It is shown that Tokaku's inability to kill came from her aunt, who followed her sister's wishes to not have Tokaku grow up to a killer like the rest of her bloodline. With Tokaku still locked in battle with Isuke, Haru attempts to escape from Shinya's violent mallet attacks on her own esteem. After receiving another message from Kaiba, Tokaku manages to stun Isuke with a taser hidden in her shoe and escape. However, she falls into a trap laid out by Isuke and is pushed off a bridge. Meanwhile, Haru is chased to the A/V room of the school, where Isuke uses a projector's light to cause Shinya to experience traumatic memories and knocks her out before turning her attention towards Haru. Tokaku, who had managed to survive her fall, finally comes to understands how her mother and aunt protected her with their lives and overcomes her hesitation, stopping Isuke and rescuing Haru. With both Isuke and Shinya defeated, the remaining classmate, Sumireko Hanabusa, prepares to make her move.
