Jun Kamigamo

A boy who works at the cafe. Jun is pragmatic and sensible, and does not engage in Hajime's childishness and crudeness. Hajime often says that Jun is "not much of a man" because of Jun's feminine attributes, which extend from having a pretty face to having a mostly unexcitable personality. Jun does not like to be in uncomfortable positions and tries not to do anything against the norm. Jun is actually a girl but keeps dressing and addressing herself as a boy with only Kaja knowing her secret so far. She goes back in time with Kaja, only to be horrified by the experience. She says that she does not belong in the past and that she should never have gone there in the first place.

Over the course of the series, there have been many instances where she has been revealed to be a girl, but everyone does not notice thinking that Jun is simply a very girly boy.
