The brothers and sisters of Gesheng
Riku is a second-year student at Hekisen Academy and aims to marry Towako. His younger sister, Gesheng Maoyi, is a first-year student at the same school, one year younger than her brother, and has excellent academic and life arrangements, familiar with his laid-back side. She is a member of the swimming club, finishing second in the prefecture in the women's 50m freestyle and enjoys collecting 500 yen coins.
The Hayasaka sisters
Ui admires Towako Hayasaka and is close friends with Towako's younger sister, Onan Hayasaka. The developers clearly made Uyoi the main female lead, with Towako and Tanu as secondary characters. The 2025 public trial is depicted from Oshima-sensei's perspective, teasing Riku and Towako's relationship, but Towako, as the teacher, stops his interference.
Mao Yi and Narration Design
The 2026 development draft further emphasizes that Mao is not good at socializing, and aside from her older brother, she finds it difficult to speak naturally to men. The author plans to supplement the story from the side stories of the main characters and passersby from different perspectives, and arrange illustrations and corresponding dialogue materials for dubbing references. There are also plans to change the title screen as you read the story, using new CG to represent the story stage.
Development record
The project was announced on April 1, 2025, with the official website containing April Fools' Day wording. In December 2025, the official release of the Oru Go-Uru notes is still undecided: protagonist voice lines are planned to be added, but a reading mode that only retains dialogue and hides inner thoughts will be postponed. On August 31, 2026, he clearly stated that the project had not been canceled, that recent news had decreased due to the postponement of Clover Memory's, and continued to introduce the script, characters, and background production. There is no official release date or complete version announcement yet.
