Nagisa

Nagisa (ナギサ) is a homeroom teacher of Class 1-A. He teaches social studies.

Appearance
According to the Houkago Shounen Hanako-kun spin-off, Nagisa holds an uncanny resemblance to Misaki, who was the teacher rumored to have passed away after falling off the stairs. Yako is deeply intrigued by the similarity, and hesitates to meet him despite being mistaken for a civet by Nagisa when he witnessed her in her fox form.

The two share the same-styled dark hair, but Nagisa's eyes are darker than Misaki's copper ones. He wears a red-and-blue athletics jacket over his formal wear of a white dress shirt and green tie. In addition, he has a faint stubble growing on his chin.

Personality
Nagisa appears frequently, though he becomes more of a background character as the manga progresses. He attends to his duty of teaching his students and doing career counseling appointments, as seen in Misaki Stairs arc when he calls Aoi over.

Abilities
Although he looks distinctly similar to Misaki, he doesn't appear to have share any memories or affiliations with supernaturals.
