Saiyuki S01 E47 Guilty or Not Guilty – Reprimand

Goku single-handedly resists an attack of Homura's Royal Guards so his comrades can enter the tower to find Homura. The enemy uses an artifice called "Work of Repentance", forcing a person to remember past emotional hurts. Goku is stunned when he sees his mother-in-law crying in front of him.
