Daiki Hakono

Daiki has round eyes, dark hair, and a nose shaped like a snout, and as a child he wore a bowl cut. The day his father gave him the cursed trunk for his birthday, he had on jeans and a collared shirt layered under a sweater with long sleeves.

A drawn-out stay in Danmara warped him into a gaunt old man sporting both a moustache and a beard, his limbs gone hairy and his shins bound in bandages. Having outgrown the clothes he arrived in, he made do with a tattered sleeveless top and underwear, plus the helmet every Danmara player wears. The curse drove the aging onward afterward, whitening and lengthening his hair, fusing his beard into a chest-reaching tangle, and shrinking his height. These days he wears a plain bucket hat above a varsity jacket stamped with a bold letter B.

Growing up, Daiki revered his father and dreamed of flying planes just as he did. Praise from classmates swelled his ego into outright conceit, and he sneered at anyone he judged beneath him, with his classmate Toru taking the worst of it.

Surviving the nightmare of Danmara left him dreading any return once he escaped. Watching Unji and Raiya labor selflessly to break his curse pushed him to confront how cruelly he had treated Toru, and he came to long for redemption, hoping to grow kinder and one day make the apology he owed.

In the Danmara Arc, Momo and Okarun reach an empty Unji Zuma residence just as a sword-swinging, half-dressed Daiki bursts in, chased by a gang. The two subdue him and hear his tale: a cursed trunk gifted on his fourth-grade birthday dragged him into Danmara, where he scraped by for years on sweets and evasion until a girl's touch sent him home. The gang's bid to throw him back inside goes wrong when Momo brushes the diorama and is pulled in, kicking off the rescue. Once the realm's final boss falls, Okarun gathers Turbo Granny, Rin, and Mai to haul everyone out, with Daiki cheering Rin on. The freed Fairy-Tale Card starts possessing the teens, and Daiki helps shield Rin until Okarun, Saint-Germain, Rokuro, and Masamichi Vega put it down; afterward the group visits the hospitalized Unji.

During the Kozuka Knives Arc, Unji reveals a startlingly aged Daiki to Okarun, blaming the runaway aging on the Danmara ordeal. Vega had located the parents, but they brushed off the reunion as a sick joke, since their boy had been missing only four years. Touched, Momo brings him home, and Seiko agrees to study him, suspecting the same curse that grips Momo. In the Typhoon Human Arc his decline accelerates aboard a flight to Shimane as those near him begin forgetting Momo. When the Typhoon Human strikes the plane, Daiki recalls his pilot father drilling him on flight simulators; resolving to atone and to live as honorably as Unji and Raiya modeled, he seizes the controls and, guided by Bamora's coordinates, lands the aircraft safely at Izumo. In the Shimane Arc, the local priests strip the curses from both him and Unji. By the Six Curses Arc, restored to his true age, Daiki is brought by Vega to his parents and embraces them four years after he vanished, the tearful reunion airing on TV to Unji's quiet relief.
