Buttobi!! CPU

For three years Akira has been saving up for a computer. When a model 9821 goes on sale he runs to the store only to find it sold out in five minutes. Discouraged, walking home he discovers a man in an alley who happens to have the computer he was looking for. Excited he buys the computer and runs home only to find that he didn’t purchase a 9821 but a 2198, a super advanced biomechanical computer girl named Mimi.
