Ep. 12: Kiyoshi's hallucinations lead to a tragic end involving Ryouta and Himiko
Kiyoshi suffers hallucinations and attacks Ryouta with homing-type BIMs, injuring his leg. Ryouta blames himself but, with Himiko's help, evades the assault until Kiyoshi flees in panic. Pursuing him, Ryouta attempts an apology, but Kiyoshi, overwhelmed by guilt for betraying them, commits suicide using a BIM while surrounded by Kimodo dragons. Ryouta mourns his death as Himiko retrieves his chips, and they return to their hideout. There, Himiko asks Ryouta to kill her to facilitate his escape, but he refuses. Ryouta recognizes Himiko from Btooom!, leading to an intimate moment where he promises to date her properly upon returning home. Meanwhile, employees from Tyrannos Japan depart for the island due to reported mechanical issues, with Tsuneaki Ida silently apologizing to Ryouta, suggesting he may have assisted them.
