Clear

Clear has an average build and is the third shortest of the main four (Aoba being the shortest, Noiz being the second-shortest). He has short, scruffy snow-white hair that sticks up in multiple places. When he takes off his gas mask, Aoba describes that Clear has a very handsome face, bearing pink eyes along with two small moles on the right side of his chin.

Clear's wardrobe consists of a white trench coat and a yellow scarf. Under his coat is a white button-up shirt, which is quite short and reveals a little of his abdomen, and gray pants. He wears white boots with black laces that reach up to his calves and white gloves. He is almost always seen holding his clear umbrella and owns two masks to hide his face: his trademark gas mask and a mask of a traditional Japanese woman.

Due to not being human, he's incredibly strong compared to the average person. Clear is able to take the harshest kinds of abuse which is made evident when he agrees to let gang members beat him instead of harming Aoba. He then got up without a problem, simply asking if they were done yet. The only people who can lay serious harm to Clear were his own brothers,α and α2, who were much more advanced models compared to him. Clear has also been shown to be able to fend off multiple gang members at once, even holding his own while fighting alongside Mink.

Clear is a very formal person. He speaks in a very polite manner, often using "desu/desu ka" at the end of his sentences and tagging on the "-san" honorific to everyone he meets. He uses the term "boku" to refer to himself, a form of "I" usually used by younger boys in Japan. Usually, he is extremely cheerful, rarely ever getting angry, and harbors a childish and energetic personality. His actions appear to be quite eccentric and odd (to which Mink, Noiz, Koujaku and Aoba make notes of), most likely because he seems to lack some basic common sense of the world.

Though usually happy, he does have his insecurities. Before his grandfather died, he told Clear never to take off his mask. This leads Clear to believing that Aoba would come to hate him once he sees his face. Clear is also shown to be very emotional and keeps his feelings and personal questions towards others to himself until he reaches his breaking point or becomes visibly angry. He's also very inquisitive about human life, often stumping Aoba when asked what the reason to being alive meant, as well as death.

Clear is known to enjoy singing, as he does it often. He sings what he calls the "Jellyfish Song"- a calm, entrancing serenade that is almost like a lullaby. It's revealed later to not just be a normal song, but also able to counter-attack "Dye Music"'s effects. Aoba often falls asleep to Clear's singing, noting that it's soft and puts his mind at ease, also getting rid of his painful headaches.
