When he was in elementary school, Airu first realized the feelings he held toward Kizuki. When he entered middle school, fearing the sense of being different from his schoolmates, Airu refused to acknowledge who he really was deep down inside, and began roaming the midnight streets. However, with the help of Touya, who patched up Airu's injuries, let him stay the night at his apartment, and gave him the support he needed, Airu affirms the love he feels for Kizuki. As for Kizuki and the others...they're desperately searching for Airu!
