Hanya is a Physical-element character who follows the Path of Harmony. She excels at applying the Burden debuff to enemies, which allows allies to recover a Skill Point after hitting the affected target twice or defeating them. This debuff also increases the damage the target receives and enhances an ally’s attack after a Skill Point is recovered through Burden’s effect.

info
Since Hanya's ATK boost doesn't scale with her Max ATK, she should focus on increasing her speed and improving her survivability. To achieve this, 135 SPD is the minimum requirement, and she should aim for at least 4,000 HP and 1,000 DEF to withstand incoming attacks more effectively.
Best Light Cones
SourceLight Cone Event Warp
Capriciousness
Increases the wearer's CRIT DMG by 32~60%. At the start of the battle, the wearer gains Mask, lasting for 3 turn(s). While the wearer has Mask, the wearer's allies have their CRIT Rate increased by 10~14% and their CRIT DMG increased by 28~56%. For every 1 Skill Point the wearer recovers (including Skill Points that exceed the limit), they gain 1 stack of Radiant Flame. And when the wearer has 4 stacks of Radiant Flame, all the stacks are removed, and they gain Mask, lasting for 4 turn(s).This is currently her best 5★ Light Cone. Hanya can trigger its Mask effect, although it may take 2 to 3 turns.

Heir
Increases the wearer's Energy Regeneration Rate by 10~18% and regenerates 1 Skill Point when the wearer uses their Ultimate on an ally. This effect can be triggered once after every 2 uses of the wearer's Ultimate. When the wearer uses their Skill, the next ally taking action (except the wearer) deals 30~50% more DMG for 1 turn(s).This is a good alternative Light Cone that helps make her Ultimate available more quickly.

Solidarity
After the wearer uses a certain type of ability such as Basic ATK, Skill, or Ultimate, all allies gain Childishness, which increases allies' DMG for the same type of ability as used by the wearer by 12~20%. Childishness only takes effect for the most recent type of ability the wearer used and cannot be stacked.This can be considered a free-to-play option for Hanya, as the DMG buff aligns with whichever ability she uses—Basic ATK, Skill, or Ultimate.
