INS-mode is a doujin circle led by Amanagi Seiji (天凪青磁). Active since the print era, it distributed Lovely angels!, an Angel Beats! derivative, at Comic Market 82 in the summer of 2012. Commercially, Amanagi Seiji has published collections including Mannaka♥Namaiki and Yuri-iro no Hibi (both 2017) with Fujimi Shuppan. The circle's FANZA releases began in 2017 with Risō no Imōto, an incest series about a brother and sister that ran to a seventh installment and a compilation. Chikan no Sonzai Shinai Subarashii Sekai, begun at Comic Market 94 in summer 2018, takes groping (chikan) and hypnosis-brainwashing as its subjects in settings such as commuter trains; moving from the classroom to the library, a café and the seaside, it has continued into 2026 and gathered two compilations. Since 2025 the circle has been adding installments of Isekai Seikan Therapist, built on the premise of reincarnation in another world. Its works have appeared on DLsite since 2019.
