Where does Rosa come from? Is she a premium character or is there a quest line somewhere for her?
Premium Cash Paytardo Character
Kay, just a small piece of advice: if you are one of those people that gets mad when other people call you paytard, maybe you should not use the term yourself and maybe it will just die out.
Other premium characters released by T3Fun include, but may not be limited to:
Queen of Pioneering Grandies/Granma whatever
Rosa Blanca (the one you were asking about)
Some characters were released in cash shop promotions before their quests were fixed:
Kano (? I seem to remember her being in a box)
Veil (? I can't remember if he was in a box or not)
