Robin (Chinese: 知更鸟; pinyin: Zhīgēngniǎo; lit. 'mockingbird') is a character from the video game Honkai: Star Rail, developed by miHoYo. In the game, she is a singer from the fictional planet of Penacony. She is a Halovian, an angel-like species with wings on their heads and a halo-like accessory. She was released in version 2.2 of the game on May 8, 2024. On June 30, 2026, it was announced that an additional version of Robin would be released later in the year, called Robin • Summeretto (知更鸟·晴歌; Zhīgēngniǎo: Qínggē; 'Mockingbird: Sunny Song'). Robin was received warmly by players and critics, who applauded her for her cute appearance and inspiring message. There was a large amount of speculation as to whether or not Robin was alive after she was believed to be a murder victim. miHoYo also produced an EP for her, titled INSIDE, which topped more than ten music charts. miHoYo launched a project to use Robin's music to raise awareness for hearing loss in December 2024.
Design and voice acting Information about Robin was first released on March 12, 2024, when she was described as a renowned singer from the fictional planet of Penacony. Her appearance was also revealed on this day. Information about her gameplay was released on April 30. On May 3, miHoYo released her character introduction as well as a trailer called "If We Had Wings" detailing the backstories of Robin and her brother, Sunday. In the trailer, younger versions of the two are seen as Robin reassures a group of children while telling them a story. miHoYo released her combat trailer on May 7, called "Sway to My Beat", which pictured Robin walking through the streets of Penacony and introduced one of Robin's fictional songs. She first appeared in version 2.0 of the game as a non-player character, and was released as a playable character in version 2.2 of the game on May 8. Robin's speaking voice is provided in English by Alice Himora, in Chinese by Qian Chen, in Japanese by Kaori Nazuka and in Korean by Shin Onyu. Her singing voice was provided by Chevy in all languages. Nazuka said in an interview that although Robin was beloved by her people, she was not content with that and wanted as many people as possible to feel happiness through her songs. She added that she was careful not to change the way Robin's attitude sounded when interacting with one character compared to the next, aiming to keep her behavior consistent except for when Robin was talking with Sunday. Nazuka added that Robin was very strong, but that she would not impose that strength on others. Because of this, she made sure to use words that came across as well-refined and gentle. Regarding the relationship between her and Sunday, Nazuka thinks there is a fundamental difference between Robin and Sunday's understanding of freedom and protection. This was already reflected in their childhood discussion about the happiness of caged birds: Sunday believed that being loved in a safe environment was happiness, while Robin believed that birds should find happiness in free flight, even if they face the unknown. Despite the difference in their views, Robin still deeply loves her brother and she especially cherishes the childhood memory of singing on a cardboard box with Sunday. Nazuka thinks that deep in Robin's heart lies a contradiction in that she sings both for her fans and for her brother and that this complex emotion has become an invisible shackle binding her. In an interview with Famitsu, the development team stated that Sunday pursues a sort of happiness like an eternally shining lone star, while Robin rejects this and believes that the sky should be filled with countless stars and that Sunday does not have to bear his burden alone.
Music miHoYo also released an extended play (EP) of Robin's songs on May 9, 2024, called INSIDE (空气蛹; Kōngqì yǒng; 'air chrysalis'). The extended play initially featured three songs, all sung by Chevy as Robin. On June 22, the fourth song, "Had I Not Seen The Sun", was also released. INSIDE topped more than ten music charts. An official documentary revealed that the game's composers sought inspiration from their imagination to create the music.
In an interview with Famitsu, the development team discussed the creative concept behind the songs. Regarding "Hope Is the Thing With Feathers", the team explained that the song is intended to faithfully portray Robin's life journey. The song portrays her as a bird protected within a cage, lost and uncertain. However, she later broke free from her restraints and flew out from her comfortable nest, becoming a renowned singer. At the end of the Penacony storyline, after defeating Sunday alongside her friends, she resolves to take her brother's place in protecting Penacony, using the power of Harmony to spread her song to all things in the world. As for "Sway to My Beat in Cosmos", the team described it as an emotional and narrative continuation of "Hope Is the Thing With Feathers"; if the latter represents Robin breaking free from her shackles and exploring freedom, then the former depicts her having already embraced that freedom and bravely stepping onto an unknown journey.
