Eri Hizawa was a Japanese barber who lived in Onomichi during the 2010s. In 2016, Kazuma Kiryu visited her shop to ask Hizawa if she could share some of her newborn baby's milk with his own ward Haruto Sawamura. Hizawa agreed after Kiryu helped chase off the drunk yakuza Takehiro Tsubosaki, who had been urinating on a neighbor's wall.
