Uroboros: Ouroboros is a snake or dragon that eats its own tail. It is a symbol of eternal periodic reproduction. To put it simply, he doesn't die.
Snakes do various things, but they are similar, so it became Dragon to go like ZOCARO.
The expression is dignified and strong, and it is really ZOCALO's workmanship that cares about the expression depiction of scales and does not cut out until the back as usual.
