High school girl Hibiki. Thanks to her serious personality, she grew up into a girl of high standard in both physical and academic activities. Her only flaw would be her ineptitude in showing emotion, which makes many think of her as unsociable. Actually she's the most passionate among her sisters. She doesn't know that Akatsuki is jealous of her skillfulness.

It's always Hibiki! So unfair!

Popular among both boys and girls. But for now she's busy with taking care of Akatsuki and has no time for romance.

Mine is delicious.
