Nobunaga has, he’s determined, been sent south to perish. Greenleaf is serene, beautiful, and utterly boring. With a few years before he can start his time at Azuchi’s academy and Oichi terrorizing the castle now that she’s mastered the art of running it makes sense that he would be sent somewhere to be productive. He wishes it were Owari. Owari is fun, and Nagahide could have joined him there.
Instead Tomori, Mamoru’s Druddigon, has been sent with Nobunaga for companionship and protection. As a statement, as well, even if that statement is lost outside dragon territories.
The classes are boring, the landscape is boring, and when he dies no one here will know to burn him so the afterlife will be boring.
He has almost taken to gnawing at his own limbs in frustration when an innocuous statement made by one of his classmates draws him into a conversation and finally, finally stirs excitement in him. It starts with a small group of four and rapidly expands beyond the class. Wrestling---the kind taught to Nobunaga by Yasuke, not the play fights his peers have experienced with their siblings---learned between classes.
It eventually gets discovered, as Nobunaga finds out one day while demonstrating on an older student how to properly pin someone. He might be in trouble since he’s told to meet with ( what was the term the Greenleaf school used? ) the headmaster. Though he certainly can’t fathom why he would be.
