Litchi doesn't care about their goal though I think, she is just so hell-bent on saving Arakune it's making her kinda blind.
Above all though I'm just really worried Litchi may die at some point, especially after seeing her bad ending. Though, after playing Tager's story and seeing how much Linhua looks up to Litchi, it would be pretty epic if Linhua adopted Litchi's fighting style and replaced her, if it happened.
Not saying I want it to happen, just if Litchi has to go, that's how I would want it. Why do my favorite characters in games always die or have near-death ailments? Ever since I played Final Fantasy 7....
