Description
Alisa Himegami assists Professor Iriya at Iriya Heavy Industries, a major EX-ARM universe technology corporation, supporting research into advanced cybernetic weapons called EX-ARMs.

She possesses dark red hair usually tied in a ponytail and distinctive aubergine-colored eyes. True to her scientific role, she consistently wears glasses and a lab coat, often paired with shorts.

A pivotal event sees Professor Iriya's consciousness forcibly hijack her body. This act completely suppresses Alisa's original personality, transforming her physical form into a vessel solely for Iriya's mind. The professor exploits this control to advance research goals and escape accountability following his original body's demise.

Post-possession, Alisa's own identity and agency remain fully suppressed. Her existence is defined entirely by her status as the host containing Iriya's consciousness.

Details regarding her family, personal history, or life before working with Professor Iriya are absent. Following the body takeover, her character experiences no further development or reversion.
