Ep. 9: Teruaki punishes students with points while Natsuko sacrifices Aimi to survive the final test.

Teruaki threatens Natsuko with negative points unless she returns their phones. She complies, but Teruaki assigns +1 to Nobuaki, -4 to Natsuko, and -1 to Aimi. Natsuko passes without breaking her hand. The penalty on Aimi was a test she requested to see if Natsuko would sacrifice a finger for her, mirroring Teruaki’s earlier actions, which Natsuko failed. After others pass, Aimi hesitates to break her hand to save both herself and Natsuko. Natsuko manipulates Aimi by recalling past favors, then tackles her and crushes Aimi’s right hand to ensure her own survival. Aimi defends Natsuko’s actions as fear, granting Natsuko +4 points and herself +1. Nobuaki urges unity, but Natsuko insists only one survivor remains, referencing previous King’s games. Teruaki is punished for Natsuko blocking his message while holding his phone and dies.
