Two male leads + master and disciple, limited-time scene compilations and group action, flirtatious wolfdog younger gong vs. outwardly proper, inwardly S wolf king shou. Main CP: Cuchulainn × Sakumo. Side CP: Obito × Kakashi.

“Cuchulainn, let go! I'm your master!”

With both hands pinned, Hatake Sakumo was pressed onto the bed beneath Cuchulainn's towering frame, unable to move.

“Ha, master? The master who's been sleeping in his disciple's arms for ten years? Or the master who sneaks around with his disciple?”

Cuchulainn easily subdued the man's resistance. Desire to devour its prey swirled in his crimson eyes.

“Big brother, admit it. You like me too.”

…

A boy who was neither a Heroic Spirit nor quite human came across a white wolf in the woods. Their first meeting was a coincidence, but every encounter after that was the result of the boy's careful planning, one step at a time. The white wolf falling into his trap seemed inevitable…

…

A straightforward Hokage world. Heroic Spirits can be summoned, but Cuchulainn is the only one available. A story written to fill the void when you're out of reading material.

Theme: The boy captured the white wolf, but the white wolf tamed the boy, too.
