It was just a small thing, just a tiny nick he 'd given himself while shaving, so he hadn 't really given much thought to it when it happened. The collar of his robes was high enough to conceal his neck and his massive hair had always kept most of him hidden anyway, barely more than half of his face peeking out through the jungle of wild locks. When he left the house that morning the small cut was already out of his mind and he didn 't think about it again until he was standing across the room from Tobirama with his eyes locked in on the little red spot marring white skin just beside the man 's Adam 's apple.

'Cut yourself shaving? ' Izuna was saying, teasing his childhood rival-turned-friend as he usually did.

'Someone did, ' Tobirama replied. 'But it was not me. ' He continued to flip through the papers he was carrying without bothering to look up, unbothered by the implication that he could have been so clumsy as to mark his own skin.
