Kirino Chiba is a second year high school student, and the captain of the kendo club. Energetic and enthusiastic, she dreams of leading the team to the nationals. Her family owns a deli named "Chiba Deli". Kirino is very happy that Kojirō has finally begun to put more effort into training his kendo team, but she is oblivious to the real reason that her teacher has suddenly begun to train the team so enthusiastically. She is proud that she is the captain of the kendo club and is more responsible than she appears (i.e., picking up the shinai when the other members leave them lying around on the floor, chiding the other members for not picking up after themselves, etc.). Despite that, however, she has great confidence in Tamaki. She is described as being the heart of the group by Kojirō.
