Mayuzumi Yukie

Often called "Mayucchi" for short, Yukie is a first year transfer student that has tasked herself with making one hundred friends. As the first daughter of the sword master Mayuzumi Taisei, Yukie has not been exposed to many people and severely lacks social skills. This has led to her scaring people away with her extreme reactions and bashfulness. The fact that her cell phone strap (named Matsukaze) "talks" due to a skill in ventriloquism that she developed subconsciously doesn't help at all. She starts out with Matsukaze as her only friend, but Shouichi finds her interesting enough that he allows her to join the Kazama Family.

Yukie quickly proves herself to be a very capable girl, as she is a fast learner and excels at everything she puts effort into. She is also a very strong fighter, near if not on the same power level as Momoyo. Her main weakness is her bashfulness, which the members of the family try to help her overcome. In the end, Yukie becomes forced to part ways with Matsukaze in order to become a stronger person.

Aside from her skills with the sword, Yukie is designed around the yamato nadeshiko archetype, as demonstrated by her culinary and domestic skills as well as her willingness to do as Yamato says.

Yukie's virtue of Bushido is Rei (Respect, or 礼).
