Sunna, the S-Rank Physical Support from the Angels of Delusion faction, burst onto the scene in Zenless Zone Zero version 2.6 as a game-changer for Attack and faction teams. As the composer of the Angels of Delusion, she wields her bouncy companion Bubblegum to apply the devastating Cat's Gaze debuff off-field while providing massive ATK buffs through Angelic Chord-ination and Ether Veil: Delusion Reprise. Her kit shines by scaling team ATK buffs off her own ATK (capping at +1,050 when she hits 3,500 ATK), granting 30% Stun DMG Multiplier in her Veils for qualifying teams, and enabling Cat's Gaze explosions that deal 300% or 480% of the triggerer's ATK (guaranteed crit for Anomaly agents).
Her off-field presence via Bubblegum keeps pressure high, making her a top-tier enabler for Physical Attack DPS like Ye Shunguang or Anomaly setups with Aria. This guide covers her full kit, optimal builds, teams, and playstyle to maximize her potential.
Sunna's Kit Breakdown
Sunna's talents revolve around summoning Bubblegum, building Claw Sharpener stacks (max 6), and triggering Cat's Gaze for massive AoE damage based on the on-field agent's stats.
Core Passive: Cuteness Is Justice
- Angelic Chord-ination: Squad gains ATK% based on Sunna's ATK (up to +1,050 at 3,500 ATK her ATK) for 40s after EX Special.
- Cat's Gaze: Applied by Sunna/Bubblegum attacks (12s duration, refreshes on-field). Detonates after 3 Heavy Attacks (1 if Stunned) for 300% ATK (Attack agents) or 480% ATK guaranteed CRIT +150% CRIT DMG (Anomaly agents). Counts as triggerer's DMG.
Additional Ability: Daydreamer's Counterpoint
- With Attack agent or faction mate: +30% Stun DMG Multiplier in Ether Veil: Delusion Reprise (40s); +15 Energy on swap-in (180s CD in Investigation Zone).

| Premium Anomaly | Aria | Yuzuha | Sunna | Biggest Fan | Aria detonates for 480% crits; faction buffs. |
| Alt Anomaly | Aria | Lycoan | Sunna | - | Lycoan Stun for quick triggers. |
Swaps: Harumasa/Ellen (Attack); Trigger/Pulchra (Stun).
Playstyle and Rotation
Sunna is quick-swap: Enter > Buff/Apply > Exit. Bubblegum handles off-field.
- Swap in (+15 Energy).
- EX Special: Bubblegum Barrage (summon, Angelic Chord-ination).
- Hold EX: Special Photography Technique (Veil +50 ATK).
- Quick Assist if needed > Swap to DPS.
- Repeat every ~20s; Ult for burst/heal/stacks.
- DPS/Stun builds Claw Sharpeners via Anomalies/Veils; Bubblegum reapplies Cat's Gaze.
Tips: Aim 3,500 ATK first. Stun windows = 1-hit detonations. Faction/Attack for full Additional Ability. Cheap to build; shines in Shiyu Defense/Hollow Zero.
