Stellar Affinity Cumpanions Guide
Physical companion routes that deepen the ship’s affection-powered energy loop.
Official Stellar Affinity copy splits intimacy into spiritual Hime Bonds and physical Cumpanions. After the 29 July 2026 EROLABS launch (also listed as 성간의 유대 / 星慾姬絆), captains who only raise one side stall either story scenes or combat energy conversion. This page covers the Cumpanions half: when to push three-stage dates, how gifts should be rationed, and how physical routes plug into divine artifacts without turning week one into a gallery speedrun.
If the spiritual track is still confusing, read Hime Bonds first, then return here. For the wider loop, keep how to play nearby.
Hime Bonds vs Cumpanions
| System | Fantasy | Typical actions | Payoff |
|---|---|---|---|
| Hime Bonds | Spiritual connection | Talk, light gifts, daily missions | Steady affection + scene unlocks |
| Cumpanions | Physical companion contract | Deeper date stages, premium scenes | Bigger energy spikes + exclusive CG routes |
Both feed the “electricity with love” ship fantasy that becomes divine artifacts. Neither replaces levels, bullet-hell execution, or idle mat harvest from combat & idle. Think of Hime Bonds as the daily charger and Cumpanions as the high-voltage spike when a stage-up lands.
Three-stage dating structure
Launch articles describe three-stage exclusive date stories that move from shy meeting → growing feelings → a deeper physical contract, often with uncensored CG and Japanese voice work on each girl. Practical implications for an account:
- Stage 1 is cheap — clear it on every girl you might main or who appears in early story docks.
- Stage 2–3 cost rarer gifts and time — invest only in mains from best teams and the story free six-star designate.
- Do not unlock stage 3 on five girls during beginner week unless carnival missions literally force breadth.
- Voice pack completeness matters — missing audio is usually an install issue (download & PC), not a hidden affection gate.
- Age verification first — EROLABS adult gates can hide buttons that look like “bugs.”
Daily Cumpanions loop
- Claim login / carnival tasks tied to intimacy (launch rewards).
- Top up the spiritual track if meters are too low to open the next date action.
- Spend high-value items only when a stage-up is one action away — do not drip premium gifts randomly.
- Watch the new scene; then convert surplus energy via artifacts & energy.
- Prove the spike on a planetary node (planet walkthrough) before returning to banners (gacha & summon).
- Tick Talk / Gift / Mission progress in the bond checklist tool.
Inventory and currency rules
Bond gifts are a currency with opportunity cost. Rules from currencies still apply:
- Prefer favorite gifts for mains when the UI shows bonuses.
- Use generic gifts to finish carnival checkboxes on side girls.
- Never bankrupt the inventory for a side girl’s stage 3 while your carry is still stage 1.
- Star-fragment style mail (including ~5000 launch packs) should support the same narrow list as upgrade mats in progression.
- Star diamonds are for deliberate banners or value packs — not for panic-buying every gift skin during a date stage.
Combat payoff expectations
Cumpanions scenes are adult content, but they also exist to justify power spikes in an idle bullet-hell RPG. After a major stage unlock:
- Check whether a new artifact recipe, energy cap, or conversion button appeared.
- Push the planet node you previously failed instead of immediately opening the summon UI.
- If the stage still fails, fix team sustain via team builds before assuming you need another pull.
- Keep idle harvest running so the next intimacy spike has mats ready for upgrades.
Captains who clear stage 3 and then ignore artifacts are collecting CG, not building an account.
Carnival and login synergy
The seven-day carnival often mixes intimacy tasks with clears. Efficient pattern:
- Do Cumpanions stage-ups on the carry the same day you claim login pull tokens, so you remember which girl is the real project.
- Do not spend the ~200 login pull campaign on a girl whose stage 1 you refuse to open — that signals a wishlist without a plan.
- If CBT 200% star-diamond return mail arrives, do not convert it into gift packs until the newbie recruit target is locked.
Privacy and client tips
- On shared PCs, use separate emulator profiles from the download guide.
- Keep the client updated; incomplete voice or CG packs produce false “locked scene” reports.
- If a scene remains locked, check affection tier, story flag, and age verification before reinstalling.
- Patch notes in patch notes sometimes call out temporary scene disables — read before filing a mental bug report.

Frequently Asked Questions
Quick answers to the most common questions.
Do Cumpanions replace Hime Bonds?
No. Spiritual and physical tracks stack. Skipping either slows the energy that becomes divine artifacts.
Should every girl reach stage 3?
Mains and your story six-star designate first. Side girls can wait unless an event or carnival task requires them.
Why is a Cumpanions scene locked?
Usually a missing affection tier, story flag, incomplete download, or age verification — check each requirement in-client before reinstalling.
Where do I track daily intimacy ticks?
Use the [bond checklist](/tools/bond-checklist/) tool for Talk, Gift, and Mission columns across both tracks.
