Artist known for his distinctive art style and surreal sense of humor. Typically depicted as a duck-like humanoid, though in FF14 contexts his avatar may be used instead; he also has a VTuber avatar for streaming use.
His most notable comics include Poptepipic, a story about two maladjusted girls doing random, odd things; a Touhou series where everyone seems to be reading too much into each other except for Chen who never says anything; an Idolmaster Cinderella Girls series which stars the unit Ankira; Honey Come Chatka!!, about the titular idol group as well as their most dedicated pair of super-fans; and 3LDKM, a story about an apartment that comes with a robot maid.
