New Kids War Episode 17

Kaori gets a call from Kojima Rina at the park, saying she wants to die. She rushes over with Hana, but Rina is not there. The next morning, Kaori asks Rina what happened, but Rina does not explain it clearly. Later, Rina shows Kaori a notebook with a razor stuck in it, as well as her books and notebooks that have been thrown away in the trash, and complains that she is being bullied, but does not say who is responsible. Kaori asks Hana to look into it, but she still does not know. Meanwhile, Hana gets into a fight with two bad 6th graders who are skateboarding down the hallway, but vice principal Nishikawa and Kikue see this and scold Hana. Daichi comes in and protects Hana, and angrily protests to Nishikawa and Kikue. (Source: Japanese = hicbc.com || Translation = mario121 at MyDramaList)
