Yoshizou Tada  

, 多田 吉蔵

An elderly man with an extensive pornography collection accumulated during his hospital stay advises Yūichi to pursue Rika if he has feelings for her, as regretting not doing so later may cause him pain. Tada, who lived a life of regret due to not pursuing the person he loved, passed on and bequeathed his pornography collection to Yūichi in his last will.
