"Is- Is he sleeping with a snake?" Izuna yelped, very, very quietly, so Tobirama was not forced to strangle him, only give him a dark glare and lean over the baby - still asleep, blessedly.

"A viper." Madara said tiredly, not lifting his head from the desk, where Tobirama suspected he was hoping he could hide from the paperwork stacked around him. "It was his mother's favourite summon and she babies him."

"Leave it be." Tobirama said sharply as Izuna drew a breath, flailing a little; he glanced over at the boys, Jiraiya sleeping in an open sprawl on his back as he so often did, Orochimaru curled up on his side with his feet tucked in, Jinkei's thick body coiled in and out around his limbs and letting him hug her close to his chest, her head tucked against his jugular.
