Also known as: 悪松
A character that originally appeared in Osomatsu-San.
He is the Personification of the Matsuno brothers' latent evil. Because of the large quantity of said evil, his physical form is a large amorphous demon-like creature. He is the antithesis of Kamimatsu.
He is usually depicted in fanart in a more humanoid form, resembling a Matsuno with Red Eyes/sclera and Sharp Teeth.
