Souichi Negishi appears as an ordinary, introverted young man who adores flowers, strolls, and catchy tunes from the radio. Unbeknownst to many, he transforms into Krauzer II, the frontman of Japan's famed underground metal group, Detroit Metal City (DMC). Torn between his desire for a peaceful existence filled with Swedish pop melodies and heartfelt verses and the raucous, profanity-laden performances of DMC, Souichi grapples with his dual identity, showcasing a stark contrast in his demeanor when onstage with his band.
