As a dedicated player of Zenless Zone Zero, I've been eagerly awaiting news on the upcoming 2.6 Path Update. Thanks to trusted leaks, we now have a comprehensive look at Sunna, an upcoming S-Rank Physical Support Agent. While this information is subject to change upon her official release, it provides a thrilling glimpse into her potential role. She is set to debut alongside her colleague Aria as a member of the enigmatic faction, the Angels of Delusion. Her entire design philosophy centers on powerful off-field support, amplifying the damage of Attack and Anomaly specialty allies through a unique system of buffs and debuffs.

Core Combat Mechanics & Skill Breakdown
Sunna's gameplay revolves around two key mechanics: the Angel's Accord buff for her squad and the Cat's Gaze debuff for enemies. Her basic attacks are straightforward, dealing Physical DMG. However, her true utility shines through her more advanced abilities.
-
Basic & Off-Field Attack: Her standard combo unleashes four strikes. When off-field, her companion, Bubble Pop, can automatically attack if no enemy has Cat's Gaze, consuming a resource called [Nail Polisher]. She gains these stacks when any squad member triggers or extends an Ether Veil.
-
Special & EX Special Attacks: These skills summon Bubble Pop to join the fray, dealing damage. Crucially, her EX Special Attack applies the vital Angel's Accord effect to the entire squad for 35 seconds, granting them a significant ATK boost based on Sunna's own stats.

- Chain Attack & Ultimate: These are her high-damage, cinematic moves. Her Chain Attack has her ride Bubble Pop forward for a massive ram, while her Ultimate involves hammer strikes followed by a explosive Bubble Pop barrage. Both provide invulnerability during use and can trigger Quick Assist.
The Heart of Her Kit: Angel's Accord & Cat's Gaze
This duo of effects defines Sunna's support paradigm. Angel's Accord is a powerful team-wide buff. Her Core Passive enhances this, allowing characters under its effect to gain increased ATK equal to 14% of Sunna's initial ATK.
Meanwhile, several of her skills apply Cat's Gaze to enemies for 12 seconds. This mark is the key to unlocking massive bonus damage:
-
When an Attack-specialty ally continuously attacks a marked foe, they trigger the mark, dealing 360% ATK as Attribute DMG.
-
When an Anomaly-specialty ally triggers it, they deal a whopping 480% ATK as guaranteed CRIT damage with +100% CRIT DMG.
This synergy makes her exceptionally potent for teams built around these two specialties. Furthermore, her ability to create and extend Ether Veil effects, particularly Ether Veil: Fantasia Encore, provides another layer of team utility, offering additional ATK and Stun DMG multipliers.

Constellations & Signature Weapon Synergy
Sunna's potential scales dramatically with her Constellations (C1-C6) and her ideal weapon, Song of Thoughts.
Notable Constellation Effects:
| Constellation | Primary Effect |
|---|---|
| C1 | Energy restoration on entry; Cat's Gaze trigger reduces enemy DEF. |
| C2 | Enhances Cat's Gaze trigger speed and damage multipliers for Attack/Anomaly allies. |
| C4 | Team-wide +15% DMG buff after her Ultimate. |
| C6 | Enters a powerful Locked In! state after EX Special Attack, granting self-CRITs, damage reduction, and enhanced Cat's Gaze triggers. |
Her signature weapon, Song of Thoughts, perfectly complements her off-field support role. It provides Energy Regen and, when she uses her EX Special Attack, grants the entire squad a stacking DMG bonus, capping out with an additional ATK increase. This weapon solidifies her position as a premier buffer.
Team Role & Strategic Value
From my analysis, Sunna is positioned as a premier support unit with fascinating strategic depth.
Primary Roles:
-
Amplifier for Attack/Anomaly Teams: She is a versatile cornerstone for teams focusing on these damage types, providing substantial direct damage buffs and triggering high-damage reactions via Cat's Gaze.
-
Ether Veil Enabler: Her kit is tailor-made to initiate and maintain Ether Veil fields, making her an ostensibly perfect partner for characters like Ye Shunguang, who thrive under these effects.
-
Off-Field Damage Contributor: Through Bubble Pop and the Cat's Gaze triggers, she contributes meaningful damage even when not actively on the field.

Final Impressions & Pull Recommendation
Based on the leaked details, Sunna appears to be a robust and strategically valuable addition to the roster. Her ability to significantly boost the output of two major damage-dealing specialties gives her wide applicability. While she seems to have specific synergies with her own faction and characters like Ye Shunguang, her core mechanics are flexible enough to benefit many team compositions. For players looking to enhance their end-game teams, especially those built around Attack or Anomaly carries, saving resources for Sunna's debut in the 2.6 update seems like a wise strategic move. Her diverse gameplay, combining buffing, debuffing, and off-field mechanics, promises to add a dynamic new layer to squad building in Zenless Zone Zero.
