### Sailor Starlight

Sailor Star Fighter is the middle-heighted of the Sailor Starlights. She has long black hair tied into a long ponytail, identical to the other Starlights. She has blue eyes. Her sailor uniform, identical to the other Starlights, is a navy blue two-piece outfit, consisting of a bikini-like top and hotpants. She wore knee-length boots and elbow-length gloves. She wore a golden beaded tiara, beaded belts on her waist, and golden star earrings. Her secondary color was light blue. She also wore a light blue belt-like choker and belt-like straps on her upper arm.

## Personality

Seiya's personality was considerably lighter than that of the other two Starlights. She was much more childlike in her attitude, with a slight prankster edge to her character, and there were brief moments when she was not thinking about her mission. She had a cheerful disposition and was much more easygoing. She was also more willing to become close to Usagi and her friends, while the other two Starlights mainly kept to themselves and originally refused to work with the Solar System Senshi at all. As mentioned by Taiki and Yaten, Seiya is also a sore loser.

## Information

Seiya is a Senshi from another star system who came to Earth looking for their princess who had fled here. She also developed quite the crush on Usagi and even kissed her on the check when they returned home. She was suddenly summoned back to earth after Usagi shattered her crystal to escape the nanobots control. Grabbing her out of the air she could only stare at the other Senshi in confusion, not understanding what was going on. She came to her senses upon noticing how lifeless Usagi was this prompted the others to remember that they needed to escape. Mercury checked up on Usagi and determined that she was alive, though she needed a more proper examine. Tuxedo Kamen took Usagi from Seiya as they made their way outside, deciding they’d figure out what to tell everyone when the time came.

Uranus however broke off to go and find Kasumi, and much to her confusion none of the others moved to stop her. The group teleported out and Mamoru de-transformed and rushed off to find a doctor. After a moment of consideration, Seiya stayed behind and looked to the others. They decided that it would be best to stay as it would make it easier for him to explain things. At this point Luna made her presence known and demanded that they explain what was going on, something Seiya agreed with.

Seiya contacted Princess Kakyuu who advised her to stay on earth since they didn’t how she got there, so, going back may be pointless anyway. Could find myself right back here again. She was informing Mamoru of this when Usagi woke up. Not sure what was going she attempted to pretend she still asleep only for Mamoru noticed her stirring and came over to check up on her. With the jig up she opened her eyes and asked if this was real. Mamoru explained to the confused Seiya about how she had been controlled with special nanites that trapped her mind in an illusion.

Mamoru assured her that she was awake, but the just led to the question of how she was still alive. She looked to Mamoru and Seiya for an answer, but since they didn’t have an answer Seiya decided to change the subject to the mystery of how she was teleported to Earth. She even joked about how she would of arrived naked if it was just a few minutes later. Usagi noticed she was female, and Seiya explained that her male body was no longer needed after she went home.

Seiya decided to inform the others that she was okay, leaving Mamoru to explain to Usagi as much as she could about what had happened. she found them licking their wounds in in the hospital cafeteria. While they were relieved that Usagi was okay this just brought about further questions, such as why didn’t she fade away like all the other Senshi who had their stars removed. Not to mention how she summoned Seiya. Setsuna found this amusing as the answer was obvious to her.

They were under the assumption that it was Usagi's kidnappers that caused time to shift, neither Rose or Kasumi had that level of power only Usagi herself. Minako was the first to voice what everyone was thinking and asked what they do next. That Setsuna couldn’t answer as knowing Usagi was the cause of everything didn’t mean she knew how or why she was able to do it. They needed more info and to get they needed to go to the Moon Kingdom. It turns out that while everything above ground is in ruins, the complex below the ground is still fairly intact. If Ami could get the city's central computer running again they could get the answers they needed.

That still left the question of how they were going to get there which Rei was quick to point out. Setsuna informed them that the Moon Kingdom had several special transit points set up as gateways between Earth and the Moon. They also wouldn’t need any space suits. Needing only a small group to go it was suggested that it consist of Haruka, Ami, Setsuna, Usagi, and Mamoru. With that came the problem of Kasumi having seen Haruka who after a moment volunteered to talk to her.

Being back on earth was hard for Seiya, part of her wanted to be with Usagi, but the other part of her knew that it would be totally inappropriate. Something Princess Kakyuu could see when she finally reported in after the group left for the teleportation point. She offered to have someone take her place, but Seiya declined. They still didn’t know if she could leave and even if she could it would take a week or so to get here from there.

Kakyuu was worried, Sailor Moon had always shown to have a considerable amount of power, and despite Seiya being adamant that she didn’t show any signs of what happened to Galaxia. It nonetheless remained worrisome that something has happened to her. Seiya promised to contact Kakyuu the moment she knew something, but as of know they were just going to have to wait. Before ending the transmission Kakyuu advised Seiya not to persist in avoiding her feelings. They may not be returned, but that does not make them go away.

Sadly decided not to heed Princess Kakyuu’s words and kept her distance until it was determined that it was safe for her to return home. She went to dorm to inform Usagi of this. After some awkward conversation Usagi apologized for not saying anything when Seiya left the first time. Given that she didn’t know if Mamoru had been killed by Sailor Galaxia Seiya never really expected an answer, so was amused that Usagi felt she needed to give one.

When the reason for her visit finally came she told Usagi that it wouldn’t be for about a week, so this wasn’t goodbye and she promised not to leave before coming back. Seiya made a joke about still not knowing if she could leave only to see how the reminder that she had no control over her abilities depressed Usagi. Knowing nothing would soften the blow she decided to leave. Words failing her all Usagi could do was smile as she led Seiya to the door.

The day of Seiya’s departure she was in the process of cleaning up and taking care of some final tasks when she was interrupted by Eris. Getting the same feeling she got from Galaxia Seiya tried to collect her nerves at being confronted by this naked opponent. Seiya was once more stunned when Eris revealed she knew who she was, but before she could do anything Eris plunged her hand into her chest and took out her star seed. Luckily she quickly put it back and introduced herself.

As Seiya was coming to terms with what was happening, Eris called her a coward for never being willing to follow her heart. In an effort convince her to admit her love to Usagi she told her to look into the history senshi relationships. Before she left she also told her to ask Usagi about the dream she had.

This put Seiya in a conundrum Eris was essentially considered the god of mischief on Kinmoku. So did she heed her warning and stay on earth or did she go home. Not helping matters that it seemed that senshi were truly soul mates whose love continued even through death and rebirth. Meaning that it was possible she would never get over her feelings for Usagi. So to get her feelings in order she asked Usagi to meet her in the park.

She asked her specifically why she was there and if had to do with a dream she had. Seiya had a brief moment of triumph before noticing Usagi troubled demeanor and regretting bringing the subject up. However, before she could say anything more on the matter, Usagi told her about the vision while under the effects on the nanomachines. This caused the weight of everything to finally come down on Usagi. Now that the future was no longer certain she didn’t know what to do.

As Seiya tried to figure out what to do now that she opened this can of worms. Usagi was kidnapped by by two ascended senshi. A third one then appeared and told her not to interfere as she was paralyzed with fear.

Seiya was taken to some sort of auditorium and for several days attempted to free herself, to no avail. Usagi was placed in some sort of suspended animation, but Seiya’s attempt to free her ended equally in failure. The only other person with them was their capture, which Seiya was able to realize, because despite being in similar barrier as Usagi, she was breathing and was clearly an Ascended. So began the cycle of attempted to escape and recovering from her failure.

The monotony of this was broken by the arrival of Eris. Seiya attacked Eris in an explosion of pent up frustration and demanded that she tell her what was going on. Her capture revealed herself to be Rhadamanthus containing Usagi forced her to stay still, but now that Eris was there to help she could finally move. She told the angry Seiya that Usagi was just being contained until the others arrived so that she could be judged. She then left Eris to explain the rest.

It turns out that she had been locked up as well for what she had done, and only now broke out, though she was stuck there until the judgement was complete. While, uncertain whether to trust Eris or not, Seiya was at least happy that Usagi was alright. Only to become horrified that despite appearing to be unconscious she was fully aware of everything that was going on outside of the barrier she was placed in.

Seeing how Seiya had noticeably paled Eris correctly guest that she had spilled her guts when she thought Usagi was asleep. Seiya’s anger returned thinking that Eris had manipulated this to happen. Eris had expected Seiya to be imprisoned like Usagi, so this was justa lucky accident. She explained that she wanted Terra who Seiya knew as Mamoru back. They were together for nearly 30 thousand years, before Cosmos took an interest in him. Now that she was awakening Eris saw this as a chance for them to finally be together.

Seiya was the perfect wedge to be put between them, while they were as developed as her love for Mamoru Usagi did have feelings for Seiya. Ignoring Seiya Eris started talking directly to Usagi asking her if it was actually her or Serenity who loved Mamoru. Seiya dragged her away from Usagi and she let the matter drop. The two went for a walk as Eris explained what was going on.

At Quaoar's request the senshi had been invited to speak on her behalf, though the final decision was up to the Ascended. The ascended unanimously agreed to let Usagi go. They decreed that they will continue their pact of noninterference. Usagi must be allowed to discover her powers on her own. Them interfering could simply slow that process down, and potentially lead her astray. However, since the senshi were now aware of them, the block on contact was removed. All Ascended Senshi will be allowed to converse with them normally. They may not, however, use their powers to knowingly help or hinder any Senshi within this star system, save in their own self defense.

Because she was ascending a replacement for her had to awaken on Kinmoku. She was planning on going back anyway only to be told that if she wasn’t near enough to Usagi, the process could stall. This also means the senshi would be around to protect her against any creature looking for a meal. Since the process could take years at least she needed a place to stay. Setsuna ended up offering her a room at her place.

Seiya quickly began to feel that it was to stop sponging off of Setsuna, unfortunately she had no particular ideas as to what to offer. Her thoughts on this, were quickly tossed aside when she returned to her room only to find Eris moping on her bed. She had been getting no where with Mamoru and wanted someone to talk to. While a strong temptation to send the woman away briefly flashing through Seiya’s mind, she dismissed it quickly realizing that Eris hasn’t actually done anything wrong.

Seiya agreed to talk only to be told that due to promising not to interfere in Usagi's love life Eris couldn’t really talk to her. A frustrated Seiya asked Eris what did she want to talk about only to be told she didn’t know. So they ended up talking about Seiya’s problems. She couldn’t go back to her old life as that would lead to loads of questions from the press especially with the other starlights not here. Eris suggested one of the parties she did reveal her identity to could help her get a job. This caused Seiya to think she was trying to manipulate her into getting into contact with Usagi, but the thought never crossed her mind even if she did admit that it would be a nice side benefit.

Seiya called Eris out for her constant scheming only to be told she hates lies, self-serving lies, lies of omission, white lies... it doesn't matter. I hate when people aren't honest. Seeing Seiya’s confused look she challenged her to think of a time she had lied. While Seiya conceded her point she pointed out that the mask Eris wears could be considered a form of deception. Eris conceded as well and removed it shocking Seiya by revealing that she looks just like Usagi.

This led to a discussion about the the nature of the ascended causing Seiya to ask when she’ll know it is happening to her. Eris first that she will here voices that slowly become more and more coherent before merging into one voice. Eris told Seiya about her own experience of this happening, until she got so frustrated that she told it to shut up. This led to the revelation that it was the planet speaking to her, urging in its own way to embrace the truth about herself. After she grasped that, the power started coming quickly as she threw aside any vestige of the untrue self. She advised Seiya not to put much stock in that element though she could have a more physical aspect then Eris.

Seiya then asked about Orcus and why she hated Usagi only to be told that she didn’t, in fact she worships Cosmos. The seeming hatred was just her aspect coming through. Eris was about to leave only for Seiya to decide it was her turn to talk. She suggested that Eris consider a compromise in her attempt at being with Terra. In response Eris’ eyes grew cold she put her mask back and vanished after saying that neither she or Cosmos would compromise.

Seiya was brought out of her boredom by the arrival of Usagi and the two exchanged awkward small talk where Usagi suggested that she ask Kasumi for a job. She found out that Seiya was where Eris went after she left and Seiya told her about how the two look alike as well as how Ixion and Mamoru look alike. With this Usagi told her that Mamoru was coming back to Japan and asked her if she was okay with the way things were. Seiya assertion that she was only made Usagi frown; she remembered what Seiya told her on the moon. While Seiya did still want to be with Usagi she just couldn’t ignore everything else and didn’t want to get between her and Mamoru. She let out a small laugh when Usagi mentioned how love between the star seed bearers is eternal realizing she was suggesting the same thing she suggested to Eris.

Unlike Eris she didn’t think it was impossible, but asked Usagi if she really wanted to go down that path. Given how complicated her life already was Usagi didn’t really think it mattered. Since they were going to be around each other a lot more Seiya decided she should consider that job. As the two were heading to the restaurant Usagi asked Seiya if she could still transform. Seiya told her that she didn’t mind transforming into a man for her. However Usagi having thought about this a lot realized that at least with Seiya she didn’t care.

Frost was able to fix Seiya and Usagi’s armor after she returned from her training and rescued the others from Togenkyo Island. While they were happy with the results Seiya knew there had to be a catch. Frost explained that due to the change in energy cores Seiya could only run at 90%, as she continues to ascend it should eventually reach equality, but it will take awhile.

As for Usagi defensively her armor is stronger then it was before and while there is an upper limit, its regenerative properties should overcome that. Unfortunately all of Sailor Moon’s offensive attacks is powered by the Ginzuishou, so since its been destroyed she has to go back to using her tiara. While annoyed at having to use an attack she hasn’t relied on in ages Usagi knew accepted as it was better then nothing. Frost also informed her she had a sonic attack. While Usagi remembered using supersonic waves she had no idea how to activate it, Makoto could shrug when she looked at her.

Frost had found a few other functions that had been deactivated for some reason. Though the only one that would work with the new core was the invisibility function. However when they tested it out it turned that it only turned her clothes invisible leaving Usagi in her underwear. After that they felt it west best to keep the other functions off as well. Frost assured a flustered Usagi that there were no other surprises. With that out of the way Frost finished her examination Usagi didn’t have any power fluctuation other then a few instances. Due to her embarrassment Seiya and Makoto explained that she had gotten everyone drunk. Frost could only guess what prompted that, but the others gave no further clarification.

Makoto brought up how it made them aware of Shampoo’s issue, though they felt it was up to Shampoo to explain. Seiya decided to get back to work and soon the party broke up, leaving Frost in the dark.

## Abilities

Due to the energy she was exposed to when Usagi broke her star seed Seiya has begun the process of becoming an Ascended Senshi. However while she has gained a lot of power, until they have fully formed she has no way to utilize it.
