Buttobi!! CPU 3

Akira had been putting money down for a computer for the last three years. Whenever a new model 9821 is on sale, he rushes to the shop only to discover that it has already been sold out within five minutes. A guy in an alley occurs to have the computer he was seeking for, and as he walks back to his house, he becomes discouraged. He is overjoyed and purchases the computer, only to discover that he has purchased a 2198, a super-advanced bio-mechanical computer lady called Mimi, instead of a 9821 computer.
