A Punishment Inspector (Kansatsu Shobunsha) ("Probationary Student" in the English dub) is a student in Fumizuki Academy who seems to have great trouble studying and is one of the worst students in the entire school. They're tasked with helping out teachers by doing grunt work. Their Summoned Beings are given the ability to interact with physical objects in order to accomplish that task which also gives them both an advantage and disadvantage in Summoner Test War. The teachers Summoned Beings also have this ability. However, the Inspector is also subject to feedback; if their Summoned Being gets hurt, so will they. Despite being referenced as a title given to students who have trouble studying, it is usually granted only after a serious breach of the school conduct.

Akihisa Yoshii is the only known Punishment Inspector known in the series.
