About this gameFull description from Steam
About BLUE REFLECTION The BLUE REFLECTION series began with the release of the first game in 2017, which told the story of an injured former ballerina as she used her powers as a magical Reflector to form bonds with others and fight off the looming threat to the world. From there, this RPG series expanded into an anime and a mobile game release, as well as a sequel console release. BLUE REFLECTION Quartet contains all four of these emotional stories in a single collection. New features make the series more accessible than ever before, including a reference which both explains the setting for new players and provides a deeper look into the world for returning fans. The games within this collection can be played in any order. BLUE REFLECTION A console game which told the story of an injured former ballerina as she used her powers as a magical Reflector to form bonds with others and fight off the looming threat to the world. Experience academy life and a fantasy world carefully crafted by famed illustrator Mel Kishida and writers Keiichi Shigusawa, Yusaku Igarashi, and Koji Natsumi. Graphics and usability have been improved compared to the initial release in March of 2017. Character models and environmental textures have been updated to high resolution versions, and new visual effects such as glistening water add to the world's atmosphere. Furthermore, new features such as increased movement speed while exploring and autosave have been included, offering a more enjoyable experience than ever before. BLUE REFLECTION: RAY An anime that tells the story of magical Reflectors clashing with each other over their conflicting beliefs and emotions. Based on the world of the original BLUE REFLECTION game, this anime was the first additional entry in the BLUE REFLECTION mixed media project, airing from April to September 2021. BLUE REFLECTION Quartet tells a condensed version of the story, with the major characters rendered in 3D. Follow Hiori and Ruka as they explore the world of the collective human unconsciousness, known as the Common, while re-experiencing their memories on their way to confront Shino. The anime's story will be told as they collect their scattered memory shards, and a new prologue and epilogue will connect this entry to the other works in the series. BLUE REFLECTION: SUN A mobile game that told the story of a team of girls living in a dying world as they hold on to hope for the future. Based on the world of the original BLUE REFLECTION game, this game first released in February of 2023 as part of the BLUE REFLECTION project. SUN's story has been remade as a console game in BLUE REFLECTION Quartet, using the systems of BLUE REFLECTION: Second Light to recreate the memorable battles of the original game. This game tells the story of SUN across 24 events featuring new character interactions. The prologue and epilogue from the original release also connect this entry to the other works in the series. BLUE REFLECTION: Second Light A console game that tells the story of a group of girls with no memories who find themselves in a strange world. Through their adventures, the girls must look deep inside their hearts, regain their memories, and discover the truth about the world they are living in. This entry in the BLUE REFLECTION project first came out in October of 2021. This release for BLUE REFLECTION Quartet features eight additional characters from RAY and SUN who can join you in battle. These new characters also join Yuzuki and Lime as new additions to the Photo Mode! New features such as increased battle speed, faster movement speed while exploring, and event fast-forwarding have been included, offering a more enjoyable experience than ever before. Reference A database that gives deeper understanding of the world of the BLUE REFLECTION series. Here you can check chronological flowcharts of major events in the stories, as well as character relationship charts across the entire series. This in-depth overview of the characters and the series's setting will make the games even more enjoyable! There is also a gallery where official artwork created by Mel Kishida can be viewed. The Stories of Each Game BLUE REFLECTION After a leg injury puts an end to her dreams of becoming a ballerina, Hinako meets Yuzuki and Lime, who grant her strange, magical powers. Hinako is told that if she defeats all of the Sephira currently threatening their world, a wish of hers will come true. Desperate to return to the stage, she sets her sights on gathering shards of emotion known as Fragments in order to grow strong enough to destroy the Sephira. BLUE REFLECTION: RAY Hiori Hirahara is positive and upbeat, and always happy to lend a helping hand. Ruka Hanari is shy, awkward, and can never seem to find the right words. Together, they'll change one another...and the world. BLUE REFLECTION: SUN Play as the leader of the "weakest squad in history" in a world on the brink of destruction. Fight the Ash-born Testa, resolve your squadmates' issues, and hold the line against the spreading corruption. BLUE REFLECTION: Second Light While on her way to summer school, Ao suddenly finds herself in a school surrounded by water. Ao isn't the only one at the school, but the other girls living there have all lost their memories, not even realizing anything was strange until Ao's sudden appearance. Hoping to find out more about this strange world, Ao and the others band together to explore the otherworldly Heartscape that has shown up beside the school.
