He ends most of his sentences with "~nomi."
Shut has pale blonde hair, green eyes with blue makeup underneath, blue lipstick, and wears a white hat with blue roses and feather on the side. He also wears a suit with flaring sleeves and white ruffles, and also blue fishnet stockings and long boots. He wears a lock similar to Close's on his neck like a brooch. Additionally, he is usually always seen carrying a blue rose.
In his beast form, he resembles a large lynx-like creature with light yellow fur and red eyes with dark blue markings under them.
In episode 50, he now wears a bright blue suit and shorts with a ruffly white shirt underneath. He also wears black fishnet stocking and heels. His hair is now in a bun and his makeup is now the same as in episode 33. He now wears Lock, who is now a black and yellow-striped scarf.
Shut adores everything that is beautiful. He is a bit of a narcissist and also pompous. He likes presenting in a feminine way. Unlike Close and Lock, he seems more easily scared, and this is shown on various occasions; when Twilight is defeated and turns back into Towa, he acts horrified and shocked as if something very tragic had happened. When Lock later powers up and resorts to more dastardly and sinister plans, he cowers in fear.
Like the rest of the Three Musketeers, he can trap people into a gate of desperation to create Zetsuborgs by saying "Shut Your Dream!". In episode 20, it is shown that he can fire lasers from his rose. He can also slash through anything with his claw-like nails. To trap people in the gate of desperation, he says "Shut Your Dream!" (シャット・ユア・ドリーム！?).
Twilight - When he first sees Twilight, he seems to be charmed by her beauty, to the point in which he feels jealous when she powers up Lock instead of him. He is always seen blushing or admiring her when he is around her.
After Twilight is purified, Shut becomes devastated, and in episode 25, he learns that she now goes under the name "Akagi Towa" and is also Cure Scarlet. Though he still finds her beautiful, at the same time, he wants to defeat her.
Lock - At first, Shut thinks of Lock as an annoying kid who just gets in his way, but as the episodes progress, and Lock becomes more powerful, Shut begins to be more afraid of him and sees him a lot differently.
Miss Shamour - Shut seems to have a good deal of respect for her as she was the first to show any kindness towards him, first by helping him with his make up and then by giving him a scarf to keep him warm after he leaves on his own. This seems to be the influence of his turning as he is seen wearing the scarf when he returns to help the Pretty Cure.
Shut's voice actor, Hino Satoshi, has participated in an image song for the character he voices. This duet is only sung with Madono Mitsuaki, who voices Close, and Kaida Yuki, who voices Lock.
- Perfect Black (Along with Madono Mitsuaki and Kaida Yuki)
- Like the other members of the Three Musketeers, his name refers to sealing something away.
