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 . 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 (). 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.
Appearances Story Robin and Sunday are Halovians, an ancient species somewhat similar to angels that used to worship Ena, the Aeon of Order, but who changed course after Ena was assimilated by Xipe, the Aeon of Harmony. This caused the Halovians to join the Family, Penacony's ruling party, instead. Aeons are godlike entities that represent a particular school of thought. Robin's childhood took place amidst a war on the planet Epsilon, although she was born in Penacony. When a disaster struck, her mother sacrificed herself to protect Robin and Sunday, leaving them to depend on each other. Her lifelong dream was to sing and she hoped to convey her wishes for others' happiness through music. Eventually, she and Sunday moved to the planet Penacony and were adopted by its Dreammaster, or ruler. Robin's career as a singer was not without its troubles; inaccurate media reports and gossip caused Robin immense distress, leading her to contemplate giving up her role as a singer, though she would ultimately continue singing. In her spare time, she dedicated herself to giving singing lessons to children who had been displaced by war. When the protagonist Trailblazer first meets Robin after landing on Penacony, she is standing by Sunday's side but is not very talkative; she only says a few words here. After she leaves, March 7th indicates that Robin's voice is not how she remembers it and that something is off. Later, when the Trailblazer falls into the planet's Dreamscape, they feel dizzy. Robin uses her Halovian powers, which she calls "harmonizing", to rectify the dizziness.
Later, the Trailblazer tries to enter the Dreamscape again, but finds Robin's body lying in the pool needed to enter the Dreamscape. Robin's body, which has an otherworldly purple slash across it, dissipates into nothingness. Later, the player sees Sunday confront "Robin" (who was really Sparkle in disguise) about the incident and he mentions that Robin is actually only spiritually dead, not physically. He said the same thing that had just happened to Robin would happen to everyone equally across Penacony. Aventurine appears to blame Acheron for the creation of the entity that supposedly killed Robin and Firefly, and later tells Sunday that he plans to use Robin's murder to his advantage so the Interastral Peace Corporation, of which he is an executive, can take control over Penacony. However, in a private conversation with Sunday, he reveals he did not blame Acheron at all. Eventually, Sunday accuses Gallagher of the murders, but Gallagher instead alleges that Sunday has betrayed the Harmony. The Trailblazer eventually reaches the inner layers of the Dreamscape, where they are taken to meet Robin, confirming that she was not actually dead. She explains the change in her voice as a result of interference by the Path of Order against the Path of Harmony, on which her power and voice rely.
Gallagher's accusation proves true when Sunday reveals that he has been following Ena the entire time, not Xipe. He is shown putting both Robin and Welt Yang in a deep sleep. It is discovered that Sunday planned to take Robin's place as the central star of the planet's biggest festival. He explains to the group that he believed the Family had led Penacony down the wrong path and vowed to use the Path of Order to fix it. A battle ensues, but Sunday is victorious. With the help of Black Swan, the group learns that they are still trapped in a fake reality and it is revealed that Sunday used the Stellaron to merge reality and the dream to trap Penacony in a shared illusion. A Stellaron is a mysterious yet dangerous object which can cause massive changes to civilizations an ecosystems. After breaking out of the illusion, the Trailblazer, Robin and friends decide to end the crisis for good by disrupting the shared dream and having Robin use her powers to wake people up emotionally. Another battle ensues, in which the Trailblazer and friends are victorious. Robin embraces Sunday as he falls after his defeat. Sunday becomes an outlaw, joining the Trailblazer and friends on future missions.
