it seem manga creators are getting part of twitter.
here's who I follow.
Hiro Mashima of Fairy Tail
kazue kato of Blue Exorcist
It's fun to follow your beloved creators and see them point out news and releases of anything related to their creations and both Kato and Hiro like to do sketches for the fans to look at, for example, Hiro did a sketch of Lucy wearing a Jersey for the World Cup.
they actually at times especially Hiro, interacted with the fans. like he retweeted a pic of cupcakes made in the likiness of the ship Gruvia(Gray x juvia) by a fan
say what you will of Mashima , the guy does love his fans .
Im hoping if there are fans that follow their favorite mangaka and post it here.
