Kuro is an Operand Sniper capable of dealing high single-target damage, but sadly, her AoE is quite lacking actually making her one of the more balanced Dolls on this list.
The crux of her damage will come from her Active Skill, while her Passive is essentially filler during its cooldown. Unlike other Dolls on this list so far, Kuro's Active Skill is a 'Continuous Skill', which means that while its active, its cooldown will not decrease until it finishes. This means any Cooldown Reduction effects are only 50% as effective as they normally would be, but at the same time means more emphasis on raw stats can be placed in a build instead. This causes Kuro to be linear and easy to build.
Her Passive gives her Normal Attacks a 60% chance to proc an enhanced shot, which also has a 60% chance to proc another enhance shot. This effect can chain up to 5 times per 1 Normal Attack. The enhanced shot deals 100% Operand, cannot be evade and cannot critically hit normally, but may be able to crit through special means such as Functions and other Doll Skills (like Daiyan).
Kuro's Active Skill is a channeled flurry of shots, dealing 80% Operand every 0.2 seconds for 3 seconds. If Kuro channels the full duration, the target will take an additional 320% Operand damage. The cooldown is rather long, sitting at 12 seconds and as stated above, cannot recharge while Kuro is channeling. Another downside is that this skill will cancel early if the target dies before she finishes. It will not deal the additional damage and it will also not retarget to continue on a new enemy.
Because of this, Kuro is not well-suited to map clearing, and her preferred enemies are mainly Bosses or other high HP encounters.
Her Ultimate is the only AoE she possesses, but its value is not as highly regarded as others. Still it does provide additional damage based on her own Hashrate for allies attacking enemies within the zone. It can be useful in helping to quickly wiping out a Bosses summoned minions.
Kuro pairs well with Daiyan whom is able to give Kuro the ability to crit. If a crit/crit damage build is used along with Daiyan its capable of some disgusting damage. Daiyan has respectable AoE too, making up for Kuro's almost complete lack of it. A match made in heaven, really.
