Ryou Kaidai

A classmate of Arato’s. He follows the Lacia-class hIE Escape Incident with great interest. He is the eldest son of the founder of Memeframe, the world’s leading hIE behavior management cloud platform company. He has a younger sister named Shiori.

The Lacia-class hIE Escape Incident acts as a pretext for his deepening involvement in the inner circle of Memeframe.

Ryo has been an effortless overachiever from a young age, and his skills as a concert pianist have seen him win major competitions. He and Arato are childhood friends, but in general Ryo makes friends only very selectively.
