User blog:BMMS25/Which Character's/Characters' Stories Should I Focus On Next?

I'm doing/going to do stories formthe following characters : Ryoto "Ryo" Narukima and Mayumi "Mayu" Chidori (Villigas),Renard "Ren" Roarkus (Landias),Coya Mishira Shina and Hiroshi Roarkus (Planetis), Galaxia is mostly meant to just show how the characters ended up.But now I'm not sure if there's other characters who would need a story to for their past instead of adding a long flashback in one of the stories.
