Despite being a prodigious physics talent in his teens, Junichirou Kagami's passion for science fizzled out after college. He became idle, devoting his time to blogging about and collecting anime as a NEET. With the excuse of an illness, he refused to do anything he didn't feel like doing. His younger sister secured him a teaching job in his old high school to try and steer him towards productivity. Junichirou made an eccentric instructor but his students loved him nonetheless. A student's bullying ordeal led to Junichirou rediscovering his love for teaching. The question now is whether he'll stick with his nontraditional profession, return to physics, or relapse into his former ways.
