This is my method: https://www.youtube.com/watch?v=jEwJSX9PMc0 (Skip to 0:50 cause I jabber a lot :P) Dunno if this method is practical enough for new people who wanna pick him up though.
Hayate doesn't even need 3H+K. That move is really really over abused online. He's got plenty of other tools to win the match. Most Hayate players tend to neglect his other great tools like 4P, 214P, etc. and just 3H+K all over the place lol. There's a reason why he is considered the best...
Lisa's looks so distracting in gameplay lol. Still looks good though. I'm glad Rachel's doesn't seem to clip or its hardly noticeable. Overall, I'd say Helena got the worst one in this pack. That one just straight up looks bad.
