from ebookjapan: Nishiyama Mitoshi, 44 years old. He's a toy maker (or he would be, if he ever went to work). Now that he's an adult and a father, he possesses social status, intellect, and libido, but, like a kid, he is unwaveringly self-serving. That's this manga to the letter--full of foul, dirty jokes, business-themed gags, and toilet humor that both the kid and the adult in you can enjoy!
