After Headmaster Delbrand flew into space aiming to join the ongoing space battle, just as ordered, Emery went into action and quickly gathered all the spirit souls of the dead magus.
He collected the spirit soul of the Full Moon female magus, the Half Moons, and seven out of the eight Crescent Moons. As for the humans', he got none even though he had tried hard to find them.
It was actually common knowledge that Crescent Moon human magus tended to have a lower chance of having its spirit soul intact after death. This was very different compared to the elves; a fact that some parties used to prove the argument that the elves were a race that was more advanced than humans.
