He went on a rampage, destroying towns with his fiery wrath.
Few hours later, at sundown, he found a girl walking home alone. He attacks her. But, suddenly, he was struck by a similar-looking boy. The boy started to feel strange and knelt down. Demon Mathew attacks! The boy blocks the hit while he was growing butterfly wings, attenae(?), and a butterfly tail. The butterfly boy gave Demon Mathew some powerful pulses from his palms. The Demon gave in. Mathew's demon parts shrank away, only leaving the marks under his eyes. The same happened to the butterfly boy's parts.
"Where... Am I?" asks Mathew.
"You're almost home..." Says the boy. The boy picks Mathew up and carries him home. Along the way, the boy says, "I am Dan Yuuki... Your brother. Remember?"
"...No" replys Mathew in a weak tone.
"You defended me from those bandits long ago. In return, I saved you from your evil form."
Mathew got teary. He closed his eyes and said, "Thank you... Brother."

Author's notes:
I know that the story was a little hasty, but this is My story that I made in comic form at school. The hastyness was caused by a short time to work on this. However, despise from this, the comic was featured at my local art show. Hopefully, I ca find the time to work on the pages some more and post the comic on dA. I hope you liked it as much as my teacher did.
