"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!"--Provided by publisher.
