If your looking to find daki you can do several things, first way is to increase your fame to 30 and then encounter her when you hunt for demons, the other way is to unlock her inthe cheat menu(what I did), there could be other ways that I'm not aware of but that's all I k kW for now.
Ps when you unlock daki you cand do her right away, I stead you unlock daki village where you have to build her love/trust like tho others
Ps ps I'm just a guy who plays the game alot so I don't know anything too well
Ps ps ps this is the longest response I have ever wrote
