<h1>How much money do I have to spend before I get Kitasan Black as of 11/17/25?</h1>
A friend of mine recently recommended that I try out the gacha game that was all the rage in Japan Uma Musume.
It was popular enough to generate about a billion dollars in revenue in 2021 alone.
It's literally about gambling to get anime horse girls.
One of the best horse girls Kitasan Black is notoriously difficult to obtain because she is SSR rare (whatever that means) and the chance to pull her is only 0.04% which translates to an expected value of 2500 (1/0.0004) pulls to get her once.
Considering each pull costs 300 yen (about $2.25), you would expect to spend about 750,000 yen (about $5,625) to get Kitasan Black in Japan.
The game was released in the US recently, and the rates are the similar.
However, the game offers various discounts and bonuses for buying in bulk.
For example, buying 10 pulls at once gives you a almost guaranteed SR (not SSR) character on the tenth pull at 97% and a SSR at 3%.
In the US 5000 karats costs $69.99 and considering that 10 bulk pulls cost 1500 karats, that means 10 pulls cost about $21.
Therefore, the expected cost to get Kitasan Black in the US is about $11,250 if you do not choose to re-roll.
This is quite a bit more expensive than in Japan, but I that's to be expected given the different pricing strategies in different markets.
Overall, if you're thinking about trying to get Kitasan Black, be prepared to spend a significant amount of money.
Let's build a simple simulation to see how much it would cost on average to get her.
Good luck!
