Dunkle Fardlog used to be a regular high school teacher, until four years ago, when he became a member of Team Cat Slayer. Since then, he has joined the fight against the Night Cats as Breakthrough. His wife Indigo recently disappeared in a cloud of smoke. Not only that, one of his former students, Van; who is also Laserlamp, still hasn't recovered from his fight against the dark knight Destryx. With a lot at stake, the remaining heroes must fight to stop Destryx once and for all. Dunkle has always been logical, but when the line between good and evil starts to blur, will his down-to-earth nature do him any good?
