恋哀DEATHゲーム (Ren'ai DEATH Game)

Background
恋哀DEATHゲーム talks about two friends who are in kind of a game. GUMI tells how it is inside, saying that everything started fast and it would completely change his life. She demonstrates many times in the song saying that your friend is very precious to her and does not want to lose him, but says he will not lose this game. In the end, she rebels and ends up killing his friend saying that he was a grinning demon hiding in a mask.

This song is featured in the album 13ROCK.
