While Rantarou and his classmates are relaxing by the riverbank, Heisuke unexpectedly emerges from the water. He explains that he utilized the Suiton no Jutsu technique to conceal his presence from Kan'emon. Fearing discovery, the group agrees to keep his location a secret. Rantarou and his friends promise Heisuke that they will not inform Kan'emon of his whereabouts. This agreement allows Heisuke to remain hidden from his pursuer while the students continue their time near the river without interference or further complications regarding his stealthy arrival.
