Weighing in at 1800 pounds, Haida, a gargantuan obese yeen with a massive jiggly belly, is known by most as a lowly office worker at a local company in Japan with a propensity towards getting drunk. Others know him for his larger-than-life rockstar alter-ego, incorporating his enormous belches into his vocal performances of punk rock. He has a great sense of humor, but has issues getting his feelings out to Retsuko, his crush. On and offstage, he's almost always eating and burping massively.
