intresting ideas your sawarabi damage is quite low though xD if you have 10000 tai, you would do 1000 on direct hit and 250 when run through, also why does your jutsus have deactivation cost =/ that sounds quite annoying concept having to pay for deactivating

tsuru i think could be more intresting, i really like teshi sendan idea tho, not many jutsus ingame shoot diagonally

Deactivation cost because it wouldn't have a drain.

I don't know what else i can think of for tsuru, maybe make it a multi hit/piercing/boomerang that only goes like 4-5 tiles? user still stunned while using cause it would look weird without them stunned.
