I have a total of 27 girls, of them, Hikea, Pelagie and Clarisse are still at 2 stars, Samane is at 1 star, and now Agate and Abrael have "sprouted" 2 new stars each. (Red battler and Ankyo have been raised to 5 today, finally)
Abrael needs 15400 affection to raise to 4 stars, and Agate needs 6300. mathematics say that means that I need to raise 6.421.800 + 2.627.100 = 9.048.900 only in affection items to raise them to the next star. Isn't it getting a bit extreme?
P.S: for those who don't know, each affection point costs 417 "dollars" (common game money, not real dollars)
