Her irritation with him came to a peak when, affected by a cold, she challenged him to a kendo duel in an attempt to get rid of him.
Due to Keitaro’s panicking and Motoko’s own illness, they were both knocked out during the match (Chapter 6).
As a result she is somewhat naive to the “ways of the world” and is sometimes confused and irritated by the mannerisms and attitudes of other girls her age.
Her appearance and clothing resembles that of traditional Japan, often only seen wearing either her school uniform, sports uniform or her training hakama.
She would, again, lose, resulting in her abiding in Keitaro’s request to act more feminine.
After many failed attempts at being “more feminine” Keitaro shows her the compassion and understanding that she had never shown him by retracting the command and saying that it was okay to act like she normaly did.
Kaolla Su immediately latched on to her as her play partner; a job Motoko stoically tolerated.
Dubbed “Kendo Girl” by others, Motoko is born into the head family of the Shinmei-ryu School of Martial Arts; a school of swordswomen who act as demon slayers and exorcists in Japan, and is next in line to inherit ownership of the school.
