CARDwith SP Robin & Hyacine rerun dual banners launching together
The Thousand Stars City is about to open, the summer-limited SP Robin has arrived, and Hyacine's rerun banner is also being served up together. Veteran players from 1.0 to now should remember that every year, the summer event version has miHoYo throwing in something "different"—not just a new map and new characters, but changing the entire tone of the version. This year, it's Thousand Stars City's turn—the Interastral Peace Entertainment headquarters, IPC territory, an area where you can feel "this place is rich" just by looking at the concept art.
If you're still torn about whether to pull and which one to pull, this post will help you sort out the version's core content in one go. Including banner logic, character versatility, rerun value, and details worth paying attention to within the version!
4.5 Version Core Info at a Glance
Update Date: August 26, 2026
Version Name: "Chips Thrown for a Thousand Stars"
Core Stage: Thousand Stars City — Interastral Peace Entertainment (IPC) headquarters, a brand-new exploration area. Based on the footage shown in the preview, this is an urban area with a pronounced vertical structure—layered, neon-lit, and completely different in style from the Xianzhou or Belobog.
Banner Schedule: Double new 5-stars + double reruns, split across the first and second halves to suit different needs.
| Banner Schedule | New Characters | Rerun Characters |
| First Half From Aug 26 | Robin · Sunny Melody (5-star · Wind · Remembrance) | Hyacine (5-star · Wind · Remembrance) |
| Second Half From Sep 12 | Aventurine · Waveplay (5-star · Quantum · Joy) | Immortal Path |
Robin · Sunny Melody and Aventurine · Waveplay are both 5-star limited characters—not skins, but independent new forms that require separate pulls. Their roles and use cases are completely different. The time gap between the first-half and second-half banners is nearly three weeks, which is enough for you to decide whether to keep investing in the second half based on your first-half pull results and actual gameplay experience!
SP Robin: Versatile Action-Advance Sub-DPS, Not Tied to Remembrance Teams.
Robin · Sunny Melody is positioned as a Wind-element Remembrance-path support character who can summon the memosprite "Sunny Songster" to assist in battle. Based on V3 data, her versatility is broader than expected—she is not forced to be tied to Remembrance teams and can fit into many existing team structures.
Core Mechanics:
When allied characters attack, heal, or apply shields, Robin gains "Atmosphere Value";
Her Skill can directly summon the memosprite bird; when Atmosphere Value reaches 12 points, all three birds are present, entering "Fever Mode";
During Fever Mode, the entire team receives buffs, and Robin's memosprite assists in attacks, dealing AoE Wind damage to enemies;
The background music switches to Robin's new song "Only Chase the Direction of the Wind"—an in-combat BGM change that fully immerses you in the experience.
Differences from Original Robin:
The original Robin is Physical Harmony, focusing on team-wide action advance and ATK buffs, more of a "team action accelerator." SP Robin, on the other hand, is Wind Remembrance, centered around summon mechanics and leaning more toward "sustained buffs + extra damage." They are not direct upgrades over each other—they serve different niches.
Versatility Analysis:
Her mechanics do not force her into Remembrance teams—she is a versatile action-advance battery sub-DPS. Based on the official reference team compositions, she can replace Sunday or the Remembrance Trailblazer, indicating that her role is a "flexible plug-in" rather than a "fixed puzzle piece."
Official Reference Teams:
Castorice + Mydei + Robin · Sunny Melody + Hyacine (replacing Cyrene's teamwide buff slot)
Mydei + Cyrene + Robin · Sunny Melody + Hyacine (replacing Remembrance Trailblazer's action-advance slot)
Himeko · Voyager + Robin · Sunny Melody + Welt + Huohuo (replacing Sunday's action-advance slot)
Hyacine Rerun: A Key Piece for Remembrance Teams—Worth Pulling?
Hyacine is the rerun character in the first-half banner, a 5-star Wind Remembrance character positioned toward sustain and buffs. Her core value lies in providing stable teamwide buffs and survivability for Remembrance teams. If you plan to pull for SP Robin in the first half, Hyacine's concurrent banner means you can plan resources for both Remembrance-path characters at once—without waiting for the second half. This is a hidden advantage of the first-half banner.
Hyacine's Value in Remembrance Teams:
She is not an absolute necessity for Remembrance teams, but if you plan to build a complete Remembrance team system, she is a reliable and stable choice. Compared to other sustain units, her advantage lies in her more direct synergy with Remembrance-path characters and better integration with memosprite mechanics.
SP Aventurine: DPS for the Joy System, E2 is a game-changer.
SP Aventurine is the new character in the second-half banner, a Quantum-element Joy-path DPS whose mechanics are deeply tied to "Aha Moment" and follow-up attacks. He is completely different from the original Aventurine—the original is Preservation, providing shields and protecting allies; the new version is Joy, focused primarily on dealing damage.
Core Mechanics:
After allies use attacks, Aventurine gains "Fervor"; at 10 stacks, automatically triggers a Joy skill;
Under the "Good Show Deserves a Reward" state, his Skill and Ultimate deal additional Quantum Joy damage to all enemies;
Talent "Surfing the Surging Waves": When there is a Joy-path character in the team, all allies' Joyfulness increases.
Key Constellations:
E2 is the game-changer—raises the Fervor cap to 50, allowing more frequent triggers;
E1 provides +24% All-Type RES PEN.

Final Words
The core highlights of version 4.5 are really just two things: Thousand Stars City and SP Robin.
Robin's versatility is higher than expected—she doesn't have to be tied to a Remembrance team to be viable. If you plan to get her, it's recommended to plan your resources alongside Hyacine's rerun during the first-half banner. The second-half banner features Aventurine · Waveplay taking over, so Joy-system players can prepare in advance. The version lasts 35 days, so there's plenty of time—no need to go all-in on day one. Plan carefully before pulling, which is far safer than pulling blindly.
