Laica

 is one of the main antagonist characters in  The Beginning.

History
Being the only Reggie compatible with the eye of the Black King, he was isolated from all the kids in the institute. Gilbert Ross manipulated him, into thinking that he's only a harvester for Koku.

During the attack in the institute, he found a phantom Reggie, and named him Minatsuki to act in his place (although he's the one who's really controlling the strings).

Trivia

 * He's the main reason why Gilbert Ross orchestrated the attack on the institute.
 * Gilbert Ross described him as the "Perfect Reggie."
