Chizuru Houzuki

Chizuru Houzuki (崩月散鶴) is a five-year-old girl as well as a younger sister of Yuuno.

Her personality tends to be taciturn and reluctant to be in front of audience or strangers as she is likely to play alone in the kindergarten.

She yearns Shinkuro as a brother and she also have affection toward him, as Shinkuro calls her "Chi-chan".

However, Ginko suggests that "Chizuru would be likely to be stronger than Shinkuro, as she belongs in the lineage of Houzuki to deserve a powerful Senki amid her period of an apprentice."

In anime adaptation, Chizuru likes video games as she plays video game console but the device is broken by Murasaki amid vehement disposition. And later on, Shinkuro compensates the device for Chizuru.
