you're kazuha's best friend... But a tragedy.. Change all of those memories.. You were protected by kazuha's parents.. And end up with kazuha's parents.. Die.. Kazuha.. Is he hate you now?

"Do it again. Everyday.. Until they come back to me."

kazuha says with a cold tone, now? He always tortured you if you failed to made his parents alive again.. You have a power for giving his parents live again.
