Short review:
This one shot was created by two people, the art from Obata, Takeshi (Death Note, Hikaru no Go, Bakuman), and the story from Morita, Masanori (Rookies). Which I thought was pretty cool and so I decided to read it. I don't know any words that can describe this one shot but it sure was a ride. The art was absolutely beautiful and the story was really a tragic of betrayal.
I don't know about you guys, but I really enjoyed reading this one shot. The characters in here weren't really revealed nor developed, but it had the potential of becoming a series. So overall, I gave it a 8/10.
