Ikariya

イカリヤ

A robotic squid from Kazuya's Doraemon Research Project, it is primitive compared to the cyberdolls. Rena has a fondness for Ikariya and takes it with her wherever she goes. It is probable that Ikariya may be the prototype for Kazuya's AI project, which eventually becomes the Maid Program, the core OS of all Cyberdolls. Kazuya makes periodic upgrades to Ikariya throughout the anime. With those upgrades, Ikariya gains his own personality.
