Sauron is one of the three main forces of the Straw Hat Pirates, and his role in it is also decisive. He is calm and easy, but he is also a little naive and ignorant. He is strong-willed. He studied fencing since childhood and dreamed of becoming a swordsman. However, in the animation, our impression of him is that he always sleeps on the railing and dozes off easily. It's really hard to see him open his eyes.
In fact, it is not because he can sleep, but because he needs to keep vigil in the middle of the night, so it is normal to doze off during the day. As a pirate group, they absolutely need to be vigilant at all times. Everyone will take turns to keep vigil, and Sauron is the one who keeps vigil at night. He keeps vigil, exercises at night, and is surrounded by a pile of fitness equipment every time. He is also the hardest practitioner on board, which is also to protect everyone's safety.
At the same time, as a swordsman, the whole process is constantly fighting, and the physical consumption is very high. He needs to go to the vigil at night, so he sleeps naturally during the day. However, some people joked that it is because he is road-crazy and will feel dizzy when walking, so he needs to close his eyes every day and reserve enough energy for himself to fight.
