u/Indignusy7

So i just pulled chisa by winning my 50/50 i was expecting to lose because i already won 4 times consecutively but i didn't expect to win on my last one pull.

I dont have any pulls left for her weapon, and dont have the standard broadblade weapon. What four star alternative should i use if i want her to be a support for my hiyuki? And is hiyuki lynae chisa better than monye?
