Courtesy of Arcadia themselves. The footage is Shiro vs Gosho and Kyabetsu vs Iyo. You’ll have to wait for the magazine release to see Shiro vs Kyabetsu for the deciding match. After that there’s 5R footage that no one cares about except for me and 5 other people.
Edit: I should mention for those who will UNDOUBTABLY BITCH, do you really expect them to put the entire match online. It’s a preview clip, so deal with it
