Because I can. I made that Nobukatsu sprite myself. What of it?
I figured if I really are going to make that “Ninja Love Expansion: Romance goddamn Nobunaga” troll game, I need more side characters. Seriously. Going by what I drafted thus far, you’re gonna spend most of the story NOT seeing much of the ninjas (no duh), and it’s gonna be boring to be around the castle and not seeing any sprites other than Nobunaga and Akechi (and maybe Oriku). So yeah. Nobukatsu.
Just in case you’re now wondering “WTF, how old is Nobunaga, then? His son looks about Hanzo’s age!”… Well, that is sort of part of the drama, so I’m not saying anything in case I actually do get around making the fangame for real. I’ll only start rambling about it when I declare the project dead.
