As a Day 1 Brown Dust 2 player, it is nice to see the New Collab bring new player. But has to point out the 100 pulls only guarantee Random 5* if you didn't get any 5* within 100 pulls. 200 pulls only Guarantee 5* you want.
I am loving the game so I am grateful for the SK collab because I never would have known about. Thanks for clearing that up since I am new to the game so I am still learning a lot of things about the game. So the extra knowledge is appreciated.
I think you kinda missed the biggest part of the collab lol, there's a whole story cartridge for it. Click Knight of Blood in the bottom right and then scroll to the bottom, you can get the Senran pack from "Events". For Fiend Hunt, make sure Hikage and Yomi hit the tile with "WEAK" on it for lots more damage.
