Just wanted to show that is possible to get it with a visual proof, and not only that, but that is possible to get it for free with a bit of patience.

I play the game since january 2017, server 302, and since i always played azure fang i didn't rush to get him since for her both kirin and koh didn't appear as mandatory summons to get as soon as possible (at least for the teams i ran so far), so I chose to go for the waiting policy and I got him today, after 16-17 months of playing.

I'm not sure if they were 2000 rolls, seems to me were way less.

For the first 5-6 months i didn't take fully advantage of the rebates (just did the 50 tier) and in the following months i mostly reached the 80 tier in the rebate, just twice the 100.

P.S. the waiting policy paid off pretty well too. I just bought the 40 fragments i missed of kirin and I gained around 3300 power by using the saved up summon points and runes and by leveling both of them up to the 5th circle (with around 4500 unbound runes i saved up for them in the meanwhile).
