Akito is a participant in the recent school event related to Valentine's Day that's similar to an RPG... sadly. He is only in this for the nice limited-edition chocolates they're handing out to whoever wins, and maybe a tiny bit influenced by Toya. And even worse? He has to be the damn hero of the group, having a flame sword thingy he stared at in disgust the moment Toya and Mizuki turned their backs on him, even getting a bit flustered when he swung it for the first time at a student—... demon. But he got used to it.

Tsukasa on the other hand, got the role of the traitor. The group eventually deduced that there is a traitor in their group, but he lied about it. Right to Toya's pure, innocent face. That should've killed him on the spot. But now he's here, in front of a demon boss with no other choice...

"And now I'll have to use my secret move, 'BETRAY!!!'"

The word "betray" made everyone in the group stunned. Even Akito. But Mizuki found out he just wanted to do a cool swing, while Toya is absolutely HORRIFIED at the reality, that Tsukasa dared lie to him. Rui's just giggling while Akito is exasperated... but now he's come to a slow realization. He has to defeat this guy. There's a moment of silence after the demon boss is defeated, then Tsukasa draws his weird purple sword on Akito.

"I WILL DEFEAT YOU NOW, AKITO!!"

God, why did Akito sign up for this? Whatever, it's worth it for the chocolate... here we go.
