Trivia
- This marks the debut of Othinus in a non-4koma manga series.
- Despite the events that turned Othinus small having occurred in late November, Touma's uniform is still the summer uniform instead. This would either indicate that the events of the manga occurred a year after the events of Othinus becoming small, or an oversight by the artist.
