Howl in the Ring

Sela and Leo are kidnapped by the Dethgalien Player Amigarudo to be in his "Battle Show" where two people enter, and only one can leave, and he chooses best friends because it entertains him. As they fight, Leo holds back as Sela is a woman, which upsets her, and reminds her of the last time they fought in a martial arts tournament in Zyuland.
