Yuna Suzune

Yuna is a member of the gang, and is known for her samurai garb, large breasts and eyepatch (when she doesn't wear her eyepatch her hair covers her eye). She is often seen wielding a bokuto and very skilled with it. She is known to be the most battle-hungry of the gang. She is also the most protective of Saya, going as far as to dress up "lady-like" to fool Saya's sister, and at practically any moment will come and fight (most of the time it being Tadashi under a misunderstanding). She has a habit of grabbing Tadashi to where his head is against her breasts, though she seems to be unaware of this habit. She is displayed as a tomboy to the point some believe she is really a guy, though she has a desire to appear more girly.

However, she usually attacks anyone nearby out of embarrassment after doing something she considers girly. She has started to show feelings for the Student Council President after he told her that if anyone made fun of her for being more girly he would "purify them", but will try to beat him out of embarrassment, even if she thinks about him in another room she will run over to where he is and beat him.

She is considered dumb, as she nearly was able to figure out that Saya and Tadashi were dating, only to stop because her head started to hurt from thinking. She seems to have become addicted to mushrooms after eating them. She is later shown to have a brother, where ironically he is mistaken to be a girl, looking like a younger and more feminine version of Yuna, while wearing women's clothing. However, he is much stronger than her and inline to inherit the family Dojo, who wishes to change it to be completely girly. This also shows the reason Yuna first joined up with Saya was because her amazement of her strength and her wish for Saya to train her so she could defeat her brother.
