Waifu Gatcha

You mortal. Play the demonic game of gatcha, the favorite game of the demoness Lilith. The wheel will spin, you might get a waifu, but it is not guarenteed. Of course, you can reroll, but the price is giving up who or what has been rolled. When will you stop? Will you stop? After all, this might just be the chance to win the gatcha.
