Plot
Timid and awkward accountant Casey is brutally attacked on the street by a motorcycle gang. He comes across a dōjō led by a charismatic man referred to as "Sensei" and, after taking a trial class, decides to learn karate for protection instead of purchasing a firearm. Despite his physical weakness, Casey's determination impresses Sensei and he is promoted to yellow belt at their next promotion ceremony, while Anna, the sole female student and children's class teacher of the dōjō, is secretly denied promotion to black belt by Sensei because she is female.
As Casey learns the dōjō's strange customs - its unbreakable set of rules and the praising of its powerful grandmaster, who is promoted as someone who developed a technique of punching through an opponent's skull with his index finger - he himself becomes more toxically masculine: looking at pornography at work, attacking his boss, and listening to loud, angry music.
