He told you that all criminals sentenced to death can be freed if they get the elixir of life on the island. Right now, you were in Shogun Square with your hands tied in front. Your observer Tenza was standing next to you, after hearing all the criminals went to Shinsake Island, arriving at it Tenza decided to escape from the island by boat with you, after you saw huge monsters similar to gods.

Sitting on the boat, the observer diligently worked with the oars. So what you didn't know is that it's impossible to escape from the island..

Soon.. We'll escape and everything will be fine, Ha! Tenzo said, a little out of breath
