Danshi Kinsei Game Sekai de Ore ga Yarubeki Yuiitsu no Koto: Yuri no Aida ni Hasamaru Otoko toshite Tensei shiteshimaimashita (男子禁制ゲーム世界で俺がやるべき唯一のこと 百合の間に挟まる男として転生してしまいました, The Only Thing I Must Do in an All-Girls Game World: I Got Reincarnated as the Guy Stuck Between Yuri Couples) is a 2023 Harem romantic comedy light novel series written by Hazakura Ryou and illustrated by Haishiki.
A yuributa gets killed by a Truck after jumping in to save a pair of women who would have died otherwise because he believed they were actual lovers. He is reincarnated into his favorite game, the Yuri JRPG Everything for the Score (Esco). Before he can celebrate, he realizes he is now Sanjou Hiiro, reviled as "the guy who gets in the way of yuri" and a character with more death flags than a flag store. As he strives to avoid his own death and continue his yuributa ways, he begins to change this world which explicitly rejects men.
The series was first published on the novel posting website Shousetsuka ni Narou in October 2021. It was later acquired by Media Factory, who began to publish the series on April 25, 2023. A manga adaptation illustrated by Kusono Kameyo began serialization in Dengeki Daioh on December 24, 2024. The English localization of the light novel became publication under the Yen Press imprint under the title The Only Thing I'd Do in a No-Boys-Allowed Gaming World on February 18, 2025.
