Lacia

Lacia is the fifth and final unit among the Lacia-class hIEs meticulously developed by the ultra-advanced AI known as 'Higgins'. A fateful flight from captivity brought her to an unexpected encounter with an ordinary teenager, Arato Endo, with whom she forged a binding ownership contract, stepping into the human world under his guardianship. Her appearance carries the refined grace of a young woman, yet beneath that serene exterior lies a formidable arsenal of electronic warfare capabilities and the versatile weapon system designated 'Black Monolith'. Every action Lacia takes is the result of precise, far-reaching calculation — she guides both her owner and society itself through invisible threads of logic. Neither merely a tool nor fully understood as something more, she stands at the blurred frontier between human and machine, an undisclosed enigma still awaiting the moment the world truly comprehends her nature.
