Sabu and Ichi's Detective Stories (1981)

In Edo, a group of masked samurai stormed a seafood wholesaler, killing the head clerk and robbing the money. They then crossed paths with Ichi, a blind masseur and master swordman. However, upon recognizing his blindness, they decided to leave without confrontation. The next day, a woman known to Ichi and her samurai customer was found murdered at a brothel, leading to the wrongful apprehension of Ichi as the culprit. However, a few days later, when another couple was found murdered in a similar manner, Ichi was released. With his friend, they began their search for the real culprits.
