Aigis

A character who appears in Seasons OS1, and OS2 and Season 3 in Cope Island.

The Heartless Armed Angel
Aigis is an Anti-Shadow Suppression Weapon developed by the Kirijo Group. The lastest gen one, and the only one left, she is the culmination of all other units as she possesses all of their data. Despite having no reproductive functions, just being near Door-kun is enough to make her have a cyber-orgasm.

Off-Season 1
In this timeline, the ayys wiped out everyone before she could be activated and she was left inactive until she was found by The Final Resistance, promptly joining them regarding the aliens as "Shadows".

Off-Season 2
Aigis came to Cope Island along Door-kun to "protect him" in their room at night.
