After 10 failed career runs I caved and tried Bakushin, what a beast.
She just smashed through everything undefeated with max speed by the end. Almost lost to a cursed 3 man box blockade but she somehow found a way through that at the last moment as well.

I will get her racing outfit and then we'll win it again!
I will 5 star her and then we'll win it again!
I will get her Sports Festival alt in the future and then we'll win it again!
She will always be special to me.

BAKUSHIN
