Cerulean Days

Cerulean Days is a visual novel set on Inre Island, a seemingly idyllic, modern island in the Atlantic Ocean. The story follows two social outliers, mellow Michael and competent Séverine, as they uncover the effects of a biological attack and the changes that followed. As they deal with loss, they form bonds, find solace, develop feelings and investigate the island’s mysteries and apparent conspiracies.

Inre Island

In 2016, Inre is prosperous and peaceful, with a mild climate and a society that values harmony. Though it is a sought-after destination, travel there is limited by its high cost and a strict entry regime requiring a special visa.

Over six months in 2018, a lethal biological attack claims many lives. The government puts a controlling plan into effect to prevent future attacks. In the years that follow, the island’s citizens face changes to their way of life. On a dark, damp day, the internet is shut down, cutting Inre off from the outside world.

In 2020, after a long spring without internet, a replacement system is introduced. The new system and its digital setbacks transform daily life, leaving many unable to adapt and spiritually stuck in the world they have lost. Some want to escape, while others want to reset and forget. People who would never have met come together, and an island once unfamiliar with sadness experiences it firsthand.

The characters

The story centers on Michael and Séverine, alongside people whose lives have been shaped by Inre’s upheaval:

• Séverine: A creative, intelligent professional pastry chef at a luxurious mall. Strict schooling and a difficult upbringing have led her to set high standards for herself and others. She has a bold side that she usually shows only around people she trusts. After finding comfort in online conversations with like-minded people, she now has to face a social landscape changed by the island’s new circumstances.
• Grace: A kind, bubbly woman who works at Inre City High School and was Michael’s homeroom teacher for three years. After a personal tragedy in Michael’s life, she supports him, and they come to live together as an uncommon family, finding comfort in each other’s company.
• Rose: A cheerful full-time streamer whose online community was central to her life. In a society without internet, she feels lost and struggles to adapt, with her stubbornness making it harder for her to let go of the past.
