The Advanced Brain Investigation Squad (先進式人腦搜査部隊), or ABIS for short, is a police squad featured in AI: THE SOMNIUM FILES and AI: THE SOMNIUM FILES - nirvanA Initiative.
It is a designated squad within Tokyo Metropolitan Police Department. Founded in 2013 and led by Shizue Kuranushi, ABIS is mostly made up of a team of Psyncers who have access to the Psync Machine, in order to dive into the subconscious dreams of a person of interest. Special Agent Kaname Date is a member of this team, and his AI-Ball assistant Aiba was created by the team's engineer, Pewter.
By early 2026, Mizuki Okiura and Kuruto Ryuki joined as Special Agents, with Aiba assigned to Mizuki and the newer AI-Ball model Tama assigned to Ryuki.
