Sakura can be a very useful dodge unit to use to tackle certain boss events, such as Behind the Ice Mask and The Mist Demon. Her dodge ninjutsu costs 4 chakra and whilst other cost 3 making them the better choice. She also has the passive heal Field Skill and also the ability to heal whilst moving on the map so could be the prefered choice. She can also be awakened to a 4* making her stats slightly better than a few of the other dodge unit choices and she can be farmed easily off of stage 4-07 so anyone can make use of her.
Ok stats for a dodge unit
Field skill gives passive healing
Healing ability makes her a better stall unit
Chakra cost for dodge is 4 whilst others can be 3
