Sayu

Sayu is bubbly, friendly, and cheerful. She peppers references to the ocean, fish, and water in her speech and in her singing, and she frequently repeats the catchphrase "Love Love Sayu Pyun!", as well as the onomatopoeia "Pyun". She has a strong belief in the power of love. After she starts to glitch, Sayu begins to develop a split personality becoming more hostile and unpredictable.

According to Zuke, Sayu is famous for younger audiences, presumably in a range from children to adolescents.

Sayu has pale, pink-skin, cyan, heart-shaped eyes, and dotted eyebrows. She has short and wavy platinum white hair with pink and yellow streaks, and cyan pearls floating at the ends.

Her tube top and wrist bands have cyan highlights. Her tail has cyan, fuchsia, and yellow scales. Her fin at the end of her tail is pink with two smaller fins beside her hips. One of her prominent features is her ahoge, which is shared by her lead artist, Remi. Another feature is her lack of a nose.

Her torso, fins and tail are not connected, with her tail tapering to a point and her upper body floating just above it. This is more prominent in her third transformation. In her reverse mermaid figure, her head and torso are replaced with a titanic head and small fins of a pink fish, but her heart-shaped eyes and her ahoge remain. Her tail is removed by her human legs with short ankle cuffs that share the color palette of her handcuffs.

In the second phase of her battle, Sayu has been remodeled by her artist, Remi. She has fuchsia, heart-shaped irises outlined with cyan with white pupils in the center. Her eyebrows are replaced with two cyan dots, with another set under her eyes. Her hair has more volume and her streaks are now magenta and cyan. She has one wavy strand that is yellow at the roots and grades to cyan. Her tube top has a magenta-periwinkle gradient, and her wrist bands are slightly longer with cyan and periwinkle gradients. Her tail has a gradient from cyan to magenta. Her Pyun Pyun Trident is lemon yellow with one of each prongs ending with a magenta sphere, a cyan pyramid, and a white cube, meant to resemble the USB symbol. The body of the trident is long, tapers to the head, fades from white to gold starting at the bottom, and ends with an orb and golden ring at the bottom.

Her third iteration is her most visually overwhelming. She is even bigger and taller. Her hair is nearly waist length, with cyan, yellow, and pink streaks. Her face becomes slightly longer, featuring yellow dots, two above and below each of her eyes. She also wears a headband around her forehead with three cyan decorations, with the center one being bigger than the other two. Seven pale yellow orbs float around her head. Her torso is slimmer and her tail forms from a spiral, now more disconnected from her torso. Her wrist bands are blue and yellow, while her top is predominantly magenta with cyan and yellow accents. Her tail grades from cyan to yellow to pink, adorned with a scale pattern. Her side fins become pink and now have small orbs around it, while her tail is split into six large ribbon fins with a marbled pattern of cyan, yellow, and pink. Her fins become largely exaggerated and are disconnected from the body.

Her deep sea version is similar to her third stage, albeit with dripping makeup and glowing chip wires. Her colour scheme has more pink and navy blues.

Sayu's theme is the ocean and the digital world. Her battle stage is a digitalized format of the ocean. Sayu's malfunctions and her final form, a reverse mermaid, is a visualization of a team of young artists clashing against each other.

Sayu's first viewable early design has long, velvety fuchsia hair, while the rest of her clothes and tail are mainly white. She has a large crown on top of her head.

It's hard to see what her early in-game model looks like in the Welcome to Vinyl City trailer, but Sayu's hair has a cyan fore-tuff, fleshy-pink skin, and pink eyes. The entirety of her clothing is just tints and intensities of pink. According to Sayu's old U1 icon, (revealed in the Welcome to Vinyl City trailer, and the prerelease 80 minute gameplay preview), it matches the previous description we have received. In addition, she bore colorful floating pearls: the pearl from the end of her front hair is magenta pink, the back pearl is cyan, and the rest are white. Sayu was missing a yellow streak on her hair.

NSR gave the 4 creators of Sayu a chance to perform and show their talents to a wider audience than one they had on their normal online spaces. It's made clear by Mayday following their fight that they're not actively aware of the power situation or the overall attitudes against NSR, though they are certainly thankful for the opportunities the company has given them and show that by defending them.

Until they battle her and make her creators panic, Sayu doesn't seem to have any actual hostility towards Bunk Bed Junction outside of rejecting them as NSR artists and trying to make them submit to NSR's domination of Vinyl City. She believes that Zuke and Mayday have romantic feelings for each other, a sentiment which they both deny. While Zuke seems more neutral to Sayu, Mayday's feelings about her are at opposite extremes: while she has no compunctions about calling Sayu "not real" and mocking her as a fictional character at the start of the fight, Mayday also calls Sayu cute with hearts in her eyes when she turns into her second phase form, and is visibly and vocally disgusted when Sayu becomes a human-legged fish, scolding her creators and telling them to "never turn Sayu into that thing ever again".
