Unknown. Ranfon has never been seen carrying anything that could be his Zanpakutou's Sealed State, and the Shikai lantern just appears in his hand when he says the release command.
When the release command "Burn brightly" is said, a lantern appears in Ranfon's hand.
The lantern can produce an unlimited amount of fire in bursts.
- Ember Shake: By shaking the lantern, Ranfon can send little fireballs the size of golf balls flying out in every direction, littering the area with small fireballs.
- Flamethrower: By blowing on the lantern, Ranfon can make fire shoot out of it in a spray-like stream.
- Spitfire: By blowing little puffs of breath in the lantern, fireballs can be shot out.
- Heat Wave: By swinging the lantern through the air in front of him, Ranfon can send a wave of fire shooting out a few feet in front of him.
- Comforting Warmth: By releasing a soothing warmth from the lantern, Ranfon can heal light wounds.
- Cauterize: By blowing a small burst of fire from the lantern, Ranfon can burn moderate wounds shut.
Not yet achieved.
The Zanpakutou's spirit takes the form of a floating ball of fire.
