If these rolls are made out of guaranteed 5* gacha then you're very lucky. But you should do that guaranteed gacha roll and use the account that didnt get same 5* girl, cuz extra inventory space and skill up isnt very important in early game you know. The most of the guys here couldnt get a 5* girl from dat 50 gem roll, me included. As for alts i'd go with toad lily one because i hear ppl dont like convallaria much (her ability sucks), toad lily's ability is very useful for some maps.
