Creative Experience

Subsequent works include "MUSICUS!" and "BLACK SHEEP TOWN"; According to his interview, the script for "BLACK SHEEP TOWN" was completed first, and while waiting for other production stages, he wrote "MUSICUS!"
The concept behind "Hira Hira Hihiru."
In a 2024 interview, Setoguchi said that the invitation from producer Hiroki Shimada facilitated this collaboration, and the concept itself had been in the works for a long time. He originally aimed to write historical themes, but later built a game stage using fictional diseases and fantasy settings, focusing on the relationships between patients, healthcare workers, and the surrounding society.
Story and theme song
The game is set in the early Taisho era, where those resurrected by Wind Rotting Disease face challenges in their bodies, memories, and social lives. Young doctor Nisha Shoko follows Shuhei Katori in investigating, and student Takeo Tenma gradually connects with patients. Setoguchi was responsible for planning and scripting, and wrote the lyrics for the theme song "Hoshitachi no Uta," performed by KOCHO and composed and arranged by MANYO.
Opinions on the labeling of works
In an AUTOMATON interview, he disagreed with readers predicting stories with the label "Yukge" and expressed his desire to write gentle works. For "Hira Hira Hihiru," he cares about how people face their situations and treat others, rather than viewing suffering itself as the main focus.

Experience and materials on medical topics
In a 2024 interview with Hira Hira Hihiru, Setoguchi said he had worked in psychiatric facilities, interacting with patients, their families, and medical staff; I initially read related historical materials out of work and study needs. He later developed these long-standing ideas into stories about medical themes.
Choosing the meaning of branches and endings
Setoguchi stated that the choices made by MUSICUS! and Hira Hira Hihiru are intentionally meant to prompt players to reflect on their own positions; When making "BLACK SHEEP TOWN," he was reluctant to change the character through choices. The endings of the first two games are the direction of the player's chosen ideas; he does not categorize them as right or wrong based on happiness.
Why did you personally write the lyrics for 'Hoshitachi no Uta'?
In a 2024 interview, Renya Setoguchi explained that when checking the lyrics, he considers whether they fit the game's content and sometimes needs to make revisions. Therefore, when the producer of "Hira Hira Hihiru" asked who would write the lyrics, he chose to take on it personally, reducing the burden of having external lyricists repeatedly revise them.
The formation of multiple perspectives in CARNIVAL
Setoguchi recalled that the concept for "CARNIVAL" was not proposed by him; the initial outline only included Manabu Kimura's story. Since the original outline could not be changed, he incorporated the theme of child abuse into the story and incorporated the perspectives of Takeshi Kimura and Risa Kujo to organize the overall structure.
