Steam Store Page Opens for Novel Game COCORO About a Girl Hiding She Is a Robot

Good Smile Company and Frontwing opened the Steam store page for the novel game COCORO on June 5, 2026, with a planned release in summer 2026. The game is set in a world where robots run rampant and follows the first love between a boy and a girl who hides that she is a robot. The scenario is written by Asta Konno, known for ATRI -My Dear Moments-, with character design by Akio Watanabe. Hina Youmiya voices the protagonist Kokoro. Newly announced cast members include Hikaru Tono as Kazane Ryuzaki, Yasuaki Takumi as Daichi Amai, Riona Imaizumi as Kosame Amai, Maaya Uchida as Kirika Hatsuki, and Shuta Morishima as Kotaro Murakumo. The opening movie has also been released. A collaboration illustration between COCORO and ATRI, drawn by Akio Watanabe and Yusano, has been revealed and will be displayed at the Good Smile Company Game Exhibition, with acrylic stands sold as merchandise for 3,000 yen. A follow-and-repost campaign for an autographed shikishi board by Hina Youmiya runs until June 19. The game supports Japanese, English, and Chinese languages on Steam and other digital download sites.

Hina Youmiya, who voices Kokoro, said in a comment that as AI technology evolves, she thinks about what it means for her as a human to perform, and that she faces Kokoro-chan every day. She said that as the story progresses, her own heart is shaken a lot, but what Kokoro experiences is completely different, so she is collecting many things not in her repertoire and recording carefully with the creators.

Hikaru Tono, voicing Kazane Ryuzaki, described her character as Hinata's childhood friend and a big-sisterly girl who cares about what she wants to protect. Tono said she thought "What a dazzling girl!" while reading the script, but noted that Kazane also uses many unladylike expressions. Yasuaki Takumi, voicing Daichi Amai, said he was drawn into the attractive world and read on with excitement and anticipation. Riona Imaizumi, voicing Kosame Amai, said her first impression of the character was "Super cute!" and that she related to her bossy-at-home side. Maaya Uchida, voicing Kirika Hatsuki, said that through various relationships she felt from reading the script that connections between people are an accumulation of miraculous things, like the difficulty of understanding each other's hearts. Shuta Morishima, voicing Kotaro Murakumo, said that in today's world where AI is evolving daily, he felt as if he were peeking into the world at the end of that evolution.

The opening theme "Signal" is performed by Runa Mizutani of NanosizeMir, with composition and arrangement by Fuminori Matsumoto and lyrics by Yuichi Kuwashima. SD art is by Mai Nanaka, backgrounds by Waishu, and music by Fuminori Matsumoto. Production is by Frontwing. Hina Youmiya will appear on "Good Smile Fes 2026: Good Smile New Game Special Feature Corner" airing from 10:00 PM on June 5.
