Plot Summary:It was supposed to be just another day for a skater boy Akira, but as it turned out.... just not quite the usual. Little did he know he was stepping on a manhole registered under the shadowy, mysterious group called 'B-Class Cultural Heritage Association'. As a penalty for standing on the manhole, his life is under threat for the next 3 minutes. Still confused Akira skates away, through residential area from pouring gun shots. Could he survive this ridiculous but serious life-in-danger attacks for his longest 3 minutes ever in his life, and win a prize?
