In 2001, Masumi Arakawa persuades Ichiban Kasuga
to confess to a murder that his captain, Jo Sawashiro,
allegedly committed, to protect the latter's reputation.
Kasuga, feeling indebted to Arakawa, agrees to shoulder
the blame for the crime. 18 years later, Kasuga is released
from jail but learns from police officer Koichi Adachi that
the Tojo Clan has perished, while Kamurocho has become
the
territory of its rival, the Omi Alliance. Adachi also
informs
Kasuga that Arakawa was responsible as he
betrayed the clan
to join the Omi, while his son Masato,
whom Kasuga once
chauffeured, has died due to his
deteriorating health.
Seeking to expose the truth together,
they crash an Omi
Alliance meeting held by Arakawa.
Adachi is arrested for
trespassing whilst Kasuga is shot by
Arakawa.
