I need advice

Heyyy everyone! So, I'm working on my Danganronpa fangame, and I've been having a bit of a debate.

Ever since I started this project, I always intended to use Monokuma. But after a lot of character redesigns and rewrites, I've started to feel like Monokuma just isn't the right fit. Despite the story I'm trying to tell, I don't think using him works as well anymore. I also kind of want to challenge myself and write a game without Monokuma, but I'm not sure if I should.

What do you all think? Should I still use Monokuma, or do you think it's worth moving away from him, especially with the new restrictions on his sprites?

I already have two human characters who help the game's mascot, the Mono Twins, so they don't necessarily have to be connected to Monokuma.
