Sakura&that wolf

Wel we all know one of them as Sakura...but the wolf at her side is unkown..here's a little backstory to him...she only see's him in her dreams, well more like nightmares of that dreadful night..so he has some connection to what happened that night....what i can't decide on is whether to make a story for this or try to make a comic...I'm so confused!!!!><
