High school students Mainosuke "Mai" Hitomi and Yuu kiss for the first time. Later that same day Mai is hit by a truck and killed. Her scientist father, Toshihiko Hitomi, uses a scan of her memories created before her death to construct an AI copy of her, named "Ai". Soccer, the CEO of the American tech company Digital Ware, wishes to awaken his own AI and sends an agent to shoot Toshihiko and steal his software, but Toshihiko sends Ai through the modem to safety before dying. Ai finds Yuu through a school computer terminal nicknamed "Icon" that has been enhanced by Satoshi Takanaka, Mai's genius half-brother with a terminal brain disease. Yuu transfers Ai to his laptop, through which she interacts with him and Mai's old friends, including Rika, who is jealous of Yuu's love for Ai. Soccer sends Satoshi and others to chase down Yuu and capture Ai.
