Yooooo my man sawatari really feels like he’s vibin hard!!!
If you decide to make the third stage there are a lot of creative ways you could do about it, you could make the japanese shrine yuya fights sawatari and sawatary dress like a abyss actor or yosenju.
Or to spice things up you could make the evil character on the third stage being you, like you could make zarc yuya fighting a scared sawatari at his lonesome.
