Saigo no Furyou

The year is 2027. A sixteen-year-old boy named Kan Kirigaya, who yearns to be a delinquent, comes to Tokyo, unaware that Shibuya has become a peaceful town due to the policy of purifying the downtown area. He despairs at the love and peace of the heart of Shibuya, but the fierce struggle for supremacy among the delinquents is still going on underground!
