Confession Under the Moon - S1.E12

Ayano is having trouble fighting, whilst Kazuma takes Ren and Ayumi from the cavern, exiting through the top. This causes the behemoth to be freed and Ren, Kazuma and Ayano begin the fight against it. Ayumi helps the team out as best she can and suppresses the powers of the behemoth, giving Kazuma, Ren and Ayano time to defeat it.
