Ai Chan (Full name: Self-Regulatory Unit A1) is a Honkai Impact 3rd character.
A gynoid guarding a Previous Era site/lab in Siberia, awakened by Theresa Apocalypse who came to investigate the Arctic Ocean island floating in the sky after the Second Eruption. Recognizing Theresa as an intruder, A1 battled her and attempted to self-destruct to kill her after failing in battle, but ran out of energy before she could and shut-down. Theresa recovered A1 and later connected her to the Schicksal Battleship Hyperion, turning her into its Artificial Intelligence system and losing her memories in the process.
Within the game she acts as your in-game AI guiding you through many different aspects of the game.
