Sayu
Who is Sayu?
Sayu is a 4★ Anemo Claymore healer/Sub-DPS from Inazuma, a perpetually sleepy ninja of the Shuumatsuban. Rated C-tier overall but SS-tier for Exploration, she heals through Swirl reactions and her Muji-Muji Daruma Burst summon, while also applying 4pc Viridescent Venerer's Anemo/Swirl utility. Her defining exploration ability is her roll-out Elemental Skill, which turns into a giant spinning ball that does not startle small animals — beloved by fishing and wildlife enthusiasts.

F2P Verdict
Favonius Greatsword provides reliable ER for her 80-cost Burst.
Sacrificial Greatsword resets her Skill for more Windwheel rolls in a single rotation.
At C0 focus on Viridescent Venerer and Energy Recharge; her C1 is required to enable simultaneous heal + attack from the Daruma.

Frequently Asked Questions
How does Sayu heal?
Her Muji-Muji Daruma (Burst) automatically heals the lowest-HP party member at intervals. At C1 it can simultaneously attack enemies and heal. Her EM also scales the healing from Swirl reactions slightly. Source: Game8.
Why is Sayu SS-tier for exploration?
Her Windwheel Elemental Skill roll moves fast, does not consume stamina while rolling, and — crucially — does not startle small animals, making her essential for wildlife-related achievements. Source: Game8.
Does Sayu need C1?
C1 removes the restriction that forces the Daruma to choose between healing and attacking; at C1 it does both simultaneously. She is functional at C0 but noticeably limited. Source: Game8.
What ER does Sayu need?
Around 200% to keep her 80-cost Burst on cooldown in most teams. Favonius Greatsword or Sacrificial Greatsword help significantly. Source: Game8.
