Шарс Лакруа

Charce is well-versed in biology and extremely curious about all living things. He's also an excellent cook.

Although he was born and raised in the Royal Quarter of Vixia, Charce abandoned his home and moved into Caird's dormitory a few days before the school trip to Planet Mcpa started, but he kept it a secret from everyone.

In the end of the anime, Charce was revealed to be the group's saboteur, attempting to kill Group B-5 after a mission issued to him by its original, the king of the Royal Quarter of Vixia, Noah Vix.
