Genkaku Cool Na Sensei Ga -

You want to see a chalkboard eraser float in slow motion while a teacher whispers atomic formulas.

Review: Genkaku Cool na Sensei ga – Style Over Substance, But What Style! Premise: The story follows a high school teacher who isn’t just “cool” in the traditional sense—he’s literally hallucinatory.
