- "You're hot, you have great taste, you're a hell of a Slayer, and you smell good."
- ―Buffy Summers to Satsu[src]
Satsu was one of the new Slayers activated by Willow Rosenberg in 2003. She was recruited into the Slayer organization, where she trained under Buffy Summers. Satsu formed a friendship and later a sexual relationship with her mentor, before eventually becoming the leader of her own Slayer squad in Tokyo.
Early Life and Calling
- "It's a furisode! Girls wear them when they come of age to show they're single and available for marriage. My parents bought it for me before I destroyed them with my gayness."
- ―Satsu (while possessed by a Vampy Cat)[src]
Satsu was born to traditional Japanese parents who wished to see their daughter marry and have children, only to be devastated when she came out as a lesbian. Satsu was activated as a Slayer while in school and the rush of power knocked her off her feet. Eventually, she was recruited into the Slayer Organization where she was placed in Buffy Summers' squad in Scotland. Satsu proved to be an exceptional and skillful warrior, quickly earning the respect of her mentor, and in turn, she began to have romantic feelings about the older Slayer. When Buffy was put in a mystical sleep by Amy Madison that only a kiss of true love could break, it was Satsu who secretly awakened her, proving that her feelings were far more than just a crush. Shortly afterward, Buffy chose Satsu to come with her to rescue her friend Willow Rosenberg from Amy, battling their way through a U.S. military base with ease. The fact that Satsu was chosen for the mission out of all the Slayers prompted some friendly envy from her peers Leah and Rowena, who told her not to embarrass them. Satsu was also amongst the troop of Slayers who travelled underground to take down Yamanh of Hoht.
Relationship with Buffy
Some time after their mission to rescue Willow, Buffy once again chose Satsu to help her clean out a nest of vampires. Buffy admitted that she knew it was Satsu who kissed her, partially from recognising the taste of her cinnamon lip gloss. She explained that she was deeply flattered to know she felt that way, but was not gay herself. Buffy also warned that people who love her have a history of getting hurt; this prediction quickly proved true when Satsu was suddenly knocked out by Twilight. When she regained consciousness, Buffy comforted her in hospital. One thing led to another, and the two Slayers ended up having sex, only to be discovered by Buffy's shocked friends, who each walked in on them in bed together. When Satsu commented on Buffy's plan to take all of the Slayers located in Scotland to retrieve the stolen Scythe, Buffy told her to follow orders, leaving Satsu obviously hurt. This prompted Willow to have a heart to heart with the Slayer, in which she explained that Buffy was different from them due to her responsibilities as leader.
- "You said I'm your best fighter... you know I'm your best fighter... So you're either leaving me behind to avoid me or protect me. [...] I don't know if I should be hurt or touched, but either way... I'm not following your orders. Not this time. I'll see you on the battlefield. Ma'am."
- ―Satsu asserts herself to Buffy.[src]
In Japan, Buffy tried to order Satsu to stay behind and offer help to the local Slayers, who had just lost their leader Aiko to a brutal vampire attack. Satsu refused and insisted on taking part in the fight. She participated with Buffy's group during the attack on the vampire's headquarters, taking back the stolen Scythe and plummeting off the side of the building, being caught by Willow moments before landing on the sidewalk. Satsu later commanded the rest of the Slayers into attacking the rest of the Japanese vampires, who had lost their mystical powers.  Back at the Japanese Slayer base, Buffy and Satsu talked about their night together, and Satsu's belief she needed to stay away from Buffy, taking the position of leader in the Japan. When Buffy asked if this was goodbye, Satsu offered to leave the goodbye until the next morning, leading them to spend another night together.
Tokyo Squad Leader
Satsu proved competent in her leadership role. Her squad successfully commandeered a Korean submarine which had been hijacked by vampires. She neglected to report this detail, instead letting her Slayers use the sub to their advantage. Eventually, Kennedy was assigned to evaluate Satsu's position, partially due to her vagueness in the Korean report. Kennedy meanwhile, had a personal agenda, wanting to advise Satsu after her relationship with Buffy. She explained that Satsu was "not the only fool to ever wrinkle the sheets with a straight girl", and advised her to move on from Buffy. While investigating the Santorio Corporation, Satsu was possessed by a demonic Vampy Cat, which she later nicknamed Fluffy. Kennedy excorcised Fluffy from Satsu's body, and the Tokyo Slayer squad discovered that Santorio Corp were shipping their Vampy Cat inventory to Scotland to attack Buffy. Kennedy and Satsu intervened, and battled the collective Vampy Cats called "the Swell", who revealed their affiliation with Twilight. The Swell was defeated by a missile launched by the Slayers' submarine, and an impressed Kennedy informed Satsu that she would receive a positive evaluation. Afterward, Buffy told Satsu that, in light of vampire Harmony Kendall's reality show making Slayers unpopular with the public, the Slayer army would have to change who they were. Satsu agreed, and disposed of the cinnamon lip gloss she had kissed Buffy with.

Powers and Abilities
- "You're my best fighter, Satsu. You could lead the crew some day."
Satsu had the normal powers of a Slayer, including superhuman strength, reflexes, agility, accelerating healing, and prophetic dreams. Her weapon of choice seemed to be a katana. In terms of combat skills, however, she might be far superior to other Slayers, as Buffy herself had frequently commented how impressive her fighting skills were.
- Satsu: "Don't make fun of me. This isn't some crush..."
- Buffy: "Your kiss couldn't have woken me up if it was."
- — Buffy acknowledges the depth of Satsu's feelings.[src]
- Buffy Summers — Satsu was Buffy's favourite of her squad, and she often chose her for special missions. Satsu was deeply in love with Buffy, but her romantic feelings were not reciprocated. However, Buffy held Satsu in high regard for both her Slayer abilities and her fashion sense, and the pair's close friendship eventually became sexual. When Satsu asked Buffy what had happened between them and how to deal with it, Buffy claimed that she had a "wonderful night" but that things wouldn't go any further. It was Satsu who ultimately ended their relationship, requesting to remain behind in Tokyo because she could not move on with Buffy right in front of her, and the pair shared a final night together as goodbye. Satsu eventually resolved to get over her feelings for Buffy after some advice from Kennedy.However, soon after, upon that discovery that Buffy was having sex with her ex-boyfriend Angel, Satsu appeared hurt or disgusted, and gave the scanner to Dawn and left the room.
- Rowena and Leah — Satsu appeared to share camaraderie with the other Slayers in Buffy's squad, despite their teasing her for being Buffy's favourite.
- Willow Rosenberg — Willow became protective over Satsu after discovering her one-night stand with Buffy. She gently explained to her that Buffy was not like the two of them, but rather "the general", and that she was not "a friend of Sappho". She also cheered Satsu up by humorously inquiring what Buffy was "like in the sack". Later, Willow warned Buffy to be careful with Satsu, stating, "I gotta look after my sisters here".
- Kennedy — Kennedy volunteered for Satsu's performance evaluation, wanting to counsel her through her recent short-lived relationship with Buffy. Initially, Satsu was defensive over being lectured by "the other lesbian Slayer", and rejected her advice. However, the pair bonded while battling the Swell together and eventually formed a friendship, with Satsu inviting Kennedy to come shopping with her.
