I am Ranyudo as for, I am both, Ren and Wanyudo.
I am Ai's first companions and Ai's best friend. I am a mysterious boy, same age as Ai. I can change form as the Youtube Comment Box and Message center. I also take forms of anything where you will confirm your revenge, and also objects. I help Ai in making people feel bad in their hearts.
I am also very close friends with Hone Onna. Hone Onna and I investigate the cases to see if Ai should really ferry them to hell/get punished.
I am mostly pissy and grumpy to those damned people.
