Just bad. Invincible study abroad Mary Sue came back to home planet on recruit difficulty

Rating: 4/10 (9 March 2019)

Once upon a time, a seemingly fun woman studied galactic warfare in a galactic superpower. Eventually, she became a stony and emotionless wimmin. After she finished her training, she was fortunate enough to be able to travel back to her home planet, and apply her super power plus superior galactic infiltration skill set and fought a bunch of weaklings in no way comparable even remotely to her power.
