Funny / World Trigger

  • In general, all the duck faces, to the point of Memetic Mutation.
  • Kuga's troll faces
  • The disturbingly adorable piles of dead Osamus that tend to show up when discussing his combat ability (or lack thereof).
  • Character profiles at the end of each volumes are usually hilarious as Ashihara makes fun of every character, such as Yuuma's duck faces, Osamu's lack of character without his glasses, Kodera's overlapping character with Osamu's, Arafune's love for jumping off buildings, Suwa's cube, Hyuse's inability to sleep facing up due to his horns, etc.

Introduction Arc

Black Trigger Retrieval Arc

Border Enlistment Arc
  • Ai Kitora being happier than necessarily warranted upon confirming that it was Yuma and not Osamu who defeated the Neighbour that attacked their school.
  • Ai Kitora being very jealous that Osamu is Karasuma's pupil.
  • Chapter 34: Everyone's shocked reactions when Chika blows a hole clean through the base walls with a Training Trigger by accident.

Large-Scale Invasion Arc
  • Kasumi Mikumo, Osamu's mother, is so youthful looking, that even Karasawa mistook her to be Osamu's sister. Being told otherwise stuns him into silence.

B-Class Rank Battles Arc
  • Sakurako Taketomi, one of the commentators for the battle, reacts with sheer shock at Yuma's skill and Chika's power.
  • Tachikawa doing things captain-like by explaining the meaning of the team emblem to Yuiga.
  • Ninomiya making snowmen to kill time during round 4. It doubles as heartwarming moment, because the number of the snowmen indicates that he still considers Hatohara, who backstabbed the whole team, to be part of his team.
  • Enedorad watching Terminator-2 and getting hooked.

Fugitive Arc
  • Episode 56 has a scene where Satori suggests Kitora to wear a thong, complete with hand gestures. Kitora was obviously repulsed by the idea.
    • The guys' surprise to see Usami in a swimsuit, especially Xeno's blushing.
