Ryo Gate Skip
By using KTs you can jump over the gate towards North Ryoshima Coast. This allows you to skip going to Himiko to get the key. During the run to Ankuko Temple after Dragon Palace the gate will open normally. The same goes for going towards Oni Island.
How to do
Simply run up towards the gate, do two KTs and end on a dash to get over the invisible floor above the gate, landing in the loading zone.
