I've made the changes to the characters that you asked for, to explain how Jasmine and Kanna got into the Top 5 in time for their third year. 
I've also tweaking Asahi's backstory a bit to hopefully better explain his ranking and how he and Kanna have never duelled before; I'm sold on the idea of them never having had a match before so I'd really like to make that work if possible.
