Ranma was introduced in this latest return of the collab and while I watched that anime when young, I'm not going to roll a lot for him/her as she's not "Aizen-tier".
Rank 50 free roll: Akane (1st copy)
I'm happy with this as she has a lower CD active to unlock orbs making it the same as a board randomiser active. She also has the 7 combo awakening which is interesting and synergise well with the new UVO Hathor although you need 2 subs with 2 SBR... Definitely keeping this card.
