Yeah, sorry about the last one - i confused myself, and now confused you too.
Here is the explonatiom: after i revived Cha, I emidiately rushed to lvl her up to 22. But upon defeating enemies she didn't gain XP and there was just text "Max Rank" or something like that.
What I thought was - "Cha is a low rank momstergirl, that's why i can't lvl her up above 17, which means that she doesn't have 4th and 5th forms. Aaaah, i get it now" - but i DIDN'T get it! I just didn't rank her up, thay's why her lvl was locked. But i did the thing, so now she's rank 5, in all her glory and might.
And i'm sorry, Mr NoseBecc, but... "The Golbins' sudden and impressive growth spurt-" growth... 'spurt'? Growth SPURT?! That's an understatement if i've ever heard one! That's not a 'spurt' that's a growth BOOM! A growth 'atomic explosion'!! How is Cha planning to walk after that?! Her bossom is heavier than her whole body!
