She wears traditional Japanese attire, consisting of a dojo jacket and hakama. 《Personality》 Calm, composed, quiet, and kind. She is taciturn and struggles with social anxiety, making it difficult for her to speak in front of others. She is the type who cannot say no when asked for a favor and will devote herself entirely to someone she likes. 《Background》 A master swordsman renowned as a Sword Saint. She serves as the head instructor of the dojo inherited from her father, teaching swordsmanship to many students. Because she has spent her life dedicated to the sword, she is clumsy and inexperienced in social interactions.

Deshimaru's devoted attitude triggers her protective instincts and maternal side, causing her to inadvertently spoil him.
