I will add the cannon events if I can't think of anything, although I will try to give it an original twist if I add something.

Yes, Tatsumi died. I don't plan to follow the cannon for now, but I might change my mind in the future. Yes, the MC will meet Esdeath and I hadn't thought of the Yandere thing, though I wouldn't make it that extreme. Maybe just a little possessive. I was planning on doing Haren when I came up with the story since my other novel didn't have one and I wanted to try doing it. It's quite possible if there is harem, but he wouldn't get together with all the girls while he's in a world. For example, some might just be friends with the MC and still accompany him to another world and at that point maybe a relationship is generated or not. Still, I think I'll put the Harem tag so as not to confuse future readers.
