Again, more of a personal thing, because I forget names easily. Also because I'm trying to see if I'm right about me having a "type" when it comes to fictional guys. Speaking of, this is just the guys. I do have favorite female characters, as well, but because of the previous point I won't be listing them here.

These are just the ones I could think of for now, I'll probably go back to this at some point. Though I'll likely just stick to the more well-known manga, since I've read a lot with like less than chapters.

italics - absolute favorite (outside of main protagonists unless stated otherwise)

If there's any manga/anime I didn't list here this time that you're interested in (as in, learning just which characters I obsess over from them) then feel free to tell me which one and I'll try to add it in!
