Clotho captures a Level 10 Chemy for the Three Dark Sisters and subjects it to their creepy experiments, bringing them closer to completion of "something". Meanwhile, Kugimiya and Harima from the Alchemys Union arrive at the academy and warn the students that there may be a mole within their ranks. However before he begins investigating on who the possible mole is, he heavily criticizes Houtarou's fighting style as a Kamen Rider.
