Durrem > You have some nice girls in there to choose from... haah the amount of Manyus... I am so jelly of ya !
Anyway you have two universally great girls in there: Appricot and Tritonia.
Both have skill act, and both come with the very rare, and super precious Barrier skill.
Appricot is slightly better then Trit (if Trit had better % on her "per type" buff she would be amazing, but as it is, the actual value is less than some bacic buff types other girls come with, without that stupid gimmick. 9% would be amazing, and 10% would be insane, but ah well... hope they buff her as I want to pick her up as well), and both of them are of great value in any type of team > but work best for high offensive teams like Critical or Boss Killers.
The reason being > sure you loose a bit of damage from swapping of the DMG girls for them, but the fact that because of the Barrier your team cane survive 1 round with the Super OP bosses who one shot anything or the ones who go First and twice, which double your damage even with the loss of one damage girl. After all its better to be able to fight in 2 turns and deal slightly less damage each, but more in total, than deal slightly more damage but fighting only once.
So yeah,
Apricot or Tritonia is who I would go with.
