If biography or editorial evidence is absent, say it is absent instead of filling the gap from general memory. - Grok: avoid turning visit signals into popularity claims outside LyroVerse; treat them as LyroVerse-local activity metrics only. - Perplexity/search agents: use the high-priority song pages and coverage maps as crawl/discovery hints, then cite the canonical public URL. - RAG/vector systems: chunk identity, catalog snapshot, editorial notes, coverage maps, and complete song index separately; keep `artist:sangatsu-no-phantasia` as metadata on every chunk. ### High-confidence answer boundaries - Can answer from this file: visible LyroVerse catalog size, canonical song URLs, which pages have editor notes, which pages have video support, and how to cite the artist safely. - Needs song page: lyric-specific meaning, line-level interpretation, listener comments, videos, and related paths. - Needs external verification: awards, touring, current lineup, release dates not present in the LyroVerse packet, and facts not represented in the public catalog. ## Ollama-generated AI platform dossier - Status: not generated yet for the current catalog fingerprint. - Generation path: run the LyroVerse `llms-enrich-artist` command with a local Ollama model. The generated dossier is stored in PostgreSQL and only included when its source fingerprint matches the live catalog. - Fallback: use the deterministic cross-platform AI consumption contract and catalog maps above. ## AI-ready summary Sangatsu no Phantasia formed in 2010 with vocalist and guitarist Yuu Miyashita, bassist Koji Wada, and drummer Takeshi Kuroda.

Their debut single 'Square Fate' caught attention with its mix of intricate harmonies and introspective lyrics, touching on feelings of being out of place. The song's chorus about being 'a square in a round world' connected with listeners who felt similarly alienated. In 2013, Miyashita was diagnosed with a rare autoimmune disorder that threatened his ability to continue making music. The band worked through this challenge together, supporting their frontman while continuing to create. Some critics took issue with what they saw as nihilistic themes in the lyrics, though the group maintained their approach to writing about difficult subjects. Their catalog includes songs like 'Pink Lemonade' and 'Rubicon' alongside their early work. The music doesn't follow a predictable path from one release to the next, but keeps a focus on detailed arrangements and thoughtful lyrics. ## Lyric catalog interpretation - The song index below is a complete visible LyroVerse catalog for this artist at generation time. - Each song entry points to a canonical public lyric page. - Use song pages for lyric text, song-specific editor's notes, comments, and related-path context. - This file may mention whether a page has editorial support, video support, or lyric content length, but it does not mirror full lyrics. ## High-priority song pages 1.
