Pick a top tier? Come on, fighting game should be about fun, Kouhei! Let your wife have fun with her character.
Kinda weird you'd do a jumping heavy kick into a Hoyokusen though. Hope this alternate Street Fighter IV lets you parry!
Chizuru-senpai's right, Kouhei and Yuzuka should learn to get along with each other. They have too many shared experiences and emotions for them to just ignore each other. Getting along as friends will make your lives much better! It doesn't have to be right away.
It is weird to have her as a senpai when she's actually younger. I wonder if she'll figure something out? She's already heard too many suspicious things.
