Kobeni is exceptionally cowardly with few moments of courage. Her first confrontation with the Eternity Devil leads to her being paralyzed with fright and babbling. She is shown to easily crack under pressure and breaks down in tears. However, when Kobeni gets into action she had proven to be cool-headed and efficient, ruthlessly dealing with both the Katana Man and Akane Sawatari and forcing them to retreat, only breaking down in a panic once the fighting is over. She likes Ice Cream.
