Skill translation:
Each Character have 5 skill, normal attack -> Hvy attack -> Super (Requires Anger or 15 atk energy/AEN) -> Character special 1 -> Character special 2
Also training can increase skill lvl of normal and hvy attack, giving better effect.
You can find items that perma decrease cost of moves, ex. the shop sells a tome that decrease cost of 1 move of a certain character from 5 ninjutsu to 2 ninjutsu (massive upgrade)
Note some skills I've never used and wrote them down here based on what I can read, I may very well be off on some of these.
