Pros & Cons for Aoi Kaguragi (The Promising Rising Star)
Can Inflict Windbite
Aoi can inflict Windbite with his Combat Skill. Each time a Kaiju's turn passes, he can deal continuous damage.
Excellent Stacking Buffs
Each time Aoi breaks a Resistance, he gets a permanent buff to his ATK and DEF. It can stack up to 5 times, so try to play in a way that allows you to proactively break Resistance.

Best Team Comps for Aoi Kaguragi (The Promising Rising Star)
Windbite Amplifier Squad Setup
This squad setup uses Chester to significantly increase ATK and enhance Aoi's Windbite damage. Include another attacker to supplement the team's damage, as Aoi's DoT-based damage takes time to activate. Ryo Ikaruga and 4★ Mina Ashiro can also provide ATK buffs, making them strong alternatives to Chester if you don't have him.

Best Skill Enhance Priority for Aoi Kaguragi (The Promising Rising Star)
Recommended Skill Upgrade Priority
| Normal Attack | ★・・・・ |
|---|---|
| Combat Skill | ★★★★・ |
| Ultimate | ★★・・・ |
| Follow-Up Skill | ★・・・・ |
| Passive Skill | ★★★・・ |
The Combat Skill that inflicts Wind DoT on enemies has a high enhancement priority.
The ATK and DEF buffs from the Passive Skill are excellent, but its activation conditions are somewhat difficult to meet, and the HP recovery effect isn’t strong enough to significantly improve survivability, so its priority is not that high.
