The Investigation Team are the heroic faction in Persona 4, and the one which all of the main protagonists belong to. They are a group dedicated to investigating the phenomena of the Midnight Channel and stopping the murder cases in Yasoinaba. The members have little faith in the conventional law enforcement system because they feel the police are inept, and are convinced that revealing Midnight Channel to the police could exacerbate things and render IT members unable to catch the murderer. The Investigation Team also represents the Fool Arcana Social Link. In addition, much like how SEES eventually becomes the Nyx Annihilation Team, the Investigation Team eventually becomes known as The Seekers of Truth if the player chooses to continue searching for the real culprit, at which point it changes to represent the Judgement Arcana Social Link.
The members, arranged chronologically in the order of joining, is as follows:
- The Protagonist: Founder/Field Leader
- Yosuke Hanamura: Founder/Second-in-command
- Chie Satonaka: Founder
- Yukiko Amagi: Member
- Kanji Tatsumi: Member
- Teddie: Support/Member
- It should be noted that while Teddie aided the Protagonist, Chie, and Yosuke even before the Investigation Team was founded, he did not join the Investigation Team until later.
- Rise Kujikawa: Support
- Naoto Shirogane: Member
IT members often hang out with these people, but they are not considered to be official members.
- Nanako Dojima
- Naoto's theme in Persona 4: Arena, Seeker of Truth, is named after the group's Judgement Arcana social link of the same name.
