Revision 5

Infinite Trigger

"Infinite Trigger" appears in early Project Mugen materials as a title for the player character. The Captain is addressed as an Infinite Trigger investigator who deals with Chaos anomalies. Different outlets also use it as a general label for the protagonist.

Esper

Some descriptions of ANANTA use the word "Esper" for characters with supernatural abilities. Not every official post uses this term in English. It appears more consistently in Chinese and Japanese materials, where it refers to the playable characters and some NPCs who have powers.

Each Esper has a unique personal story arc tied to the fight against Chaos. Their abilities are what make them useful to the A.C.D..

Naming consistency

The terminology is not used consistently across all official English materials. "Infinite Trigger" is more common in early posts. "Esper" appears more in coverage of the game. "Captain" is the most common title for the player character in recent materials. This wiki uses whichever term a source originally used.
