I fully agree with PraiseLuka. What you could be mad at though, is the ammount of coins you received for duplicated kirin. 4k looks like a joke, considering his frags cost 6.7 times more than any other rare summon. When you pull a dupe rare, you get coin equivalent of 11 his frags, with kirin you got 1,3 frag value. I'd asume you'd get at least 10-20k coins. For me, thats the reason to get mad.
