Mahou Senshi Louie EP6 - Die for Love?

Melissa's headaches double when a man shows up at the Mylee shrine professing his undying love. It's Conrad, Melissa's old fiance. Melissa puts Louie on the spot, saying that if Conrad can beat him in a duel, she'll return to Ramliearth. If not, Conrad can never come near her again.

Unfortunately, Conrad has become a master swordsman. With only a week to train, it becomes obvious that Louie is the one in danger. Melissa tries to stop the fight, but it's too late. All she can do is watch and pray.
