Nomenclature & Etymology[]

Etymology[]

Her first name "Kou" means "light".

Her surname "Seiya" means "star field" or "field of stars".

Appearance[]

Civilian[]

Seiya has blue eyes and long, hip-length raven hair that he keeps tied in a low ponytail. As the leading vocalist of the Three Lights, Seiya is commonly seen wearing a red formal suit jacket with a navy blue long-sleeved button-up shirt underneath with a yellow long tie at the collar, red formal pants, and black shoes. Seiya also wears a pair of silver moon earrings on both of his ears. He sometimes handles the red rose during concerts or as a weapon; for example, he throws the rose at Sailor Tin Nyanko to rescue Eternal Sailor Moon from getting her star seed.

When he studies at Juban High School, he wears a different school uniform, like Taiki and Yaten, to differ from the other male students.

He also wears various casual outfits when he hangs out with Usagi, retaining wearing his silver moon earrings except for in his athletic attire.

Sailor Starlight[]

As Sailor Star Fighter, her height falls in the middle of the other Starlights. Like the other Starlights, her male civilian identity changes to her female identity during her transformation.

Her sailor uniform, identical to the other Starlights, is a black two-piece outfit, consisting of a bikini-like top and hotpants. She wears knee-length boots and elbow-length gloves. She wears a golden beaded tiara, beaded belts on her waist and golden star earrings. Her secondary color is light blue. She also wears a light blue belt-like choker and belt-like straps on her upper arm.

Personality[]

Seiya's personality is considerably more lighthearted than that of the other two Starlights, with a slight prankster edge to his character. He's more willing to become close to Usagi and her friends than the other two Sailor Starlights, and is eager to flirt with both Usagi and Michiru. As mentioned by Taiki and Yaten, Seiya is a sore loser. He doesn’t mind killing bugs, unlike the main girls. Just like the other two Starlights, Seiya is deeply loyal to Princess Kakyuu, becomes an idol and pours his feelings into their songs to search for her, sobs when she dies, and is eager to spend his life with her once the problems on Earth have been resolved. These feelings are paralleled to his feelings for Usagi; Seiya throws himself in harm's way to save Usagi on multiple occasions, to the dismay of his Starlights, and promises to sweep Usagi away and take her throughout space before taking the promise back.

Information[]

Seiya is first seen walking past Mamoru and Usagi at the airport when Mamoru is departing for America. His attention is caught by Usagi, but then he walks away. He later sees Usagi at a shooting location and recognizes her when she’s trying to get a good look at what's happening. He first officially meets Usagi in Episode 173 while Kou Taiki is having a shoot with an actress (as Usagi doesn’t recognize him from the airport). When Taiki's partner and actress turns into a Phage by Sailor Iron Mouse, the trio transform into their Sailor Starlights form off-screen, and she snaps her fingers when Eternal Sailor Moon fights off the Phage. They try to eliminate the Phage, but Eternal Sailor Moon tells them not to hurt the Phage and that the actress is the same person, which creates a glowing Crescent Moon on her forehead. She manages to heal the Phage with Starlight Honeymoon Therapy Kiss. The Sailor Starlights become her rivals. After this, Seiya flirts with Usagi.

As time passes and this flirting continues, Seiya and Usagi eventually become friends, and then Seiya asks Usagi out on a date, during which the two argue often and have a good time, and Seiya almost realizes Usagi is Sailor Moon. Seiya develops feelings for Usagi. Seiya becomes overprotective of Usagi, even to the point of being kicked out by both Taiki and Yaten for his actions. When Sailor Tin Nyanko targets Usagi for her star seed, Seiya along with Rei, Makoto, Minako, and Ami search for her. By the time Eternal Sailor Moon defends herself from being attacked, Seiya saves her by throwing a red rose and injures Sailor Tin Nyanko, which causes Usagi to mistake Seiya for Tuxedo Mask. Seiya angrily tells her that if she tries to attack her, he will stand and fight as he transforms into Sailor Star Fighter and unleashes her Star Serious Laser at Sailor Tin Nyanko, allowing Eternal Sailor Moon to hit her with Silver Moon Crystal Power Kiss. Afterwards, Usagi finally breaks her happy demeanor and reveals that Mamoru didn't respond to any of her calls and messages. Seiya comforts her and asks, "You've still got me... am I not good enough?"

After Princess Kakyuu is killed, she teams up with her fellow Sailor Guardians and attacks Galaxia, standing beside Eternal Sailor Moon to protect her. During their last defense the trio protect Eternal Sailor Moon, only to witness Eternal Sailor Moon attempt to heal Galaxia with her Silver Crystal, allowing Galaxia to forcibly take Sailor Moon's Star Seed.

The Sailor Starlights watch the confrontation between Princess Serenity and Galaxia in the remainder of the final episode. After Galaxia is healed, Sailor Star Fighter and the other Star Lights are overjoyed to see Kakyuu's been brought back to life. Afterwards, Seiya finally says goodbye to Usagi. He also tells Mamoru to protect her before he transforms into Sailor Star Fighter with Sailor Star Healer, Sailor Star Maker, and Kakyuu, and leave Earth to restore their home-world.
