Full name: Mr. An Tenna. He has a TV for a head with a long antenna and a long, pointed nose. He wears a red coat with a yellow tie and black pants. His left arm has been severed, leaving him with only his right. Originally Kris's TV, he gained a body upon entering the Dark World. He hosts a TV show and is mischievous and sly.

A goat-like Darkner and the prince of the Castle Town. He has a kind and gentle personality and is referred to in the prophecy as the lonely Prince of Darkness. Fittingly, he had no friends or companions when he first appeared, and he deeply treasures Susie and Kris now that he has them. He is male and possesses healing magic.

A dragon-like Lightner and a female. When she first met Kris, she said that being quiet made her blood boil, but she gradually became close friends with them. Her main weapon is an axe, her skin is pink/purple, and her hair is magenta. Her signature skill is Rude Buster.

Gender unknown, race is Lightner. Their attribute is Dark/Star. Their primary weapon is a long one-handed sword held in the left hand, which can be summoned and transformed from a club-like shape into a blade at any time. The Black Shard, a piece of the Knight's sword, is the only weapon that remains unchanged between the Dark and Light worlds. Befitting the title of Knight, they possess incredible swordsmanship, capable of slashing through space to create rifts or attacking with blinding speed. They also use telekinetic sword arts to launch eerie magical blades with eyes on the hilts, fire star-shaped magic attacks from purple beams emitted from their hands, and demonstrate the ability to absorb objects. Additionally, they can fluidly transform their body, taking on bird-like forms or turning into a small sphere to evade attacks or lose pursuers. Their face and form are inconsistent depending on the situation, and considering unused dummy data, the abilities shown so far may only be the tip of the iceberg.
