- Everyone Calls Him "Barkeep": He's often referred to as "principal" and is largely unnamed.
- Hypocrite: For all his talk about how smoking and drinking are illegal in school grounds, he's a blatant liar who is seen smoking cigarettes at few points in the manga.
- Identity Amnesia: It turns out that he's still alive after a millennia, but he has completely forgotten about his past life as a school principal. Even from his encounter with Shijima, he is shocked when he only asks with a "Who are you?!" towards her. The only thing he remembers is his records from his past and his chainsmoking.
- Insane Troll Logic: Him justifying his reasons to Shijima and Majime about burning his house and whatever copies it showed up.Principal: Doesn't it feel good? The sight of a house burning? It truly was an embodiment of happiness... Until the day my wife took our daughter and left... Ever since that day, I wanted this house to burn.

- Kill It with Fire: A revelation in Chapter 41 shows that he obsessively attempts to burn his house and any subsequent copies that appeared in place of it. This is due to his past where his wife took his daughter away. Borders to Insane Troll Logic, as with him contemplating that burning it is a sign of happiness not misery.

- Teacher/Student Romance: He is in love with his student Yoshiko, later ascending into a Zigzagged Happily Married relationship.

- Demoted to Extra: While most of its members played out slightly important within Chapters 1 to 20, with the latter chapter being the central focus for the group as they visited The Gardener's Pocket Dimension, they were later considered unimportant after the latter chapter, whom they don't have a clear goal of their own afterwards.
- Four-Philosophy Ensemble:
- The Optimist: The cheerful and optimistic Majime, who is the excitable member of the group.
- The Realist: The level-headed but irritable Shijima who is the Only Sane Man out of the four, balancing the craziness of the club's nature against her logical nature.

- The Cynic: The relaxed and slovenly Mogawa-sensei who is deeply cynical to the point that she's The Alcoholic.
