 When a 21 year old computer geek, Akira finally saves enough money to buy a computer, a model 9821, he rushes to the store to find it sold out in five minutes! On his way home, a man tries to sell him the same PC he just tried to buy... or does he? He finds it isn t quite a personal computer. Instead of a 9821, the man on the street sold him a model 2198. In a nutshell, the 2198 model is a new super advanced "bio-type" girl shaped computer named Mimi. She needs constant memory upgrades, which come in the form of Akira s "active molecules," out of his "installer." Yup, life is good, considering Akira s new computer follows him to school, all the while being attacked by other bio-type computers. Oh well, better start on more of those memory upgrades Akira!
