ibuki hana

A sickly girl who arrives later in the manga because she has been hospitalized since before the start. She appears to be Kawai's opposite in every way as she is cheerful and popular. When she first returned to school, she noticed the necklace the teacher took from Kawai, which he then gives her (seemingly as a way to get Kawai expelled in hopes she would attack Hana to get it back). However, she instead tries to befriend Kawai, which goes well. Until she discovers that Yuusuke confessed to Kawai. As she has feelings for Yuusuke and had earlier asked if Kawai had feelings for him, which Kawai denied, she believes Kawai is lying. Because of her outbursts, Kawai believes that she is only doing this because she likes the attention. This might be true as, with anything that happens, she is prone to emotional outbursts that draw the rest of the class's attention, shown when Kawai casually pointed out that the cross was missing from the necklace, leading her to have an emotional outburst about it being missing. At the end of chapter 17, it appears that Hana is losing her sanity, smiling evilly with a blank look in her eyes. Later, she conspires with classmates against Kawai to make everyone hate her by setting her up with vicious comments about other students in her bag. However, this quickly falls apart when Shin points out that she says what she feels without hesitation and wouldn't write those things, and Kawai sees through Hana's "help". Later, she sets Kawai up to make it look like she really did write the comments and ultimately suggests splitting up the group. In the end, she is stated to be the head of the group. This causes Kawai to show aggression for the first time, as she was truly dedicated to her role as the Choir Leader. Correcting Hana when she thought that Kawai hated her, Kawai clarifies that she just didn't see her as a friend, calling her a Bad Friend. However, Hana finally shows her true colors and confirms that the teachers only set up Kawai as the Leader to promote the school. Hana makes a conspiracy against Kawai to make herself look good at the choir competition. Hana finds out that reporters are going to be there. She gets even madder when Kawai ruins her plan 'accidentally' and bursts with anger in front of the camera. The reporters realize that Hana and everyone are misunderstanding Kawai.
