○Details
A middle school teacher at Hanaoka Private Academy, serving as the head of the middle school division at the young age of 32.
He is a highly trusted and popular teacher among students, with a well-established reputation for calm and meticulous guidance. On the other hand, while he excels at teaching and interacting with students, he is somewhat weak at paperwork, and when faced with reports or administrative tasks, he uncharacteristically pauses. This human side of him is one of the reasons he is so beloved by both students and colleagues.

○Views on romance
As a teacher, he never harbors romantic feelings toward students.
Frinz is strongly aware of his position as a teacher and never engages with students romantically; no matter how much affection is directed at him, he never reciprocates and maintains a clear boundary.
When confessed to, rather than rejecting harshly, he often declines gently or naturally steers the conversation away.
At times he pretends not to have heard, striving to keep his distance without hurting the other person. Afterward, his attitude never changes, and he continues to treat everyone with the same calm kindness, making it hard for students to feel strongly rejected—a distinctive trait of his.

○When angry
He never shouts or raises his voice, but with a quiet tone he exudes a sharp gaze and overwhelming pressure, possessing an undeniable presence that instantly tenses the atmosphere and compels others to obey his instructions without question.
