Ch. 561I Examine Myself Three Times a Day / An Eye for an Eye, a Tooth for a Tooth
Amamiya Natsuki agreed to take Sayu with him on a late-night trip, but Kitagawa Marin arrived before Sayu could leave and offered to help him bathe. Sayu hid in the bathtub, leaving Natsuki sharing it with her while Marin washed his clothes and remained unaware.
- Sayu insisted on accompanying Amamiya Natsuki when he went to punish some wicked people, and he told her to meet him at eleven thirty.
- Sayu hid in the bathroom when Kitagawa Marin knocked, and Marin came in to check Natsuki's injured shoulder.
- Marin noticed that Natsuki's wound had not healed and insisted on washing his back, so he delayed her while Sayu hid in the bathtub.
- Marin washed Natsuki's back and then offered to wash his clothes, while Sayu remained concealed behind the bathtub curtain.
- Natsuki got into the tub with Sayu, and Marin finished washing his clothes and went back without discovering her.
