真奈瀬 晶

She is one of a group of eight childhood friends centering on Yoshiya.
Although her bravado and appearance tend to make her seem like a delinquent, she is a sensible person and a maiden who has been unanimously praised as "the most decent woman" by the men.
She is a stopper and a quieter of the girls who tend to run amok in all sorts of wrong directions, but she is always at a disadvantage because she is outnumbered. Now that Shizuno has joined them, the girls of Senshinkan are no longer in anyone's control.
