Himiko's Palace Escape

Explanation

Normally, to leave the courtyard of Himiko's Palace, one must pass by the guards at the front entrance. During the Evil Rao chase sequence, Issun will prevent Ammy from leaving this way, making it seemingly impossible to leave the palace. However, we can clear the high invisible walls surrounding the palace by jumping onto the slippery collision of the roofs above the treasure rooms and the paths toward them. From there, one can jump or perform a Sliding Ground Tackle to jump over the walls.

This is used in NG All Brushes and Top Dog to more quickly reach the Sei-an Aristocratic Mermaid Spring after talking to Queen Himiko as well as after obtaining Deluge. It saves roughly 8s compared to going through the guards. This is also done in NG+ AB to go to the Imperial Palace dungeon in the middle of the Evil Rao sequence.
