An interesting tidbit I picked up on Baidu:

Spoiler for Ryuumonbuchi's performance in the previous year's national championships:

According to the mangaka, they were crushed by Jindai, supposely another monster listed by Fujita.

This will be explored further in future "extra chapters".

Does the mangaka has a blog? Apparently from there, it seems it does. What's the link?
