Tsuki is a supporting character in Prologus: Bionic Fantasy.
Tsuki is a beautiful woman in her mid twenties, with black hair and blue eyes.
Tsuki is quite spiritual, and feels very connected to the entirety of Ankoku Nui, hearing it's "cries" from time to time. She feels quite depressed and heartbroken that the other denizens dismiss her talk of hearing the planet's cries for help as delusional fairy tales, but she starts to feel a little better with the knowledge that at least Crono and Zonan, who are passionate about preserving life, can relate to her.
One of the last remaining Cetra, from the time before/during the Shinra Company's establishment on Gaia, went with those who were chosen by the Choujintei to inhabit Ankoku Nui, where Tsuki would be born. Growing up in Ga-Ao, Tsuki lost her boyfriend to the mysterious unidentified plague that has similarly claimed other lives at random, so in their need to console each other, she and her friend Yuria entered into an intimate relationship with one another.
Growing up in Ga-Ao, Yuria lost her boyfriend to the mysterious unidentified plague that has similarly claimed other lives at random, so in their need to console each other, she and her friend Tsuki entered into an intimate relationship with one another.
During Crono and his group's time in Ga-Ao, Yuria and Tsuki invited Zonan to swim with them, and explained to Zonan a bit more about love. Sometime after the trio makes for Ta-Aka, Hairo breaks into Tsuki and Yuria's' home, despite Starlighter's attempts to stop him, and threatens to rape Yuria with Tsuki being forced to watch for as long as either refuses to give him Crono's location. Tsuki pulls Hairo off of Yuria, ripping most of his uniform off in the process, but he impales her from the back of her stomach. Horrified by this act, Yuria grabs a katana and impales Hairo through the heart, only to learn that his heart is in the right side of his chest, and most of his organs have been replaced with machinery. Hairo prepares to kill her in retaliation for discovering this secret, but Starlighter finally gives him Crono's location, and Hairo storms out of the house to pursue the Matoran, leaving Yuria and Tsuki in anguish over their physical and psychological wounds.
Creation and Development
"Tsuki" means "moon" in japanese. She was given this name in contrast to, and for the same symbolic reason as her descendant Aerith, whose name sounds like Earth.
- Despite them both being stabbed from behind by a major antagonist, Tsuki ironically survives what Aerith did not.
