Ringo - Rainy dream

リンゴ ~ 雨天 の 夢

This is Ringo, he can travel to other people's dreams with the help of his "cloud". One of the first dreams he traveled to was Koneko's dream, there he met her and her ghost "partner", since then he thinks this cloud thing is also a ghost, but it's actually a "dream object", a being or object created by the imagination of a dreamer and that only exists in "dream worlds". Besides letting Ringo travel to other's dreams the cloud can also change to any form just keeping the cloud appearance

In this pic he is in a kind of rainy and dark dream, his cloud turned into a giant leaf umbrella. The dream being dark and rainy does not necessary means it is a nightmare, it can be just a dream of a person that likes rain a lot, like me or Lurils (character) XD
