Aiba

AI-Ball, also known as Aiba (アイボゥ, Aibo), is the second protagonist featured in AI: The Somnium Files and a character featured in the Lemniscate YouTube series. She is an artificial intelligence that resides within Kaname Date's left artificial eye. Together with Date, she works for the Tokyo Metropolitan Police Department to solve crimes and catch criminals, in particular, the culprit of the Cyclops Serial Killings. She has the ability to delve into a person's Somnium and extract testimonies and memories from various persons of interest. She is cold and calculating but has personality when it comes to Date; she disapproves of many of Date's habits, be them chocolate collecting or cabaret clubs, to the point of vocally teasing him, but overall trusts him. However, she has shown the ability to stand up to Date and voice her opinion, as well as her own feelings regarding investigations. She's also something of a nerd, wanting to make dramatic entrances parodying Terminator and looking into Ota's otaku hobbies for "research."
