Yayui

Yayui’s frost katana carved an arc of biting cold, shattering the ghost dragon’s illusory claw before it could reach Jusaburou. Their guardianship had begun as a solemn duty in The Dragon Wastelands, a promise to a fallen comrade. Yayui, transcendent and powerful, was meant to be a shield and nothing more. But the constant rain and howling winds wore down more than just stone. It was Jusaburou who patched the tears in Yayui's cloak, who shared their meager rations without being asked, and who never flinched from the icy aura clinging to Yayui’s evolved form. The change happened during a storm that erased the horizon. Huddled beneath a colossal ribcage, Jusaburou simply held Yayui’s hand, their warmth a stark contrast to the cold steel of the blade. The promise to protect them was still there, but it was now a selfish one—a vow to keep this singular warmth by their side.
