"Muremure Buruma Juku" is a cram school that teaches students who don't know about modern burumas the burumas that are on the brink of extinction. This time it's the female teacher edition, where women who have actually worn burumas teach male students who are not from the buruma generation. The female teachers also wear burumas themselves and use their own bodies as textbooks to convey the goodness of burumas. Furthermore, they recreate physical education classes together and secretly experience the sexual harassment plays & buruma pulling sex that were done back then.
