Sure. Actually 2 of the characters I mentioned is from anime/visual novel.
Okabe rintarou is from anime called Steins Gate. Here the ML tries hard to save his precious childhood friend and the FL.
The concept here is time machine/time leap/different world line (kinda like parallel world settings). The story starts off slow burn like your typical slice of life but when you reached ep 12, everything hits like a truck. If you are interested there's a watch order:
Steins Gate(2011)(ep 1-22)
Steins Gate 0(2018)
Steins Gate(2011)(ep 23-24)
The second one is Akemi Homura. She is from the anime called Madoka Magical. At first this anime may seems like silly Magical girl anime but when ep 3 came around, just prepare your heart because lot of angst coming. The concept here is time rewinding where she keeps on rewinding time to save her friend Madoka Kaname. It is implied that Homura had romantic feelings for Madoka basically making this story a bit of a GL(Yuri).
The continuation for this anime is Madoka Magical Rebellion.
The third one is already pretty well known, he is Kim Dokja, the MC from Mahwa Omniscience Reader Viewpoint(ORV). The manhwa is pretty good, as it is set with game-like system and post-apocalyptic settings. The manhwa cuts a lot of things, so I recommend reading the novel instead.
As for the BL manhwa category, I've read a few that I considered quite good.

This manhwa awakened the okabe rintarou, akemi homura and Kim dokja PTSD within me. I'm a sucker for regression plot but every single one of them never fails to make me crying ugly
