Cubik Galois

A young boy with the title of 'Edison', who is often inventing various robotics. He is often more fascinated by mathematics as opposed to puzzles, though takes interest in Kaito after witnessing his Phi-Brain in action. At first, he appeared to be self-centered, however this resulted from him being too young to understand the full extent of some of his actions. Nonoha calls him "Q-chan", as a pun on his name, and he does not seem to have a problem with that.
