system to traverse worlds... ——— A/N: Current World: Demon Slayer MC is a degenerate and does whatever he wants, but he has some morals. Some... If you couldn't already tell from the title; theres gonna be world hopping and lots of women. This fic will probably make you lose braincells. The original world is gonna be a mix of slice of life animes, H-anime/manga and other works without fantasy elements(somewhat realistic) Other worlds that MC can hop to can be other animes, novels, manwha, manhua and manga. MC only has knowledge on anime, H-anime and some mangas, thats about it. Reasons why this fic might not be for you: netori, harem, wincest, cliche, overpowered MC, maybe slow pace, little to no character development, personalities may be inaccurate, some harem members may be forgotten(due to world hopping). Oh, there will also be a messed up release schedule: It could range from a day or two to a week or even a month, I just write whenever I want or feel bored, so, don't expect a daily release of chapters. But... I might feel a little motivated if I see those power stones up ;) I'm also not a good writer, please give me constructive criticism! Here's a list of all the fictional works in the original world(will add more): -A silent voice -Classroom of the elite -Kuroko no basket -My dress up darling -Food wars -Various h-anime
