A B-rank member of the Mage’s Guild, holding the ranks of Fire Saint Mage and Water Saint Mage.
He is a middle-aged man with noticeably receding hairline, appearing rather neurotic and always seems busy.
He wrote a letter of recommendation for Rudeus to become a special student at the magic university, earning him respect as someone who can provide valuable opinions to Rudeus at the university.
He was Roxy’s mentor and at the time, he had a strong desire for recognition. He became jealous of Roxy when she surpassed him, and Roxy, proud of mastering Water Saint-level magic, caused a rift between them.
When they reunited after some time, they both extended apologies and reconciled. Jinus welcomed Roxy as a teacher at the magic university.
Cliff regards Jinus as diligent, understanding, fair, and possessing a strong sense of justice.
Since he became vice-principal, it is said that racial discrimination among the faculty has significantly decreased.
