Ars Longa, Vita Brevis

Saki Tenma

From learning piano at a young age and being in a short-term band with her childhood friends, Saki was always inclined to music. When she was hospitalized, she happened to catch a TV viewing of an idol group and she fell in love with everything about the genre. Once released and in awe of her brother's dedication to the promise he made to her, she herself was determined to become an idol in hopes of helping others the way idols helped her.

Tsukasa Tenma

Seeing his sister's love for idols and how they made her smile while hospitalized, Tsukasa made Saki a promise to become the greatest idol that would give her hope. Over the few years since, he'd taken up dance and singing lessons and applied to various agencies to better understand the world of idols, though never made it past any auditions. Upon Saki's release and learning of her wish to join him as an idol, they formed the underground duo Sunny☆Star.

Minori Hanasato

Minori became a superfan of idols when she happened to catch a TV broadcast and heard the words of encouragement that she needed at that time. From then, she delved into the world of underground idols, going by the alias Clover online and keeping up with new groups in the scene. She dreamed of becoming an idol herself, applying and failing many auditions, yet always remembered the idol's words that brought her so far and the encouragement from her online friend Amia.

Mizuki Akiyama

Obsessed with anything cute, Mizuki naturally gravitated to the world of idols. She is especially fond of underground idols and immerses herself in online circles under the name Amia. She often posts dance covers as well, though is not particularly well known. While the two have never met in person and only know each other by their online names, she is friends with Minori and encourages her to fight for her dream of being an idol, holding back on entertaining her own wish to be one too.

Virtual Singer: Miku Hatsune

Very bubbly and is always coming up with new ideas for costume and stage design. She seems a little air-headed, but is very perceptive and down-to-earth when the situation calls for it.

Virtual Singer: Len Kagamine

Always tries to act older than he seems, but caves easily to Miku's wild ideas for a while before catching himself. He's very skilled in choreography, though lacks in the fanservice department, try as he might.
