Ichima

She is a Dream Demon who tried to get Minato as her vessel.

Appearance
She has long black hair and a white hakama with the sleeves woven together and black pants. Her pupils are shaped as a spiral when angry.

Personality
Although she acts like a yandere toward Minato in her first appearance, her true personality is more of tsundere after she appears again getting angry at Minato and her friends but then apologizing for it then getting mad again.

Plot
She becomes Minato's dream demon and makes a vow with Minato stating that she cannot make friends. After Merry and Yumeji play Kick the Can with her, they are invited to her world in a daydream. Knowing that Minato made friends, she attempts to attack her, but is defeated by Merry.

As of the latest chapter, she has appeared again this time without the need of a vessel. She still claims to be Minato's only friend despite the fact Minato no longer has any memory of her, after getting angry at Minato's new friends she takes her leave but says she will be back.

In the latest chapter, she tells Yumeji that she can't reveal who she really is to Minato and how she knows her until Minato remembers who she is on her own.

Powers & Abilities
She has the power to stretch her arms and summon and drop giant kokeshi statues.

When Yumeji uses her ability as a Lucid Gadget, he yells out "Loneliness!" and drops a giant pillar. This power is used against Maestro Achelnote.

Trivia
