Minus Wave...? This was something Yukine couldn't understand. Things from other worlds well outside of the problems of little Hikarizaka. She looked down for a moment... then brought a trio of coins up.

"I have a spell that could help you get the knowledge and experience that you need for the days ahead of you," she slid all three coins to Goku, "you will have to put all three coins together as if they were a pyramid, and then set the card of the joker above them, and think of what you want for your future."

Yukine smiled, "this is a spell that ensures you will go through a great journey that will allow you to learn, and form friendships you will get to keep with you."
