Daidoji: Now this, THIS is the absolute god-tier character of this game. Huge health, nigh unbreakable armor and hits like a 400 ton truck. Charge triangle is so strong that it basically one-shots any frail character. IF - just if - by some miracle they survive, it still launches them so you can mow them down in seconds with her Aerial Rave. As if it was not enough, it still gives her a ton of meter.
Aerial square (hold) also launches and deal unholy damage, though not as much as triangle (hold). The range of her common square attacks is deceptively huge, and you won't get beaten on 1 on 1 like ever due to Daidoji's insane endurance. N1 has a bit of a messy hitbox and isn't that good IMO. Now N2, this is the thing you want to use. Starts up immediately after inputting the move and deals massive damage, plus has a pretty decent hitbox in the vacuum effect before the punch. It can easily mow down whole groups of players, and you feel like you kick ass when you do it. I think she's the only character who can reliably kill Miyabi.
I'd argue her slightly below average speed is her one flaw, but when you pack such ridiculous damage output, this is not really an issue. I managed to win every match I played Daidoji effortlessly (even against a player that had like 200k BP) and got kicked out of rooms a lot - can't really blame the players though. The only hope one can have against this character is to ignore her and go beat the other players, while hoping the Daidoji doesn't catch up and rip you apart.
