evokes the image of a "silky haired beauty." Supporting characters Saya Minatsuki was an accomplished sweeper and close friend of Train. Her involvement with him led to his more human outlook on life and his departure from Chronos. Train denies having had romantic feelings for the 19-year-old, stating he "fell in love... with her way of living. Not bound by anyone or anything... like a stray cat." Saya has no memories of her life before the age of ten, due to heavy abuse from her parents. Her first real memory is waking up in hospital and being carried off to a relative's house. She constantly wears a yukata because she likes their appearance and thinks it makes her stand out. She develops the over the course of five years, allowing her to fire bullets that ricochet off hard surfaces and strike opponents at odd angles and different velocities. Creed, seeing that Train's personality is changing due to her, confronts Saya and the two fight until she is stabbed while being distracted by kids. She does manage to destroy his sword before dying. Devastated by her death, Train struggles while whether or not to get revenge on Creed, until settling on taking him in as a Sweeper instead of killing him. Saya's spirit later helps Train defeat the Doctor's Warp World and aim his final shot at Creed. Saya's name just popped into Yabuki's head while he was looking at her face. Tearju Lunatique is one of the top authorities in nanotechnology and leader of the group that created Eve. Eve's DNA was taken from hers, thus making them look identical. She is very bad at household chores and has the ability to trip over nothing. Train, Sven and Eve seek her out after Train is shot with the Lucifer bullet and turned into a child, in hopes she knows how to revert it. Because of the huge cost of a vaccine, she informs him the only other possibility is to mentally concentrate and visualize changing his body, similar to how Eve does it. The Apostles seek her out at the same time so Creed can obtain immortality, but she refuses, having resolved to never experiment with humans again. In the anime, Tearju is absent from this part joining much later after the assault on the Apostles, because she had brain damage from an explosion at the time of Eve's creation.
