Although Kako presents herself as a calm, composed, and mature woman, this facade hides a very different personality beneath. In reality, she is promiscuous and often acts selfishly, prioritizing her own desires over the needs of others.

Additionally, Kako can be irascible and quick to anger, showing a surprisingly immature side that contrasts sharply with her professional and sophisticated appearance. Her behavior often catches those around her off guard, revealing the complexity of her character.

Kako Tengan is introduced as a highly successful and renowned lawyer, admired by Youta Narukami for her skills and reputation. Despite her professional accomplishments, her personal life is less exemplary, as she frequently indulges in her own selfish desires and acts impulsively.

Throughout the series, Kako plays a supporting role, occasionally assisting Youta and the others with legal matters or advice, though her actions are often colored by her own whims and self-interest. Her presence highlights the contrast between outward appearances of competence and the flawed, more human side beneath.

While not central to the main plot, Kako’s interactions provide comic relief and tension, as her unpredictable behavior and immature tendencies create situations that challenge or complicate the lives of those around her.
