Does the village head of Arakawa Huanhuan Group have any other identities?

The manager of the deserted river bed, known as the village head, firmly claimed to be a river boy. Regardless of the eyes of outsiders, he organized Arakawa residents to live separately from them. He claimed to be 620 years old, with a height of 176cm and a weight of 85kg (including crustaceans). When the new residents of the village head come, they will be given new names and hold a welcome party. I seem to have known Xiao Shan since I was a child. Usually, he insists that he is a river boy. In fact, he is wearing plastic clothes (including exhaust fan and oxygen bottle, and the length of his hair can be changed by turning the disc on his head). Except Xiao Zhao, all the other residents think that he is a real riverside boy. According to seiyuu's dubbing, the person who solves the problem should be the village head. Therefore, the village head is unexpectedly a super big shot, but it is not the face of young people circulating on the Internet, but more like a middle-aged man with great power. My hobbies are sumo wrestling and collecting anal balls. He lied about going to Xiaoshan's home planet and receiving special training in the universe, so that Xiao Zhao and others could build formal villas at the bottom of the river and live a comfortable life. Things about love are as simple as small moves, and I have never found a feeling for P. Take in nuns and Maria, take care of the young heroine, and become the first residents of Arakawa.
