第 15 集: 戰鬥中失去火焰控制，Rin 在對戰 Amaimon 時展現其秘密形態。

15

Ryuji manages to save Rin from the giant chuchi, showing a strong friendship between them. When Rin, Shiemi, Ryuji, Konekomaru and Renzo head back to camp with their peg lantern, they noticed that Izumo and Nemu Takara each returned with their own peg lanterns already. The camp is suddenly attacked by Amaimon with his behemoth familiar, but Shura creates a barrier to protect the Exwires from Amaimon. After Shura gives Kurikara back to Rin, Amaimon holds Shiemi hostage via a chuchi larva implanted in her neck, forcing Rin to fight. Ryuji, Konekomaru and Renzo leave the barrier to help Rin, but Amaimon easily defeats them. Having no option but to go full force against Amaimon, Rin is forced to reveal his secret by exposing his true form in front of his friends. As Yukio and Shura aid the others, who are astonished after learning the truth about him, Rin easily overpowers Amaimon. However, after Mephisto comes to retrieve Amaimon, Rin loses control of his flames and goes on a rampage, cracking Kurikara in the process. (Source: Wikipedia)
