The setting is a parallel world to the film “Mogura no Uta.”
They are members of the gang Bordeaux-gumi, and when one day, their leader Bordeaux is killed by an unknown attacker, the members decide to seek revenge. Choppino, one of the gang’s higher-ups, belligerently wants to attack every gang they suspect might be responsible. However, the other higher-up, Gnocchi, is against it.
From Gnocchi’s more thoughtful point of view, there’d be no meaning to taking action before they have clear information. This angers Choppino, who thinks that they have to do anything they can in the name of the leader who took such good care of them. The rift between the two leads to an explosive situation within the gang.
Though they were once comrades fighting for the same purpose, a dispute broke out in the group over the attack on Bordeaux.
It was decided that they’d have a duel at midnight on Christmas, in an underground parking lot in Shinjuku. They agreed that the losers would follow the lead of the winning side.
Choppino brings Grappa and Salami, who are feared and known by the names “Gold and Silver Wolf,” and heads for Shinjuku.
Gnocchi sets off for Shinjuku with his right-hand man, Chimney, and on the way they pick up his childhood friends and fellow gang members, Cherry and Bergamot. Together they make their way to the duel…
