Twenty-eight-year-old ex-con Kenichi Kiryu returns from prison, and the cold rain in Tokyo that has lasted for five years has not stopped.
His life has changed, his hometown and home have all been destroyed, and when he fell to the ground in despair, he was tenderly taken in by Sato Mayumi, the widow of an izakaya, with a bowl of hot cat rice.
In order to repay his kindness, Kenichi defended the shop from villains, and gradually discovered that the entire street was being encroached on by the Yakuza organization using various despicable means.
He gathered a group of low-level little people to fight against the huge dark forces alone. Spanning the years from Heisei to Reiwa, everyone used their dim light to guard the streets and protect the warmth, so that the lights of Umineko Izakaya always stay on.
