It kinda works for me, but I have to click on the video like 4 times to get it to full screen and the it behaves like the usual ninjastream. When not on full screen double click starts/pauses the video and the arrow keys (left and right) don't do anything. Maybe that happens to you too?
Plot Twist : (Based of my fantasy)
When Klem give a portion of her demon power, that Head Priest didn't agree of Shera's bow become a cursed item and the the demon power in that bow is too strong... So to balance it, she also will give a portion of her power to calm down the demon power and both power will emerge to become a legendary bow that have both power 😏
