Tsunade smiles, thin and bare with fury. “Sensei,” she says, and steps forward. It seems for a moment like Sarutobi is going to try to hug her, but she lifts her chin, meets his eyes, and he falters in the face of her expression. Falters, stops, but Tsunade doesn’t. She reaches up, pulls the hat from Sarutobi's head, and says, “I'm deposing you, sensei. You have an hour to leave the office or I’ll be forced to make you.”
