LOL I was thinking the same thing xD

I mean, it's Jump. What female characters do you want? Probably getting Robin and Nami from One Piece, Kagura from Gintama, Sakura and maybe Hinata from Naruto. Going back to their most popular stuff in the past, maybe Saori/Athena from Saint Seiya? Biscuit from Hunter X Hunter? Eve from Black Cat? Rukia from Bleach? Anna from Shaman King? If they're really stretching they could get the girls from Cats' Eye. There ain't exactly a bevy of popular female Jump characters from fighters to choose from.

Note that i'm not familiar with newer series like Black Clover/HeroAca so I can't speak for them.

I'm endlessly amused by the fact that Light is there especially since I'm currently reading Light and Dark: The Adventures of Dark Yagami.

Gameplay looks kinda stale, is that normal for J stars games?

Just took a look at it, it looks remarkably similar, like you said, same developer. And this was 4 years ago

Think I'll pass on this one, seems like the only draw to it is the fan service. I'd rather a 2D Fighter Z like game but with Jump characters in it. And jeez did they go overboard with particle effects. We know you know how to use them Spike Chunsoft, so can everyone else, lol
