AI: The Somnium Files Wiki

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 Date and Kuruto Ryuki joined as Special Agents, with Aiba assigned to Mizuki and the newer AI-Ball model Tama assigned to Ryuki.

History[]

ABIS was founded in 2013 after the finished version of the Psync Machine went live. Boss has been in charge since its inception. Shortly after ABIS was established, Pewter joined the organization, and Boss found and recruited Hayato Yagyu to join ABIS, and gave him a new identity: Kaname Date.
