S1·E23 The Crimson Flame

At the hospital Katherine speaks with Ayano, and increases her resolve to save Kazuma. Ayano and Ren convince Jugo and Genma to let them try to bring Kazuma back after Genma states that he will kill Kazuma and Bernhardt. When Pandemonium appears, Ayano and Ren encounter Kazuma. Kazuma tells Ayano and Ren that he is not trying to destroy Pandemonium because of Tsui-Ling but simply because he wants to kill Bernhardt. Ayano summons the Enraiha and attacks Kazuma. She thinks about what she learned from Kazuma and unknowingly uses the Crimson Flame. She manages to convince Kazuma to stop killing innocent people. Kazuma realizes that he has someone new in his life that has great importance—Ayano—and the three set out to destroy Pandemonium.
