So I just downloaded this game

I have to say, Yuki is really freaking overpowered. Her 5b (6b) 5cdc 214a dash 2b 5b (spears hit) sj 8d j.2dc 214a {3c (1 hit) 236a (spears hit) 214b 3c (3 hits) 3c (1 hit) 236a (spears hit) 3c (1/3 hit(s)) 22a 3c (3 hits) [214a datalink oki]}OR {3c (3 hits) (spears hit) 236a dash forward 6c j.c dj j.c} special is ridiculous. It takes like 90% of most character's health bars out at once, seriously. I mean, I haven't found any other combos that are as damaging as this in the game, anyone know any?
