HSR 4.x New Characters in Planarcadia: Aha’s Elation

Hey, Trailblazer! HSR 4.x is where Aha stops being a background menace and starts being the headline: Planarcadia rolls in, Elation gets the spotlight, and a whole batch of new characters (plus Aha-stamped variants) are ready to turn combat into a comedy routine.

So if you’re hunting every new character in this Elation wave, this guide breaks down the roster with lore context and the most grounded playstyle reads we can make.

What is Planarcadia?

Planarcadia is the Astral Express’s next big Trailblaze destination in Version 4.0—basically Aha’s Elation-themed playground, where “reality” feels like it’s part of the punchline. In the official tease, the Express even has history here: it once crashed into Planarcadia and then departed, and now the wider “threat of Destruction” has the whole cosmos paying attention to the Aeons again. Aha’s “reward” is deliberately ridiculous: join THEIR game and “become an Aeon for a minute.” Expect a stage-like world full of pranks, Masked Fools vibes, and Elation mechanics that echo SU’s follow-up/extra-damage identity.

So yeah—Planarcadia is basically Aha saying “welcome to my show.” And like any good show, it needs a cast. The teasers gave us a handful of faces already, from familiar troublemakers to brand-new wildcards—let’s break down who they are and what their vibes suggest in combat.

 

All New Planarcadia Characters

Yao Guang — “Prosper: Aha”

Rarity: 5-Star | Element: Physical | Path: Elation

Yao Guang is the serious kind of scary: an Arbiter-General of the Xianzhou Yuque and the “Seer Strategist” who reads fortune through the Hunt’s “eye,” yet still chooses to step into danger herself. She’s also not brand-new out of nowhere—she’s been tied into Xianzhou politics and the Luofu storyline beats in earlier narrative mentions.

In gameplay, she plays like a “calm setup, sharp punchline” Elation carry: she lays down a field that turns the team’s attacks into extra Elation hits, builds stacks off your tempo, then cashes them out with a big finishing burst when her window is ready.

 

Sparxie — “YOU’RE the Aha”

Rarity: 5-Star | Element: Fire | Path: Elation

Sparxie is Planarcadia’s No.1 highlight-reel machine—a high-energy streamer who talks like chat is flying at light. She’s a 5★ Fire character on the Elation Path and a member of the Masked Fools, which already tells you her whole brand: performance first, rules second. And yes—she’s explicitly framed as an alternate take on Sparkle, so expect the same “role-playing gremlin” DNA, just turned up for Aha’s stage.

In gameplay, that showtime energy translates into a SP-hungry Elation damage loop: she spends points to build her “Punchline” momentum, then fires off encore hits and quick cash-outs when the hype meter is primed—very much “chat goes wild, numbers go brr.”

 

Evanescia — “Who Is Aha”

Rarity: 5-Star | Element: Ice | Path: Elation

Evanescia screams “Planarcadia’s signature mischief unit”: the tagline is a wink at Aha’s whole “don’t ask, just play” energy. Visually, her sakura-miko styling also gives off a familiar Yae Sakura–style vibe for long-time HoYoverse fans—more of a fun homage than a direct link.

Playstyle-wise, I’d expect a vanish → reappear rhythm: she sets up “petal” conditions during normal turns, then cashes them out in sudden, clean bursts that feel like a punchline landing late. Compared to other Elation reads, hers would be more about timed disappearance and delayed payoff than spammy procs.

 

Ashveil — “True Aha”

Rarity: 5-Star | Element: Fire | Path: Elation

Ashveil steps in like a showman called back to the spotlight—“Aha! He’s awake!”—all swagger, no apologies. With that name and stage-ready styling, “True Aha” feels less like a title and more like a warning: he’s the type who treats the rules as part of the performance, then flips them when you think you’ve figured him out.

If Elation’s SU identity is “Follow-up + Aftertaste,” Ashveil’s angle can be randomized spectacle: think marks that “flip” into different bonus hit patterns (the SU Aftertaste idea already plays with random damage types). In other words: not just extra hits—extra hits with “roulette” flavor, bouncing targets or changing the “punchline” based on what got triggered, making him feel distinct from the more orderly Elation kits.

 

Blade — “Glory: Aha”

Rarity: 5-Star | Element: Wind | Path: Elation

Blade getting an Aha-flavored title is funny on its own: this is the Stellaron Hunter who runs on pain and cash-outs, now dragged onto an Aeon’s stage. And the irony hits harder when you remember his Xianzhou roots—his past as Yingxing and the whole High-Cloud Quintet tragedy that still haunts that storyline.

Blade’s existing loop is very defined: he consumes HP to enter a state, converts basics into enhanced hits, builds stacks whenever he loses HP, then cashes out with an AoE follow-up at max stacks. That’s why his “Glory: Aha” SP framing can be meaningfully different: instead of “endure pain to earn payoff,” his SP form likely pushes the payoff frequency (more “encore” moments) and makes the cash-out feel like a stage climax—same DNA, but tuned toward bigger, more theatrical finishers that sit naturally inside Elation’s follow-up-centric identity.

 

Nihilux — “Origin: Aha”

Rarity: 5-Star | Element: Imaginary | Path: Elation

Nihilux gives off “strictest mother of the Aeons” energy—she looks like the type to set rules, scold you for breaking them, and somehow still make it funny. Then her own tagline immediately undercuts that authority with the most relatable flaw: she can preach deadlines all day, but when it’s her manuscript, “on time” becomes a myth. Paired with that manga-panel aesthetic, she feels like someone who writes the script of the joke… and then procrastinates the final page.

Her “Origin: Aha” title suggests she isn’t about flashy randomness, but authoring the trigger itself: she likely sets “frames” (states) that convert normal actions into scripted bonus cuts—clean, repeatable, and very “I planned the joke three turns ago.” That would still align with Elation’s follow-up/Aftertaste philosophy, but in a structured ‘panel-by-panel’ sequence rather than chaos spam.

 

Silver Wolf — “King: Aha”

Rarity: 5-Star | Element: Quantum | Path: Elation

Silver Wolf is also an existing Stellaron Hunter, and her personality is basically Elation-coded already: a genius hacker who treats the universe like an immersive game and plays for laughs. So if Planarcadia is Aha’s playground, she’s the one character who’d unironically say “free DLC?” and dive in.

Silver Wolf’s signature identity is “rule hacking”: she implants a Weakness onto a target (only one implanted weakness can stick at a time) and piles debuffs to make fights behave. “King: Aha” SP reads like the same concept turned from “single-target surgery” into global stage rules: instead of just implanting one weakness, her SP kit likely revolves around cycling ‘bugs’ that change what actions mean (e.g., when a debuff is applied, a bonus hit triggers; when a weakness is present, a second “punchline” instance pops).

 

Conclusion

Planarcadia is Aha’s stage, and the HSR 4.x Elation lineup is the cast—some are brand-new troublemakers, some are familiar names wearing a fresh Aha-flavored crown, but all of them scream “setup → punchline.”

If you’re pulling, plan like a grown-up… and then immediately act like a clown the moment the banner goes live. And if Aha decides your Oneiric Shard is the real joke, a quick top-up on LDShop can be your little “anti-prank” button—fast, simple, and you’re back to rolling for the punchline you actually want!
