The Thousand-Year Blood War arc
On the day he is scheduled to take over guarding Karakura Town from Zennosuke Kurumadani, a sleep deprived Ryūnosuke arrives late and is told off by Zennosuke. Ryūnosuke explains that he did not sleep due to being nervous about his new assignment. Shino greets Ryūnosuke and tells him to prepare for their mission. He tells her that he is scared about the high rate of Hollows in Karakura Town. Shino scolds him over this attitude. She asks why he doesn't proudly stick out his chest. He is hit for making a comment about how she is flat chested. That evening, Ryūnosuke and Shino are brought to the Human World by Zennosuke, who leaves them after offering them some encouragement. Shino tells a reluctant Ryūnosuke to split up.

Ryūnosuke quickly finds a Hollow and runs from it, calling for Shino. However, when he finds her, she is being held by a large Hollow. Ryūnosuke draws his sword and decides to save her, but he is attacked and left lying on the ground badly injured. He is saved by Ichigo Kurosaki, who defeats the Hollow and introduces himself.

Ryūnosuke wakes up in Ichigo's room and is told he can leave. Orihime arrives, happy that he has woken up. He sits confused as Ichigo and his friends bicker. After some time he screams, noticing that Ichigo is the person he met yesterday. Ichigo comments that he is slow and corrects him saying that he has been asleep for a day. He then remembers Ichigo and the others defeating the Hollows. He is shocked that they were able to defeat the Hollows so quickly despite how strong he heard Ichigo was. Ichigo hands him some bread and tells him to get in his Gigai. Ryūnosuke comments that he shouldn't do that when Shino arrives. He is happy to see her and the two bicker with each other. The pair then look on as Ivan Azgiaro appears in the room and is promptly kicked out a window by Ichigo, wondering who he was.

Ryūnosuke's Zanpakutō resembles a regular katana with a rectangular tsuba.
