Yuki Makimura was a Slayer.
No information is known about Yuki; all the following information comes from noncanon sources. Though presumably her siring remains canon, this is unconfirmed.
Calling and Siring
Yuki Makimura was called as a Slayer in Japan during the 18th century. She was trained by a samurai Watcher. Yuki's Watcher failed in his duty, and, in penance, commited Seppuku. Three months after his death, Yuki went up against the Master, who killed and sired her. While most Slayers welcome death, Yuki didn't want to die. Upon becoming a vampire, Yuki gave her complete loyalty to the Master and served him willingly from Japan. The Watchers Council removed Yuki from their records, but failed to cover up the two missing years in the Slayer timeline.

In Sunnydale circa 2000, Dawn Summers discovered Yuki's missing time slot in the Slayer records, and Spike told the Scooby Gang of the disgraced Slayer-turned-vampire. Yuki came to Sunnydale with the Eidu, a sect of blind vampires, to resurrect her sire. She planned to take revenge on Spike for killing the Anointed One and to use Xander Harris as a vessel for resurrecting the Master. Dawn stopped the Master's resurrection and Yuki was staked by Dawn's sister and Slayer, Buffy Summers.
Behind the Scenes
- Yuki originally appeared in the False Memories storyline in the Buffy the Vampire Slayer comic book. Although this story is non-canon, Yuki herself was elevated into a canonical character thanks to a cameo appearance in Tales of the Slayers.
- Like Yuki, Simone Doffler would be sired into a "Slaypire".
