I am writing this to inform the producers that is making Season 4 for High School DxD to change back to the original styles (Mainly for Akeno and Rias Gremory) because changing up this late in the story seems bland and a slap to the fans face for their favorite characters.  I don't understand on why it was changed, knowing it was by a new studio. So if anything can be done to revert back to their old hairstyles (The lighting and vibrant colors are awesome if they were affected to the old style) that would be awesome. If anybody from the studio at Passione (Japanese Animation Studio) would be kindly to change it the Art or hairstyle back (Maybe the art to?), it would be greatly appreciated. Ichiei Ishibumi is the creator of the series so if anything would be awesome to get contact with him. But it comes with the whole new design look and it bothers me how its been changed to more "Kawai" look.
