The value of an object is determined by the form and function that humans give to it.

Lacia (レイシア) is the main female protagonist. She is an android equipped with a bullet-stopping device. Lacia becomes Arato's property after saving his life from hijacked electronics.

She was later revealed to be the world's 40th Super Intelligent AI and successor of Higgins.


Lacia has lavender hair and eyes. Her standard outfit includes stilettos, which she uses in combat. She wields a cannon shaped like a coffin that's much bigger than she is.


After spending enough time with Arato and receiving his Love Confession, she not only does physical harm towards herself by her own volition by ripping out her contractor, but also remove any possibility for her to continue on without him as well. All without an ounce of regret.


A chance encounter brings the hIE Lacia face to face with Arato Endo, and she immediately forms a contract with him: Arato becomes her new owner. Shortly after this, she is signed up to a modelling agency by Arato’s younger sister Yuka and begins to work as a supermodel.

She is the fated heroine who propels the story. Lacia is one of a select band of special hIE who escape from the Tokyo research facility of Memeframe, the world’s leading hIE behaviour management cloud platform company. She is a Red Box, a being that mankind has yet to fully comprehend. She was developed by Higgins, an ultra-advanced artificial intelligence. She comes equipped with Black Monolith, a transforming device fitted with a powerful quantum computer.


Weapon: Her Black Monolith doubles as a cannon and shield.




  • Her hacking skills are less destructive than Snowdrop's and she specializes in turning herself and others invisible.
  • Regarding her relationship with Arato, she has stated that some of her functions aren't available to children under 18.
  • Of the five hIEs, she's the only one who's motives aren't ambiguous or destructive.
