Janu visits Oki in the dorms, where they discuss Oki’s sister, Omina, who has been asking many questions about Janu since their previous encounter. Oki hints at her unusual nature, noting that she can anticipate Janu's intentions before he acts. Their conversation is interrupted by Eruka, who scolds Janu for his lewd choice of words and joins them in their plan to meditate.
To avoid being seen by others, Eruka provides the key to an empty, dusty dorm room for their session. Inside, Oki guides Janu and Eruka through a meditation exercise, instructing them to empty their minds and become "like water." As the meditation deepens, Janu experiences a vivid, dream-like state where he is surrounded by water and encounters a mysterious woman from his past who speaks to him in cryptic riddles about childhood memories and trauma.
When Janu eventually returns to reality, he is visibly shaken and crying, alarming Oki and Eruka. Unable to explain his intense emotional reaction, Janu abruptly leaves the room, ending the session in distress.
