Fairy-Tale Card

At full strength the Fairy-Tale Card is a bulky yokai whose form is a knot of black tendrils tipped with buds, those buds joined to four playing cards: one bearing a face, one an ear, one a mouth paired with a nose, and one an upturned eyeball. He communicates through the face card. When Saint-Germain wields the power, two extra cards surface, bringing the set to six.

Once Okarun, Rokuro, Unji, and Saint-Germain finally break him, all that grandeur collapses. He shrinks into a small head with a scruffy beard and a pair of spindly little legs, stripped of everything that made him fearsome.

The Fairy-Tale Card takes pride in Danmara as a marvelous gift crafted for the humans dropped into it, even fashioning parts of the realm out of sweets to meet what he assumed were their needs, though his understanding of people stops at the belief that candy alone sustains them. He shows a measure of patience, willing to keep a child player captive into old age while waiting to be freed.

Beneath that, he is purely self-serving. He felt no pity for the Old Man Player whose endless years drove him to the brink of suicide, refusing to let him go while he still seemed useful. To the Card, players are tools: kept only so long as they serve, released only once judged worthless, and even then valued as bait whose stories of Danmara might lure the next victim to the cursed trunk. He brushed aside Momo's plea to leave and leaned on manipulation to keep the delinquent players from wanting to go home.

The Fairy-Tale Card traces back to a European sorcerer who bound the world's evil into a set of Japanese playing cards and locked the resulting yokai inside a cursed trunk. Unable to shatter the seals himself, he conjured a realm within the Danmara and turned the trunk into a gateway that swallowed anyone who touched it, recruiting humans to do the freeing for him. After a boy he had trapped aged into an old man, the Card discarded him as useless the moment a girl arrived, a chain of events that eventually placed the trunk in Unji Zuma's hands. When Saint-Germain reached Earth, the Card struck a bargain, trading his power for the promise of release.

During the Danmara Arc, Unji destroys the final seal, fooled into thinking it would send him home, and the Card breaks loose. He seizes Unji and unleashes the full might of Umbrella Boy, blasting shockwaves that knock Momo out and battling Rokuro and Vega in midair. Okarun grounds him with a heater-fed tornado built from Rokuro's nanoskin, wins the second kintama, and downs him with a dropkick. The Card then merges with Unji's body to rocket out of the trunk, only to be hauled back as Rin uses Mai's gravity power to lift Danmara's captives free.

Out in the real world, he tries to dominate Rin, is shoved off by Mai, and silences her by vanishing her mouth, before Saint-Germain immobilizes the delinquents with talismans and confronts him. The Card learns the hard way that he can only fall when his cards are destroyed in pairs. Even mind control fails against Unji, who refuses to believe the lies spoken about his mother, and a joint strike from Okarun, Rokuro, Unji, and Saint-Germain obliterates the cards at last. Reduced to a feeble husk, he is cornered by Saint-Germain, who spares his life per their deal only to stab him with a small blade and steal his power, then probes him about the elusive Dandadan. As a fighter the Card relied on swinging his buds like clubs, blunt strikes strong enough to gouge surfaces.
