Stellar Affinity Delia (黛莉亞) Guide

Steam-city craftsman — machines, ship work, and how to seat her after Light Festival.

Stellar Affinity Delia Guide

Delia (黛莉亞) is one of the four Hime Bond girls officially spotlighted before Stellar Affinity launched on EROLABS (29 July 2026). Partner press — including the 22 July 2026 LDPlayer / PChome feature — calls her the craftsman of a steam city: she forgets the room the moment a wrench hits a panel, stays cheerful, and thinks with her hands first. This page is the captain’s roster card for mid-August 2026, after the Light Festival window closed on 12 August maintenance.

We do not invent skill multipliers. Match portraits and icons in your client. Romanizations drift across EN, Korean 성간의 유대, and Chinese 星慾姬絆 posts — lock the face, not the spelling.

Treat that table as lore plus dating tone, not as a hidden S-tier stamp. Delia’s value on your account is the seat you write: Core, Flex, Bond-only, or Bench. Rules match the Isuna autopsy so limited FOMO does not invent a second economy.

Why she matters after 16 August 2026

Quiet weeks after a festival are when craftsman fantasies get over-funded. Captains see a girl who “fixes the ship” and dump divine artifacts into her because the story says she loves machines. That is backwards. Artifacts exist to clear docks. If Delia is not in the squad that actually undocks, she is a Bond-only project — gifts yes, limit-break mats no. Use this mid-August test:

  1. Does she start your next hard stages attempt?
  2. Does her affection visibly feed energy you convert this week (artifacts & energy)?
  3. Would stealing story free 6★ mats from the written carry change a wall you can name? If the answers are no / maybe / yes, keep her on gifts & dating and the bond checklist as Flex or Bond-only. If the answers are yes / yes / no, promote her and follow progression.

Suggested archetype (verify in-client)

Official copy never prints a damage formula. The steam-city craftsman fantasy suggests idle-battery or module-synergy flavor — a girl who looks like she belongs next to conversion menus. Do not spend tickets to “complete her machine kit” until a real node proves the job. Score her with the roster checklist and the tier list method: clear speed, check survival, bond friction, artifact hunger, opportunity cost. Pairing ideas to test, not dogma:

  • Flex next to a story free 6★ carry from story six-star if she only fills a support seat.
  • Bond-catalyst lane if her Talk / Gift / Mission ticks are cheap and her combat seat is empty.
  • Bench if she arrived as a login shard pile and never entered best teams.

Bonds and dating notes

Partner text leans physical curiosity — Cumpanion-flavored dates more than stern administrator lectures. That does not mean you skip Hime Bonds. Run both tracks on Core/Flex only. Spray gifts because “she likes tools” is how currencies die. Route leftover carnival or residual shop gifts through gifts & dating.

Pull and investment rules (post-festival)

  • Newbie recruit: Only lock Delia if she is the written carry, not because the dossier was cute.
  • Login ~200 campaign leftovers: Bank toward a named gap on summon priority.
  • Isuna leftovers: Do not melt the F2P plan gem floor to “finish” Delia copies on a closed festival week.
  • Story mats: Story six-star owns the designate. Delia does not steal that pipeline unless she is the designate.

Fifteen-minute Delia session

  1. Open roster sheet → write Core / Flex / Bond-only / Bench.
  2. If Core or Flex, one Talk + one Gift on the bond checklist.
  3. Convert energy only into modules she actually wears.
  4. Run one dock from planet walkthrough or combat & idle.
  5. Close the banner UI. Mid-August is for walls and idle parks, not curiosity ten-pulls. Delia’s official dossier is a dating brochure. Your dock logs are the build guide. Believe the logs.
FAQ

Frequently Asked Questions

Quick answers to the most common questions.

Is Delia a launch limited like Isuna?

Partner dossiers listed her as a featured Hime Bond girl, not as the Light Festival rate-up. Confirm her current recruit lane in-client and on [current events](/events/current/).

Should I raise Delia because she 'fixes the ship'?

Only if she sits in a written combat or energy seat. Lore is not a [progression](/builds/progression/) ticket.

Do her dates replace Hime Bonds?

No. Run spiritual and physical tracks together on Core/Flex — [Hime Bonds](/guides/hime-bonds/) and [Cumpanions](/guides/cumpanions/).

Can story free 6★ mats go into Delia?

Only if she is the written designate. Otherwise keep that path on [story six-star](/guides/story-six-star/).

Where does she rank?

Score her live kit with the [tier list](/characters/tier-list/) method. We do not invent numbers from press bios.
