What to Expect in Episode 15
Episode 14 ended with a preview pointing toward demon family relationships and daily life in the Demon World. Episode 15 builds on this direction by exploring the world of demons beyond the classroom walls at Babyls School.
The episode moves away from the festival preparations that filled the earlier episodes. Viewers will get a better look at how demon families operate. The previous episode revealed that a new student will join Babyls School in the next school year. This student has ties to one of Iruma’s teachers.
Given this setup, demon family structures will likely take center stage. Iruma continues to learn about demon society, and these family dynamics remain new and unfamiliar to him.
Naphula’s acceptance into the girls’ friend group also opens the door for more relaxed bonding moments. The new focus on demon families may connect to Naphula’s own background and explain why she acted nervous earlier.
Recap of Episode 14
Episode 14 showed Iruma settling deeper into life at Babyls while still chasing rank progress. He joined a rare tour through the teachers’ dormitory, a space usually off-limits to students.
During the tour, Iruma discovered that the staff shows an unexpected side of themselves. The faculty members live free from the strict rules of being teachers. Each person showed unique living styles, interests, and pastimes.
The group dinner took place after Iruma helped serve the meal. He watched the teachers bond over dinner and saw how much they worked beyond the classroom. Their dedication to helping others made Iruma think briefly about possibly becoming a teacher in the future. Kalego quickly shut that idea down and refused to discuss his own school days with Iruma.
Naphula received an invitation to join the girls for the evening. The episode also featured Kerori’s rehearsal room sitting empty, Eiko still missing, and the ranks continuing to move forward.
