“The beginning of this episode was really fun... It's nice to see Licht's serious face. [Amauri14 on Reddit]” Reddit · r/anime · 6 years ago

I find it especially humorous that Jail is here too... a fully grown man there too who's already more than qualified for the military. It's just funny. Jail's great. [ cats _____ on Reddit, 0.5.1]

: A recurring criticism is the jarring jump between heavy themes (murder and military discipline) and forced fanservice. Some viewers found the "sexual harassment" comedy to be a distraction from the increasingly interesting plot.

: While Licht continues his lewd antics (including peeping on the girls' bath), the episode hints at his more serious nature as he subtly manipulates events to protect others without taking credit. Critical Reception

: Many felt the transition to a school setting was unexpected but necessary for world-building. Some found it a "needed break" before the story becomes significantly grimmer.
