Whenever she mets a villain she acts very competitive and mean, with no signs of feelings. But when she's around her friends, she deeply cares about them and protects them. Whenever she does something wrong, she's always silent and talks to herself most of the time, she'll eventually apologize for something she did wrong. While cheery and friendly towards her friends. Her attitude to her enemies, threats, villains, is completely the opposite, she'll stop at nothing to defeat them even if she's at the verge of death, she does not give mercy, unless they surrender. Rarely, if the enemies wants to join her team or sincerely apologizes, she forgives them and lets them go/or lets them in her team but If they trick her or even cause one bit of trouble she'll just lock them up in jail.
She uses the "hit and run" technique but if cornered, she uses smoke bombs to escape or slash her way out by using her dagger. She also has punching gloves, but she can only use them when she has no weapon left. She tends to have friends help her along battle. Whenever finding an enemy, she ambushes them.
