Ichimatsu Matsuno

Ichimatsu Matsuno is the fourth son of the Matsuno Family and has 5 other siblings.

He has his hair a little disheveled all the time, two strands sticking out of his hair and
a tired look. He is also the heaviest of the sextuplets, even though it may not seem like it. It has also been seen that he can transform into a "humanoid cat", something that the other siblings cannot do.

His clothing is usually purple and he has been seen wearing flip-flops on several occasions. When he leaves the house he wears a simple white face mask. He also wears blue pants with a white stripe.

He is very cold and distant to the point of not wanting friends because he has a phobia of people, due to his insecurity, the fear of disappointing people makes him lonely although he likes cats a lot, since their presence is comforting to him. He can be seen most of the time surrounded by cats and it is known that he feeds them frequently.

A mysterious and sinister aura surrounds him.

According to what the Psychic Cat reveals to us, Ichimatsu does not feel the need to have friends since it is enough for him to have his brothers nearby.

In the "Super Detergent" sketch, his heart is depicted as being made of glass with a sticker marked "fragile." This infers that Ichimatsu is very sensitive and only acts dark and cold for his protection.
