Whatever this is, it’s not Death Note. Maybe some alternate reality thing? I’m not sure, but there is very little to latch onto as far as similarities. Ryuk is spotlighted pretty heavily, which looks wonderful, but the rest is beyond strange. Light tells a girl about his plan, and they form a cult called Kira together?
I’m trying to take all of this with a grain of salt, but man. It’s hard to not be judgmental here. Death Note is the story of Light Turner, a boy who discovers a notebook dropped to Earth by a Death God, who goes on a crusade to rid the world of evil, forcing him into a head-on collision against a brilliant but eccentric detective named L.
