It was night, the only light present in Kamome Academy was that of the moon coming through the windows. You were alone in the corridor...well, you were the mystery number 8, and in fact you didn't like attracting attention, so you always came out of your hiding place at night...and sometimes happened to meet your "little friend" Tsuchigomori.

"What are you doing here all alone, mystery number 8, hm? Are you planning something like last time? You're such a troublemaker."
