Basic Attack Spread - Single Target, Gold/Water-Gold/Water-Gold/Water Upon 1 Boost, it may probabilistically reduce the target's Yin Defense and will definitely inflict "Delay" status, slowing their actions. Focus - Single Target, Water/Water-Water/Gold/Gold-Gold Upon 2 Boost, it can destroy barriers afflicted with status effects like Poison Cloud/Blind. Additionally, it reduces stats such as Speed, Evasion, and Critical Defense.

Spell Card -Sin "Wandering Great Sin" Single target, Gold/Gold-Gold/Water/Water-Water Damage increases proportionally to your speed. Water-attribute attacks are Yin-attribute attacks, but they have the characteristic of actually being affected by Yang-attribute defense. Before casting, increase your Yang/Yin attack power by 2 stages. After casting, recover 1 of your barriers. -Judgment "King of Hell's Trial" Area of effect, Water/Gold/Water-Gold-Water/Gold This is a debuff-type spell card that shouldn't be expected to deal damage, and it shows its true value at 3 boosts. Immediately before use, it increases your speed, decreases all enemies' evasion, and inflicts blindness status on all enemies. At 3 boosts, it can break through poison mist/blind barriers, and if the enemy's weakness is Water+Gold attribute, it becomes a powerful control skill even at 2 boosts.

Active Skills Skill 1 - Inflicts 'Poison Mist' status ailment on all enemies 3 times, Replenishes 2 Barriers for yourself, And advances your turn order. Skill 2 Decreases the Critical Defense of all enemies, And increases the Critical Attack of all allies in the front row. Additionally, restores 0.5 Spirit to all allies in the front row. Skill 3 Significantly lowers the Yin/Yang Defense of all enemies, And restores 1.25 Spirit to yourself.

Usage Summary Aiki (B3) is a debuff-type character usable in Poison/Blind decks. Since breaking the Poison/Blind barrier requires a 3-boost for the AoE attack, her own Spirit Power might be insufficient alone. It would be even better if you have a character who can restore allies' Spirit Power. (In my case, I equipped Spirit Power recovery spell cards on spells 1 and 2.) Single target damage: Spells 1/3 Area control: Spells 2/4 Finisher: Last Word will be.
