The burning passion in Hinoken's heart is nothing but a fizzle after his defeat to Netto, back in episode 1. He's decided to get his revenge on Netto by luring him into a trap... but none of his attacks throughout the city are drawing Netto's attention! That's because Netto is currently fueding with Meiru, who he teased after one of Hinoken's attacks effected her hair dryer and gave her an embarassing new doo. Eventually, Fireman gives Rockman's battle invite to Roll, but Roll... wanting to prove her strength, goes up against Fireman herself! English version title - Hot Tempers!
