Asta Story

Asta is the Lead Researcher of the Space Station brims with enthusiastic curiosity and boasts unimaginable achievement in the field of astronomy. She is capable of taking on workloads meant for dozens of people with ease, including commanding and maintaining the Space Station.


Despite her outstanding work capabilities, she is completely incapable of looking after herself. This doesn’t bother her one bit, though; in fact, she even uses it as a point of pride and proof that she has distributed the workload to the Space Station’s staff reasonably.


“I manage the Space Station, and Arlan manages me. What’s wrong with that?”


It is then that people are reminded that Asta is a young lady of a distinguished family.
