Hayato took in a deep breath before sprinting towards the demons. "Moon Breathing!" Purple energy trailed his sword. He leaped up and swung his Moon Breathing blade down at Y/n.

Y/n turn around he cracked a smile as flames burst around him. "Haha! Still kicking? And looks like you've been doing your readings! Perhaps I'll get some fun out of you after all!"
