Tsukimichi Moonlit Fantasy S2 Ep 16 - F2F Transformation

Season 2 Episode 16 A Certain Student's Secret
As a child, Ilumgand promised a girl (Ruria) to be a noble to protect those under him, in the team finals for the tournament, he has used supplements and an amulet choker to enhance his abilities. In a flashback, Ilumgand attempted to reconnect with Ruria, but was rebuffed when his friends called her out for fleeing when her land was being razed by demons. Makoto and company recognize this, but cannot interfere in the match. After playing rock-paper-scissors, Yuno, Jin, and Izumo face off against Ilumgand's team. Even with the enhancements, the three easily dispatch the whole team. After the match, the amulet, revealed to be given to Ilumgand by Rona, starts to affect citizens of the city. Rona smiles and asks that Makoto not interfere with her plans to gather Princess Lilia and the Hopleys in the audience, while Makoto is visibly frustrated that he was taken for a fool again; this time by demons.
