Half a year after the «Death Gun» incident, Atsushi followed Kazuto and Asuna on their way to Asuna's house, until Kazuto noticed that he was following them. He presented himself and menaced Kazuto with a syringe of Succinylcholine and later stabbed him. Although he was stopped and captured by the police, he succeeded in hurting Kazuto severely.
