Episode 2 is about skateboarding, Kenta learns how to do it. His pudgy classmate whose name remains unknown is impressed by his ability to ride up a ramp!
After learning that the skateboarding training at night is the reason why Kenta is sleeping through class, Machiko uses skateboards to teach physics in the gymnasium.
After the VP protests it (partly due to Machiko's tendency to show off her panties accidentally by trying athletic stunts) a Burglar breaks into her office and robs her.
Machiko and Kenta use skateboards to outrace the burglar down a steep hill and beat him up, returning her belongings and winning the VP's approval of the skateboarding.
