Stellar Affinity Guides
Deep tutorials for systems, progression, and planetary adventures.
Stellar Affinity (also listed as 성간의 유대 / 星慾姬絆) launched on EROLABS on 29 July 2026 as an adult anime idle bullet-hell RPG. You captain an ancient ship that, in official framing, seems powered by generating electricity with love. Affection toward the girls aboard becomes ship energy; energy becomes divine artifacts; artifacts swing planetary dock fights. This hub is the map of every systems tutorial on the wiki so you never open five menus without knowing which one actually raises power.
Use English pages first, then jump to characters, builds, items, and events once the loop clicks. Redeem active codes only after you know which currency is tickets versus upgrade fuel.

Launch economy you should respect
Official and partner launch messaging highlighted several free-progression levers that every guide on this hub assumes:
- Newbie recruit rate-up — early summon lane where you lock a preferred crewmate instead of spreading tickets.
- Cumulative login free pulls — reported as up to about 200 pulls across the campaign window, not a single mail dump.
- Seven-day carnival — mission board mixing clears, upgrades, and bond actions.
- 5000 star fragments class mail packs — soft progression fuel; confirm the exact item name in-client.
- Elite CBT 200% star-diamond return — only for accounts that spent during the wipe beta and log the same identity after launch.
- Story free six-star core path — main-dock progress can cultivate a designated girl toward six-star without buying her out of every banner.
Those levers interact. Carnival wants bond ticks while login pulls want a written summon target. Story free growth wants you on docks instead of AFK in the banner UI. Read beginner week before you empty the ticket wallet on day one.
Recommended reading order for new captains
- Download & PC setup if the client is not installed or stuck updating.
- How to play for the affection → energy → artifact → dock loop.
- Reroll only while tutorial tickets are still cheap to redo; stop once bonds and purchases exist.
- Gacha & summon to choose a newbie recruit target against the tier list.
- Hime Bonds and Cumpanions so spiritual and physical tracks both feed the ship.
- Combat & idle to schedule active bullet-hell clears versus offline mat harvest.
- Artifacts & energy when stages stop falling to raw levels.
- Planet walkthrough for dock checklists and wall diagnostics.
- Keep beginner week open as a daily dashboard through day seven.
How systems share one resource budget
Stellar Affinity is not a pure idle clicker and not a pure visual novel. Combat, gacha, and romance systems share attention and mats:
- Bond gifts and carnival intimacy tasks compete with artifact upgrade mats.
- Idle harvest fills inventories that progression priority must spend on a focused core, not twelve girls.
- Banner tickets look infinite during the ~200 login pull window and still evaporate if you chase three rate-ups.
- Planet docks gate story free six-star cultivation; skipping them to spam summons often slows the account.
When a page on this hub links to best teams or team builds, treat that as the next concrete decision after the tutorial concept lands.
Video-backed tutorials
Where a real YouTube capture exists, child pages embed one mid-article facade (thumbnail first, play on click). Launch gameplay footage supports pages such as how to play and download & PC. We never invent video IDs and never stack multiple embeds on one article.
Tools and adjacent hubs

How to use this hub without thrashing
Open one guide fully, finish its checklist, then follow a single outbound link. Captains who skim five hubs usually mis-spend carnival tickets and leave the story free six-star path half-done. Stellar Affinity rewards people who understand why the ship needs affection before they max every slider on every girl.
Return here when a patch adds docks or banners — child guides will update first, and this index stays the routing table.
