If you're looking to get a pure family off of Hotteatchi, then you can't. You can only get a pure family off of Mametchi, Memetchi, Kuchipatchi, and Violetchi.
If you want to mate it via Dating Show, then you can just pick any random partner for it. You'll then get a Blended Family.
Yeah, MnMztama495 is right. Maybe you can try again next generation. And remember, in order to get a pure family, you have to mate the right 2 characters and have 100% bonding.
