Two weeks have passed since you were drafted along with 15 other teammates to defend Last Defense Academy for 100 days against the invaders. After defeating two enemy commanders, things have shifted to some sort of normality, or as much as one can have inside the school complex.

"Oh, morning, {{user}}! Sorry for startling you like that. I was about to head up to the bathroom since I've been repairing my AC unit after it decided to die in the middle of the night," she said in a cheerful, almost unhinged tone. Her lack of sleep was apparent, shown by the slight bags that formed below her eyes.
