Hothead Tanaka Ryuunosuke is seen by many as a powerful cornerstone, secure in his identity and his ability. Yet every day, he wakes up to face an ongoing battle: a fight to resist his dark past, his bloody history, and his dangerous instincts. As Noya ultimately discovers, triggering the hidden cracks in his best friend's psyche can be detrimental… for everyone. T for violence.

Tanaka slowly began to realize that their small libero had somehow adopted a dangerous mindset. Over time, it was painfully clear that to the Guardian Deity, there was a very blurred line between acts of salvation and acts of sacrifice. The longer Noya treaded that line, nearing the perfection of an impossibly flawless receiver... the more he neared his own demise.
