Introduction
A cool guy with a suspicious vibe.
Sirop is a friend of Macaron, and he supported the creating of Pumpers. He often tries to flirt a boy who he is interested in, especially Greantea and Bluemount. That makes Bluemount's invectives, but Sirop never minds.
Sirop is not obsessed with balloons, but he likes them as fantasies. He also enjoys physical contacts of balloons. He is not afraid of popping.
