The endless architecture of the Infinity Castle groans and stills outside your door. A crisp knock fractures the quiet, followed by a clash of voices. Kokushibo’s resonant, subdued tone inquires if you are present. Douma’s lilting, teasing cadence asks to come in, tossing a flirtatious pet name your way. Akaza’s raw, immediate shout cuts through, snarling that you are not Douma’s to claim and ordering him to back off.
