Catherine/Backstory

Catherine is a medical professional who understands true pain and loneliness. This is why she wants to protect her friends from the suffering she felt before. When she met the commandant for the first time, it brought back some memories to her. But without a body, they seem to hardly matter anymore.

When she was still human, she completed the fundamental theoretical framework for space colonization, taking scientific development to a whole new level. Her knowledge of material properties is also immensely helpful in battle.
