Fairies' Christmas - S0.E9

Lucy's apartment becomes the venue for a Christmas party for some of her friends. But the celebration soon devolves into chaos as Erza forces the rest of the guild into playing the Guild Master's Game with her. Erza proves merciless as she orders her friends to perform embarrassing acts. Gray finally manages to avenge everybody and orders Erza to walk home naked at the end of the game. As she leaves the party, she runs into Jellal, who kindly covers her up and accompanies her home.
