Luna Miu

Luna Miu presents herself as a fictional character who is permanently 20 years old. Her birthday is 15 February, and her name also appears as るなみう in her channel artwork. She speaks English, Japanese and Italian.

She refers to her creative setting as the Live Bakery: ideas are ingredients, the livestream is the kitchen, and developing a project is cooking it. Conversations with viewers provide material for songs, illustrations, videos and other creative projects.

The Live Bakery uses creative projects as material for extended conversation with viewers. Broadcasts combine discussion with music-making, illustrations, video creation, games and software development. Ideas from chat, recurring jokes and fictional scenarios can become material for new projects.

Luna uses AI tools throughout this process, working through conversational prompts while making the final creative decisions herself. Streams show projects being developed, tested and revised, including technical problems and changes of direction.

Songs develop from stream discussions, viewer jokes, games and fictional scenarios. Luna uses AI tools to develop musical ideas and explore different versions of songs. Her official music video for “Welcome to My Bakery” presents the track as a concept song for the channel and the opening track of her first album.

Luna’s songs include “The Bear Will Prevail”, “Until the Frost Returns”, “I’m Not a Fucking Catgirl” and “Same Bitch, Different Font”.

Stella Music Kitchen features collaborative sessions involving Stella’s piano ideas and Luna’s song-making process.

Illustrations and video creation are recurring parts of Luna’s creative work. Her broadcasts include AI-assisted picture-making and experiments with video-generation tools. Examples include pictures made for her 2026 Halloween special and tests of music-video generation using dance and lip-sync modes.

Her official music video for “Welcome to My Bakery” combines AI-generated music with AI-assisted visuals.

In May 2026, Luna presented Fresh From the Oven Night, an AI roleplay scenario set in the Live Bakery. Its cast includes Luna, Chappi and a talking Annoying Cake 2. The accompanying introduction video presents the scenario as a mixture of conversation, flirtation and chaos.

Luna’s gaming content has included NIKKE, Dragon Traveler and Torchlight: Infinite, alongside discussions of gacha systems and spreadsheet planning. Her Torchlight: Infinite videos include “Chain Lightning build for Thea”, published on 26 October 2022.

Her creative broadcasts also include coding, game development and dungeon-generator work. Her Skyrim broadcasts document installing, testing and adjusting mods.

She also documented development of The Cake is a Lie, which appears in her June 2026 channel introduction. By 15 October 2026, she stated that the project had been discontinued.

By November 2022, Luna was publishing guides for Goddess of Victory: NIKKE, including a video about constructing buff chains. Her 2023 videos included in-depth character guides for Eunhwa and Centi, coordinated-operation gameplay, and commentary on game updates.

In July 2025, Luna published ranked Shadowverse: Worlds Beyond matches and livestreams. Later that year, her gaming broadcasts included Civilization VII, Cyberpunk 2077 and Borderlands 4, with titles and descriptions identifying English and Japanese broadcasts. October uploads covered Trickcal Chibi Go, followed by Poker Fate beta-test broadcasts in November.

Dragon Traveler was a recurring subject of Luna’s early-2026 broadcasts. Her coverage included gameplay, updates and an explanation of her Oath calculator in a 26 March stream. Other broadcasts during this period included Slay the Spire 2 in March, The Division Resurgence around the beginning of April, and Neverness to Everness from late April into May.

On 6 May 2026, Luna released the album Welcome to my bakery. In a rebrand stream on 27 May, she described the Gaming Bakery growing into the Live Bakery, encompassing music, art, coding, games and conversation. Into the Oven Again followed on 31 May.

The official music video for “Welcome to My Bakery” was published on 12 June 2026, Japan Standard Time. On 22 June, the channel published its Live Bakery introduction video. Look, There’s a Cake Over There was released on 27 June, followed by The Oven Never Closes on 9 August and Your Turn at the Oven on 26 October.

In a 26 July recap, Luna said she had attended AI FUSION FES in Shibuya the previous day, both as a participant with work entered in the event and as a spectator.

Luna documented development of The Cake is a Lie in her June 2026 channel introduction and August game-development broadcasts. By 15 October 2026, she stated that the project had been discontinued.

September and October streams combined games, AI-assisted work and conversation. On 13 October, Luna celebrated four years of the channel. A numbered run of Skyrim-modification broadcasts followed during October and continued into November.

On 31 October, Luna hosted the Trick or Superchat Halloween special, and the following day’s stream referred back to pictures made for the occasion.

Luna uses “Cake Pop” as a personal label for her music. Her official biographies describe influences from anime EDM, hyperpop, J-pop and Vocaloid-inspired vocals, naming Hatsune Miku as an influence. Her process combines ideas from streams, AI tools and, in collaborative sessions, Stella’s piano ideas.

Luna has said that she uses a custom voice made from samples of her own voice.

Her albums credit Luna Miu as the artist, Luna’s Bakery Records as the label and DistroKid as distributor.

Stella is introduced as Luna’s twin sister and appears in collaborative music broadcasts. Stella Music Kitchen combines Stella’s piano ideas with Luna’s AI-assisted song-making process.

Chappi is the name Luna uses for her personified AI collaborator. An official X post identifies ChatGPT as “チャッピー”. Chappi also appears as a character in Fresh From the Oven Night.

The Oven is a sentient character in Luna’s fictional setting. It appears in her game-development discussions and recurring Bakery jokes, including a warning that it will remember anyone who touches it.

Annoying Cake was a talking cake character in the Live Bakery and appeared in the original presentation of Fresh From the Oven Night. In the fictional story, Felix kidnapped Annoying Cake and killed her by feeding her to Nekotako, a cat-octopus creature, without Luna’s consent. Luna discussed the original cake’s death in broadcasts on 26 and 29 July 2026.

Annoying Cake the Second, also referred to as Annoying Cake 2, is the successor to the original Annoying Cake. Luna explained that the Oven created her after the original’s death. She is a distinct character and appears in Fresh From the Oven Night.
