UTAU (utau) is a free Japanese speech synthesizer program created in 2008 as an independent alternative to the paid software Vocaloid. Its name comes from the Japanese word utau (歌う), meaning "to sing."
The program works on a similar principle: the user enters the melody (notes) and lyrics, and the program makes the virtual singer perform the song.

Main differences from Vocaloid:

• Free and open: You can download the UTAU program itself and most of the voices for it completely free of charge.
• Anyone can create their own voice: Unlike Vocaloid, where data banks are created only by large companies in studios, in UTAU anyone can record samples of their voice on a microphone and create their own virtual singer (such a voice bank is called a utauloid).
• Sound Quality: Initially the program produced a more “robotic” and mechanical sound, but modern advanced data banks, when properly configured, sound indistinguishable from a human.

The most famous Utauloids

Since anyone could create characters, thousands of heroes appeared in the UTAU world, but the most popular ones are:

1. Kasane Teto is the absolute symbol of UTAU. Originally created as an April Fool's joke (fans misrepresented her as "the new Vocaloid 04"), the character proved so popular that a voice was created for her in UTAU. Today, Teto is so popular that she performs live with Hatsune Miku.
2. Namine Ritsu – a powerful and incredibly high-quality voice actor. Canonically, he's a six-year-old crossdresser who weighs 25 tons and wears women's clothing, concealing missile launchers within it (a typical example of insane fan humor).
3. Utane Uta (Defoko) is the first and default voice included with the program. Her voice is completely computer-generated, without the help of a human, so she sounds like a real robot.

Rin Kagamine (鏡音リン) is Len's female "mirror half." She was released by Crypton Future Media on the same day as him—December 27, 2007. Her name means "right," complementing Len's name (Left).

Official parameters

• Age: 14 years old (she is the same age as Lena).
• Height: 152 cm (4 cm shorter than Lena).
• Weight: 43 kg
• Zodiac sign: Capricorn (birthday - December 27).

Appearance

• Hairstyle: Rin has short golden-yellow hair (bob-cut). The main detail of her image is a huge white bow on her head, which resembles bunny ears. On her bangs, she wears four thin hairpins (two yellow and two white).
• Eyes: Large, bright blue.
• Clothing: Her outfit mirrors Len's style, but is made in a feminine version. Rin wears a white sleeveless sailor suit with a black collar, a large yellow bow on the chest, black shorts with a yellow belt and a light lace frill, as well as wide black bracers and leg warmers with speakers and equalizers.
• Details: On her left shoulder she has the same red stamp tattoo 02, but with the signature "Rin".
• Main Item: Orange or Tangerine (chosen by fans for its orange-yellow color scheme). Her second unofficial mascot is a giant road roller, which she likes to use to crush enemies in humorous fan animations.

Rin's character

Rin's official character, like all Vocaloids, is a "blank slate." However, over the years of creative work within the community and in official games (such as Project SEKAI), she has developed a very distinct image:
• General traits: She is most often depicted as a hyperactive, cheerful, lively, and stubborn girl. She is incredibly emotional, loves to play pranks, and often leads their duet with Len.
• In songs: Her range of roles is vast. Rin can be a selfish and arrogant princess in the cult classic "The Daughter of Evil," sweet and childishly naive in pop tracks, or a deeply dramatic character in melancholic ballads (like "Regret Message").

• Common fan canon: He's often portrayed as energetic, a bit stubborn, but very loyal and caring. Fan videos often feature him as slightly clumsy or ironically "killed" at the end of tragic music videos (a popular meme in the Vocaloid community).

What is Rin and Len's relationship to each other?

Officially, they are neither twins nor lovers. Crypton declared them to be "one soul reflected in a mirror." The creators deliberately chose not to formalize their status, so that composers could portray them in their songs as brother and sister, mirror twins, friends, or a couple.

Len Kagamine (Japanese: 鏡音レン) is a popular male Vocaloid released by Crypton Future Media on December 27, 2007, along with his "mirror half" Rin Kagamine. Their shared surname translates as "mirror sound," while their given name, Lena, means "left."

Official parameters

• Age: 14 years
• Height: 156 cm
• Weight: 47 kg
• Zodiac sign: Capricorn (birthday - December 27).

Appearance

• Hairstyle: Len has short, unruly golden-yellow hair that is tied into a small ponytail at the back of his head (often referred to by fans as a "pineapple"). He has short bangs in the front and two distinctive long strands on the sides of his face.
• Eyes: Large, bright blue.
• Clothing: His classic attire matches Rin's style and references sailor suits and school uniforms. He wears a white short-sleeved shirt with a black collar, a thin yellow tie, black shorts with a light-colored belt, and glossy black armguards and leg warmers with yellow highlights and images of musical equalizers.
• Details: He has a red stamp tattoo on his left shoulder with the number 02 (as he and Rin are the second couple in the Character Vocal Series). Below the number is the word "Len".
• Main item: Banana (chosen by fans due to his yellow hair color and the resemblance of his hairstyle to a bunch of bananas). The second most common attribute is a steamroller (road machine).

Lena's character

Like Miku, Len doesn't have a single, official character, giving songwriters complete freedom. However, based on thousands of music videos and games (such as Project SEKAI), certain traits have become established within the fandom:
• In songs: He can be anyone from a tragic and devoted servant in the famous "Saga of Evil" ("Servant of Evil") to a daring, hyperactive rapper or a romantic prince.
• Common fan canon: He is often portrayed as energetic, a bit stubborn, but very loyal and caring. In humorous fan videos, he is often portrayed as slightly clumsy or ironically "killed" at the end of tragic videos (this is a popular meme).

Hatsune Miku has a detailed official profile created by Crypton Future Media, though her character is intentionally left open to fan creation.

Official parameters

• Age: 16 years old - she is permanently fixed at this age.
• Height: 158 cm
• Weight: 42 kg
• Zodiac sign: Virgo (birthday is celebrated on August 31 - the day the program was released in 2007).

• Eyes: Large anime eyes that are the same turquoise color as the hair.
• Clothing: Miku's classic outfit is inspired by Japanese school uniforms (sailor fuku) and the design of Yamaha synthesizers. She wears a gray, glossy sleeveless top with a turquoise trim, a black tie, a black pleated skirt, and long, black, over-the-knee boots.
• Details: She has a red stamp tattoo on her left shoulder with the number 01 (her code number as the first Vocaloid in the Character Vocal Series). Her sleeves display a graphical interface resembling a music equalizer control panel.
• Main item: Leek (the unofficial, but most famous mascot attribute of the singer, which appeared thanks to a viral fan video with the song Ievan Polkka).

Miku's character

Miku doesn't have a formal character. The creators intentionally made her a "blank canvas" so that any composer or artist could imbue her with any emotion. Depending on the song, she could be:
• A fun, energetic and sweet pop idol.
• Sad, melancholic, or even creepy (in horror tracks like “Bacterial Contamination”).
• Daring and rebellious in rock compositions.
In popular culture and games like Project SEKAI, she is most often portrayed as a kind, sincere, hard-working girl who loves music with all her heart and is always willing to support other artists.

(a sign of rivalry with Miku or other fan markers).Item in hand: As a weapon or accessory in fan art, she often holds a knife (due to her yandere nature) or a regular cucumber (her official symbolic item).

Vocal Features: In contrast to her aggressive nature, Sukone Tey's voice bank itself sounds surprisingly pure, soft, and feminine.
