Never admitting her own fault

Does not feel bad even she hurts other (or she never realized it). She always has excuses that legitimize her behavior.

"You are full of yourself." From MyGO!!!!! Episode 8, which the associated illustration is referencing.

Consolidation of power

She enjoys the satisfaction that is derived from her power as a leadership. She think she should have privilege above everyone else, and thinking she is better than everyone else.

"Give me the rest of your life" Quote she said as the formal recruitment to Ave Mujica, related to Point 1 and her fault as a serial promiser.

This b*tch drag me out to talk about this huh? In Episode 4, after Mortis claimed that she doesn't know how to play guitar, Sakiko drag her out for a talk, which fully revealed Mutsumi's DID to her.

Control freak

An almost forceful control freak. She need to control others behavior, relationship, thought, to satisfy her own ego.
