She can reduce enemy eva at night, which helps for some specific weird shit, but it isn't likely to come up.

Chinese Makarov clone. Similar job to SPP-1, but less boosting your side's acc and more on lowering the enemy's evade. With fairies now existing she's kinda useless.

+90% Acc Buff aura at 5-links. Also has a +damage up but that's just icing on the weird, underwater-themed cake. With NV equipment, allows you to completely destroy scouts in night battles if you're actually desperate for that. Normally not a buff I recommend, but she actually gives a lot of it so if you're wanting an actual acc buffer, she'll be 1 of the ones you want. Not as important anymore since there will be other sources of acc boost, but... sometimes you might want something?
