Stellar Affinity Serea (瑟蕾雅) Guide

Serea (瑟蕾雅) is the Hope Hill saint from the official four-girl dossier published 22 July 2026 (LDPlayer / PChome), a week before Stellar Affinity launched on EROLABS (29 July 2026). Partner copy says she prayed and healed a village through a long night, puts other people first, and trips over her own feet while asking if you are hurt. Mid-August 2026 captains should read that as tone — then seat her with the same ruthlessness used on Isuna.

This wiki spells her Serea (also seen as Sereya / Cerea in chats). Korean listings sit under 성간의 유대. Always match the portrait.

Official identity (pre-launch dossier)

Field	Partner text (compressed)
Role tag	Saint / caretaker of Hope Hill
Public face	Gentle, snow-soft, others-first
Private gag	Clumsy; falls; little self-awareness
Bond hook	Care-first intimacy; “are you hurt?” energy
Combat numbers	Not in the press kit — open the client

Sustainer fantasies are the second-most expensive mistake after craftsman fantasies. A saint sounds like a healer. If her live kit is a buffer, a bond battery, or a story-only companion, believe the kit. The roster archetypes exist so you do not buy a cathedral for a girl who never starts a dock.

After 12 August 2026: what actually changed

Nothing about Serea’s lore changed when Light Festival UI closed. What changed is your budget. Residual mail, leftover login tickets, and a still-unnamed next banner (current events) mean every new Core is a theft from the gem floor on the F2P plan. Promote Serea only if she answers a written hole in best teams.

Suggested archetype (verify in-client)

Hope Hill + healing-the-village copy suggests sustain / healer. Test it:

• Attrition walls on hard stages — does she change the death cause?
• Long planet walkthrough routes — do you stop burning revives?
• Idle blocks on combat & idle — does she matter when you are not steering?

If she only changes dating UI, she is Bond-only. If she changes a named wall and you already have a damage carry (story free 6★ or newbie recruit), she can be Flex support. Core is rare: you need both a missing sustain seat and leftover mats after the designate on story six-star.

Bonds without martyr spending

Official dates lean caretaker instinct. That is catnip for gift hoarders. Rules:

• Core/Flex only on the bond checklist.
• Spiritual Hime Bonds and physical Cumpanions both run — the saint fantasy is not a skip ticket for one track.
• Shop gifts after festival close buy carry modules first (items, currencies).
• “She would want me to take care of her” is not a progression argument.

Use gifts & dating when several spotlight girls compete for the same box of presents.

Pull and story-mat rules

Resource	Serea rule
Newbie recruit	Lock her only as the written carry
Login leftovers (~200 campaign)	Bank until summon priority names a gap
Story free 6★	Hers only if she is the designate
Festival residue	Do not “finish Serea” with panic tickets
CBT 200% 星鑽	Still a floor, not a saint fund

Twelve-minute Serea session

1. Write the seat.
2. Screenshot the kit next to your current wall’s death cause.
3. Gift only if Core/Flex.
4. Re-test one node. If the death cause is unchanged, demote her before tomorrow’s gifts.
5. Park offline farming so the saint does not eat the whole evening.

Hope Hill is a story. Your gem floor is a plan. Keep them in that order.
