Chirijiri Yuku no

Shio Kuno, who is half human and half alien, has a "glitch" that causes his body to turn into a gel-like mass when he gets lustful. He enjoys attracting girls who gather because of his novelty, but one day, his parents are worried about Shio, who is only interested in splattering, and transfer him to a boarding school for boys. At the moment when Minato Souma, the class representative who was assigned to take care of Shio, hugs him, Shio somehow splatters...!?
