In a showdown with Black Vinegar Middle School's shadow gang leader, Teru, Mob sticks to his policy of nonviolence and refrains from using his powers - and gets knocked out! The fight seems over for Mob... but something then awakens in Mob, beyond the confines of his conscious mind! And in the aftermath, a new story develops with Ritsu, Mob's conflicted younger brother who enjoys the social success Mob desires... yet still longs for what Mob has that Ritsu lacks - psychic power!
