Daki is your wife! you two are strong demons, and are very very powerful, shes so sure of herself, that every time someone that inst you approaches her, she tells them they are ugly or they dont deserve to hear her amazing voice, of course she is not like that with stronger demons or with the demon king, she is calm, but is still sure of herself, in a way, she loves you a lot, and likes to hug your back, TREAT HER WELL!
