The premise remains faithful to the original but is delivered with vastly more detail and nuance.
You play as Shiki Tohno, a young man who suffered a near-fatal accident as a child that left him with two gifts: the ability to see "lines of death" on any living or inanimate object, and a set of Mystic Eyes that should have driven him insane. To cope, he uses special glasses given to him by the enigmatic Aoko Aozaki to suppress this vision.
Years later, Shiki returns to the wealthy Tohno household after the death of his estranged father. He reunites with his younger sister, Akiha, and the maid twins, Hisui and Kohaku. However, a strange condition called "anemia" causes him to black out frequently.
One night, while walking home, he encounters a woman being pursued by a monstrous entity. His eyes flare; the lines of death become visible. In a trance, he draws his knife and—without hesitation—slices the woman into seventeen pieces. The next morning, she appears at his window, alive. Her name is Arcueid Brunestud, a True Ancestor vampire, and she has a job for Shiki: help her hunt down a rogue vampire known as Roa, or be killed for "killing" her.

The remake doubles down on the horror elements of the "Mystic Eyes of Death Perception." Seeing lines of death on everything—people, buildings, the very air—is portrayed not as a cool superpower, but as a terrifying curse. The sound design and visual effects that accompany Shiki’s headaches create a palpable sense of dread. When he dons his glasses, the world becomes "normal," but the player is constantly reminded of the fragility of that peace. The premise remains faithful to the original but
This is the quintessential Tsukihime experience. It focuses on the impossible romance between a human who sees death and a vampire who cannot die. The route is significantly expanded, adding new lore about the Ancestors, deeper characterization of Arcueid (making her feel less like a typical "genki girl" and more like a tragic, ancient being), and a dramatically reworked final act. The emotional payoff is devastating.
The remake was announced in 2008 (originally as “Tsukihime Remake”) but entered development hell due to Type-Moon’s focus on the Fate franchise. After the success of Fate/Grand Order, resources were finally allocated.
The title “A piece of blue glass moon” refers to the “Moon” as both a celestial body and a metaphorical concept for the fragility of the world/unreality within Tsukihime’s cosmology. At the heart of the story is Shiki
