  Summary

  Kalego sees Momonoki in a bar and learns that there's a demon that she loves and that she went on a blind date to move on from him. Raim describes Momonoki's crush as 'Mr. Cactus'; the name sticks, and Kalego decides to show Momonoki that life is so much better without Mr. Cactus.

  Summary

  Being a teacher at Babyls is 10% grading papers and 90% preventing a faculty-wide civil war. Being a teacher at Babyls means 24/7 chaos, a group chat full of insults, and a very real risk of being harrassed by everyone else. But God help the bureaucrat who tries to touch their students.

  TD;LR
  The Behind the Scenes of the Babyls teacher. A collection of stories about why the Babyls teachers are actually more unhinged than the students.

  Summary

  The Abnormal Class start putting Post-it notes (Sticky notes) on students and teachers as a prank. Somehow it escalates and everyone joins in. Kalego is not okay with this. And no one knows the culprits,

  I'm horrible at summaries :(
