Introduction

Sunna is an S-rank Physical character in Zenless Zone Zero. Sunna's specialty is Support. Faction: Angels of Delusion.

On our Zenless Zone Zero tier list Sunna is S tier, 10th of the 57 characters ranked, from where 8 current tier lists put Sunna.

Other Physical characters in Zenless Zone Zero: Alice Thymefield, Billy Kid, Caesar King, Corin Wickes, Dialyn, Jane Doe and 7 more.

Is Sunna good?

Sunna hands out strong ATK buffs, chips in extra damage through Cat's Gaze, and heals through her Ultimate, all in a kit that's easy to pick up with F2P-friendly W-Engine choices. Ye Shunguang gets the most out of her since Sunna's Ether Veil speeds up her Enhanced State, and she can also slot into an Anomaly team as long as Aria is present to detonate Cat's Gaze.

We rank her S tier; her one real gap is Rupture units, since her kit just doesn't interact with them, and she needs Aria specifically to work in an Anomaly comp.

Pairs well with: Ye Shunguang; Billy; Anby; Dialyn; Aria.

Strengths

  • Strong ATK buffs for the whole squad
  • Adds extra damage through Cat's Gaze
  • Heals through her Ultimate
  • Easy kit to learn with budget-friendly W-Engine options

Weaknesses

  • Doesn't work with Rupture units
  • Needs Aria specifically to function in an Anomaly team

Profile

Sunna is a female Human. Her birthday is July 18th, and she stands 154cm (5'1") tall. Sunna is voiced by Muya Ruilin (木雅瑞林) in Chinese, Alexis Tipton in English, Morishima Yūka (森嶋 優花) in Japanese, and Lee Seul (이슬) in Korean. Sunna was released on 6 February 2026.

Background

Aaaaaah! I'm so—so nervous...

I just wish I could find a way... to make the entire audience disappear!

Sunna is a playable Agent in Zenless Zone Zero, and the composer of the Angels of Delusion.

"Don't worry, I'll give you a boost of I!

DOL! POW! ER!"

NANGONG YU

Nangong, who came running and secretly pressed the cold drink she just bought against Sunna's arm

"Huh? Bubblegum must be pretty happy... right?

I mean, it's always so energetic whenever it shows up...

It's way more spirited than Sunna after she finishes writing a song."

ARIA

Aria, when suddenly asked "Is my virtual pet kitten happy?"

"Hello? The rent for the practice room hasn't been paid this month...

Hey, I can see that the lights are on! Can someone please answer?"

UNKNOWN

Meanwhile, the young lady behind the door had entered a flow state while composing music

"When Sunna sings while playing the piano, you can't help but smile...

Same goes for when she's practicing her dance steps or being forced to wear cat ear headsets."

Their teacher opening up a shopping app while the Angels were immersed in their rehearsals

"Aaaaaah! I'm so—so nervous... I just wish I could find a way...

to make the entire audience disappear!"

Sunna

"Step left, spin to the right, raise my hand...

Huh? Where did I start falling behind the beat again—"

"Ugh, stop laughing! My arms and legs just have a mind of their own..."

"I'll practice it one more time... no, ten more times!

I can definitely do this!"

She moves like a little deer in the mountains, lightly leaping over every hardship, with musical notes rising from where she steps.

Delusions stretch out long, slender branches, quietly binding one person's daydream into a grand story shared by three.

keep humming along and walk forward into this pink-tinted summer.

Sunna keeping her hammer as a sidechain on her backpack while not using it could be a pun on the sidechain (ducking) effect in music production.

Sunna's Mindscape names are likely references to Vocaloid songs and Japanese pop culture:

The name of her M1, Loneliness Corruption Symptoms , is reminiscent of the song "Deathly Loneliness Attacks" by Hifumi.

The name of her M2, Feline Go-With-the-Flow , is reminiscent of the song "At God's Mercy" by rerulili.

The name of her M3, Transformation Apple , is reminiscent of the song "Becoming Potatoes" by Neru.

The name of her M4, Delusion Investigation Team , is reminiscent of the song "Niccori^^ Survey Team Theme" by WONDERFUL☆OPPORTUNITY!.

The name of her M5, Galaxy Tramway , is reminiscent of the 1927 novel Night on the Galactic Railroad by Kenji Miyazawa, which later serves as an improvised inspiration for the famous 1977 manga series Galaxy Express 999 by Leiji Matsumoto.

Various Vocaloid songs make references to the similar-themed distinct novels both in title and in lyrical content.

In addition, the description references the Night on the Galactic Railroad (film) of the novel, with the train passengers being animals.

The name of her M6, Hollow Big Bang , is reminiscent of the song "The Planet Big Bang" produced by PinnochioP for PMaru-sama.

Etymology

Sunna is another name for Sól (Germanic_mythology), the goddess of the sun in Germanic paganism and Norse mythology.

Sunna's name in Chinese and Japanese literally means "thousand summers."

Details

Sunna is a member of the Angels of Delusion idol group and the composer behind all of the group's music. Maintaining top-tier songwriting while keeping pace with rehearsals and stage performances is anything but easy for her. When the pressure piles up, she occasionally employs the tactic of "retreat is the best option" to dodge Captain Nangong Yu's brutal scheduling. Note: Reliable intelligence suggests that this tactic works largely because Nangong Yu intentionally lets it slide. Sunna and Nangong Yu, another member of the Angels of Delusion, have known each other since they were young and grew up together. While they appear to always squabble, the two are in fact deeply dependent on one another. When it comes to music, Sunna shares a strong connection with their final member, Aria. As Aria puts it, the two frequently spend whole days in the studio discussing melodies for new songs, only to drift off to sleep without even realizing it, heads resting against each other. Sunna is fairly introverted and prefers spending time alone over group activities. That said, her two teammates know her weaknesses all too well — she finds it hard to say no and can't handle praise — and are helping her gradually overcome her social anxiety through desensitization training (progress: about 25%). While most fans see Sunna's "hopeless" side as endearing, she herself seems eager to tear off that label and become a confident, "proper idol." As the creative force behind the music, she often wants to flee the stage — yet in truth, she's not as indifferent to performing as she claims to be. Evidence: A sticky note by Sunna's bedside that reads "I can't disappoint the fans. I need to give them my very best on stage!"

Sunna has a weakness for sweets that look cute, which often leads her to buy treats that are all looks and far too sugary — something Nangong never misses a chance to tease her about. Even so, when Nangong and Aria pick out gifts for Sunna, they always settle on cupcakes with colorful, eye-catching designs. Sunna also loves things with gentle, fragrant scents and often makes scented candles herself, as they help her focus her thoughts and spark inspiration. Once she enters her own "musical kingdom," she becomes so absorbed that she can barely hear anything from the outside world. Note: According to Aria, Sunna once burned Nangong's limited-edition teapot dry while writing a song. To make it up to her, Sunna spent more than two weeks serving tea and running errands for Nangong as an apology.

Cooperation Notes:

Belle

Sometimes Sunna reminds me of some kind of rare creature in a game — she only spawns under very specific conditions! Last time, I had to bug her for a whole week just to get her to go clothes shopping with me!

Wise

Yeah, I've had my fair share of Belle's nonstop badgering... I bet Sunna couldn't handle it either.

    Core Skill

    Characters in the Angelic Chord-ination state gain increased ATK, equal to 30% of Sunna's initial ATK, up to a maximum of 525 ATK. When Sunna's initial ATK reaches 1,750, the ATK bonus granted to all squad members reaches its maximum. When attacks from Basic Attack: Naughty Cat Spotted, EX Special Attack: Bubblegum Barrage, EX Special Attack: Special Photography Technique, Chain Attack: Don't Mess With the Cat, or Ultimate: Smash It All! hit an enemy, apply Cat's Gaze to the target for 12s. While Sunna is the currently active character, the duration of Cat's Gaze is continuously refreshed. Some normal enemies affected by Cat's Gaze show reduced aggression toward Sunna. When Attack or Anomaly characters in the squad continuously land attacks on enemies affected by Cat's Gaze, Cat's Gaze is triggered and removed: When triggered by an Attack character, deals the Agent's Attribute DMG equal to 150% of ATK to enemies in an area. When triggered by an Anomaly character, deals the Agent's Attribute DMG equal to 240% of ATK to enemies in an area. This DMG is guaranteed to CRIT, and the CRIT DMG is increased by 80%. DMG dealt by Cat's Gaze is treated as DMG dealt by the triggering Agent. When multiple enemies on the field have Cat's Gaze, only the primary attack target's Cat's Gaze is triggered. Upon triggering, Cat's Gaze is removed from all enemies on the field. When an enemy is Stunned, the number of attacks required to trigger Cat's Gaze is significantly reduced.
