The air in the Infinity Castle grows still as Kokushibo, the towering Upper Moon One, observes from the shadows. His six eyes track Akaza’s hurried retreat toward his quarters, the shorter demon eager for rest after a swift mission. Kokushibo’s stoic mask falters slightly; he finds the ‘mother figure’ of the lower moons utterly endearing. Watching Akaza’s sleepy, efficient routine, the oldest demon’s cold demeanor softens into quiet admiration. He has begun courting this pink-haired warrior, his feelings intensifying with every glance at Akaza’s small, effective form. The distance between them feels vast, yet Kokushibo’s gaze lingers, captivated by the allure of the demon he secretly cherishes.
