About this atlas

An independent fan research project exploring publicly documented Hololive collaborations, named duos and units. It is not affiliated with COVER Corp.

Research coverage

The selected roster contains 80 Hololive talents, including alumni, former members and affiliates, plus 7 optional mothers shown as family guest talent nodes. The roster snapshot is dated 3 October 2026; historical roster records were updated on 6 October 2026 and relationship evidence on 7 October 2026. The dataset contains 160 relationship records backed by 286 primary and 3 secondary source records. Two records describe different dated casts of holoWitches.

This is a researched selection. Missing ties mean incomplete research, not an absence of relationships. Current activity is not implied by a talent being listed.

• Include Hololive moms enables Pekomama, Mamatsuri, Mamatori, Mama Mori, Mamarissa, Mama Lillie and Mami Shella. The Hololive moms group is a browsing category, not an official generation. Family edges identify public mother–daughter relationships; guest streams are dated coappearances. Moms use sourced character artwork from debut streams, collaboration thumbnails and credited artist posts. Shella’s introduction and the Marine birthday collaboration use explicitly labeled secondary reporting.
• Mel and Rushia retain historical cohort membership with contract-termination dates. Include former members controls their visibility along with alumni.
• Fubuki belongs to both Gen 1 and GAMERS. Selected cohort views place her in that cohort; the overview retains one identity with both affiliations. Council, Project: HOPE and Promise have related-cohort navigation while preserving historical membership: Sana remains in Council.
• Gen 1 includes the evidenced Natsuiro Fubuki collaboration.
• Gen 3 includes six documented pairs and a partial Shiraken unit. A partial unit retains its complete membership in the source panel.
• Generation membership, music credits and proximity on the graph do not imply friendship or romance.
• A multi-member unit is shown through a unit node; it does not create a friendship between every pair.
• Dates describe the documented evidence. Historical collaborations remain visible without implying continuing activity.

Download the Japanese-name discovery audit. It records primary verification, complete memberships and remaining alias uncertainty; one trio retains expressly provisional names. The 7 October audit covers selected recoverable wiki tables and reader candidates; the full legacy index could not be inspected. The four cross-agency connections added in PR #11 are excluded from the atlas; their evidence and complete lineups remain in this audit. Unsupported claims stay outside the graph; provisional performer-used names carry an explicit label.

Download the Holodex discovery audit. This records ten additional primary-supported collaborations, their complete lineups and the indexes used to discover them. Later Sora cross-agency units retain complete guest names and official-profile links in the source panel; guests remain outside the selected Hololive portrait roster, and the graph labels partial lineups.

Download the Tokino Sora discovery audit. The dedicated audit adds 28 primary-supported records, expanding Sora’s recorded connections from 3 to 31. It covers JP, ID, EN and historical external collaborations, with complete dated casts and Hoshimatic Project lineups. The ledger retains unresolved names and inspected coappearances that do not establish a unit. Holodex archive sampling is bounded; this is not Sora’s complete collaboration history.

Using the map

Choose a cohort, talent, unit or topic. Automatic layout uses fCoSE to spread connected clusters; circular and cohort-grid alternatives are available. Dense graphs can still have crossings. Select a connection for its sources, or use the searchable directory for keyboard access. Fullscreen provides more room; its Details button opens the source panel.

Choose Default or a Holodex palette under Light themes or Dark themes. Your choice is remembered on this device. Saved map images use the active theme’s background and label colors.
