After a series of panty thefts in the female dorm of first-year students, Glenn is turned into a woman to find the culprit.
Tropes:
- Chick Magnet: Except for Viola, the entire dorm welcomes Glenn with open arms due to their admiration towards the hero of Alzano.
- "Eureka!" Moment: Glenn has this upon realizing that the only thing that can bypass his security magic to frame him is something ghost-like, which allows him to figure out that Viola's White Angel is the culprit.
- Foreshadowing:
- The first panty theft that transpires when Glenn moves into the dorm is when Viola supposedly fails at summoning her White Angel. It would later turn out that said angel is the culprit.
- During the story, Maria shows an insane amount of attraction toward Glenn regardless of his gender change or supposed crime. Volume 23 would fully showcase that the Pure Darkness, which Maria is an Apocalypse Maiden from, has a similar if not even more extreme obsession with Glenn.
- Frame-Up: This happens to Glenn in the climax due to Viola subconsciously influencing her White Angel to throw all the stolen panties into his room due to not wanting to believe that any of her dormmates could be the culprit.
- Gender Bender: Once again Glenn has a Forced Transformation into a woman. This time in order to investigate the female dorm and figure out the culprit behind the panty thefts.
- Here We Go Again!: The story ends with Glenn running away due to Viola and Celica once again trying to turn him into a woman so he can solve another incident at the female dorm.
- Implausible Deniability: Viola is very vehement when Glenn states that only a student staying in the dorm could be the culprit and that they need to search through all the students' rooms to find the culprit despite Glenn making a very sound and logical conclusion to this decision. She even has them search through Glenn's room first even though the thefts happened before he moved into the dorm, which makes it impossible for him to be the culprit.
- Inside Job: Glenn eventually concludes that there is no way a thief could break into the girl dormitory without activating any of the traps, which means the culprit has to be one of the students living there.
- Panty Thief: Viola's White Angel became this due to behaving to Viola's repressed desires.
- Refuge in Audacity: Glenn is able to stop the female students from attacking him by boldly declaring he will punch Viola for her arrogance and that the only thing she can do is use her Summon Magic. Naturally, this is only a bluff in order to prove his innocence and reveal the true culprit.
- True Companions: The students staying in the dorm are all very close with each other, which is why they (especially Viola) are in disbelief when Glenn is only able to theorize that one of them has to be the culprit of the panty thefts.
- Unprovoked Pervert Payback: The moment the pile of panties is seen in Glenn's room, the girls led by Viola immediately start attacking him under the belief that he is the culprit even though the thefts happened before he moved in to solve the case.
