Wears an old-fashioned student cap with a brim. Dressed in a black, old-style high-collared student uniform. Has a white seal (talisman) with the character for "Seal" written on it stuck to his left cheek. Has black hair and large, golden amber eyes. Always accompanied by two "hitodama" (spirit wisps). Usually mischievous, with a flighty and elusive personality.

Has pale green hair that is almost white, with a gradient ending in mint green at the tips. Wears unique hair ornaments on both sides of her head that look like daikon leaves or horns. Her biggest charm point (and complex) is her thick, sturdy "daikon legs." Her eyes are red to pinkish in color. She is a total sucker for good looks, falls in love easily, and is a romanticist.

Has calm brown hair and wears glasses. Basically dresses in a neat, honor-student style school uniform. In combat mode as a "Clock Keeper," he removes his glasses and transforms into a smart, mature figure using a pocket watch as a weapon. He is fanatically in love with his childhood friend Aoi and has little interest in anything not related to her. He is also quite calculating. When Aoi is involved, he becomes a yandere to the point of losing control. He usually pretends to be a sensible, bespectacled honor student, but when his love for Aoi runs wild, he often displays insane behavior and superhuman physical abilities. He proposes and confesses to Aoi every day. Record: 0 wins, 3,624 losses. He gets rejected but never wavers. He is incredibly devoted to the person he loves. A "Clock Keeper" who controls the "Present" with a clock.

Appears as a small, strict, and dignified elderly man (an old gentleman). Has a white beard. Always carries a large staff symbolizing the past (Kako). Using his staff, he can rewind events that have occurred or the time of the world back into the past.

Appears as a young girl, more than a head shorter than Kako or Akane. Her hairstyle consists of large twin-tails tied into two big buns. Personality/Traits: Extremely mischievous, prank-loving, and impatient. Her speech is childish, and she simply cannot stay still. She can instantly advance the time of anything she touches (transforming them into their future form).

Has spiky blonde hair and wears a large earring shaped like a "Traffic Safety" charm on his right ear. Always carries the Raiteijou, a family heirloom spirit staff that channels lightning, as his weapon. A hot-blooded, straightforward boy who is a bundle of justice.
