The Anime Lad
Sistine studies diligently at a prestigious magical academy. Her new part-time instructor, Glenn, writes self-study on the board and appears committed to napping through employment. She challenges his fitness for the job directly. Glenn's poor first impression is comprehensive. The students have received a classroom dispute instead of a lesson, with no refund information available.
Super Eyepatch Fox
At an elite magic academy, serious student Sistine receives Glenn as her temporary instructor. He avoids lessons and writes self-study on the board, losing the class almost immediately. Sistine refuses to let the insult pass quietly. The opening builds its school comedy around an instructor who will not teach and a student determined to hold him accountable.
Gigguku
Glenn walks into a magic classroom, writes self-study, and somehow gets worse from there! Sistine's fury is completely earned. She came ready to learn and got a substitute treating employment like an inconvenient rumor. Their clash gives the school setup immediate heat because she refuses to laugh off his contempt. The classroom may be stalled, but the argument is moving at full speed.
Father's Basement
Glenn's laziness is pushed so hard that the opening can feel like wasted class time by design. The costume design also caters to the audience before the students. Sistine is the useful counterweight. Her diligence gives his behavior a real target, and her open anger prevents the story from pretending that a negligent instructor is automatically charming. The setup earns friction, not trust.
