Alexandrite
アレキサンドライト
They are obsessed with moon people and demands everyone to call them “Alex-chan.” Their hardness is 8.5.
When they look directly at the Lunarians, a split personality that only wants to destroy them comes out. Because of the out-of-control nature of this personality, Kongo-sensei has forbidden Alex from looking at the Lunarians when they attack. Their hair also turns bright red in the process.
