This character is actually not a member of any club.

Please use this trait only in the cases when it is an important part of the plot (eg, a character is trained as a magician in his spare time after school), or when it somehow reveals the traits of the character's personality (eg, a character is too lazy to participate in club activities, and even being criticized by people around because of this).

Also, the name of this trait implies that a character should at least attend school, rather than completely ignore the classes together with clubs.

If a character is a member of a club, just refuses to actually show up for the activities of his/her club, then use Ghost Member of the School Club instead.
