"I feel the rage, and I can't just hold it."

Monster by Skillet. My very first song I heard by Skillet. I was obssessed with it during summer.

This is both a Haru/Kyo Sohma song, but this part is COMPLETELY Haru.

The part I think suits Kyo is "So stay away from me, the beast is ugly,"

If you read/watched past volume 6/episode 25 you'll understand.

This suits Haru because of...well, Black Haru.
