Support
Soukaku
Member of Section 6
Soukaku is a free A-Rank Ice Support built around one move, Fly the Flag. Fed with 3 Vortex stacks, it gives her up to +1,000 ATK, which she passes on to the next Agent through a Quick Assist, and gives the whole squad +20% Ice DMG. She's one of the best budget buffers for Ice damage dealers, Miyabi first, and still shows up in Shiyu Defense next to Miyabi and Yuzuha. Prydwen rates her T1.5 (at M6), Game8 Tier 1.

Main stats
Substat priority
Stat targets
- 2,500 initial ATK to cap Fly the Flag at +1,000 ATK (with a max-level Core Skill; more ATK is needed at lower Core levels)
- Enough Energy for 3 EX Specials before each Fly the Flag
- HP 10,000+, DEF 800+
- CRIT Rate 50–60%+ / CRIT DMG 100–120%+ only if you want personal damage (optional)
Talent priority
Her Core Skill sets the ATK share (10% → 20% of initial ATK, doubled with Vortex): max it first. Past 2,500 initial ATK, extra ATK is wasted.
Recommended teams
Section 6: Miyabi & Yuzuha
Soukaku's most used team in the current Shiyu Defense. She shares both Miyabi's faction and attribute, and her flag hands Miyabi +1,000 ATK before a fully charged Shimotsuki. Bangboo: Sharkboo (2+ Ice Agents).
Ice: Miyabi & Lycaon
A classic trio that can go very far when well optimized: Lycaon stacks more Ice RES shred and Stun DMG, Soukaku the ATK and Ice DMG. Bangboo: Sharkboo.
How to play
Vortex and Fly the Flag
- She gains Vortex stacks (max 3): 1 per EX Special, 1 per Chain Attack, 3 from her Ultimate.
- Her EX Special (Fanning Mosquitoes) is cheap and can be chained by mashing: 3 quick EXs = 3 Vortex. Skip the slow finishing move by holding Special to go straight into Fly the Flag.
- Hold Special to launch Fly the Flag. With 3 Vortex it consumes them and:
- gives her +40% of her initial ATK, up to +1,000 ATK for 22s (Core Passive at max level);
- gives the squad +20% Ice DMG for 22s (Additional Ability: a teammate sharing her Ice attribute or Section 6 faction);
- puts her in Frosted Banner (enhanced Ice Basic and Dash Attacks).
- Fly the Flag triggers a Quick Assist: the Agent who comes in inherits the ATK buff. Only that one Agent gets it, so it's wasted on off-field sub-DPS.
Rotation
EX ×3 (or Ultimate) → hold Special (Fly the Flag) → Quick Assist into your main DPS. Refresh every ~20s (30s from M1).
"Slowkaku": her EX finisher, Chain Attack and Ultimate are slow. Keep her on the field only as long as it takes to plant the flag.
Strengths
- Up to +1,000 flat ATK for your main DPS, with permanent uptime if managed well.
- +20% Ice DMG for the squad, plus 10% Ice RES shred at M4.
- Solid personal damage and Ice Anomaly buildup for a Support.
- Free.
Weaknesses
- The ATK buff only goes to one Agent, so it's useless for off-field sub-DPS.
- Very Ice-centric: outside Ice teams, Nicole or Lucy are usually better.
- Slow animations make rotations clunky.
