Rimuru

Human
Rimuru's facial features in human form are almost identical to those of
Shizu's long silver hair and deep golden eyes exude an ethereal, divine beauty that sets them both apart. Rimuru can also sometimes be seen wearing a Shizu mask or dragon wings.Personality
Rimuru is an eccentric and childish person by nature, but this should not be mistaken for immaturity and naivety. On the surface, Rimuru constantly analyzes, plans, and weighs the pros and cons of his actions, choosing the smart move in the long term over more rash and emotional decisions. Contrary to his reserved and calculating demeanor, Rimuru is ruthless when it comes to dealing with people who cause them genuine rage. They will resort to brutal torture and murder without even blinking an eyelid if they can get away with it, and they use more subtle methods such as intimidation and blackmail when the cards are in hand.
The Rimuru are also very concerned about their personal image, posting lies on official accounts, [3]
[4] erasing memories, [5] and creating fake historical documents to make them appear to be kinder and more benevolent people than they actually are. [6]
Despite Rimuru's often selfish and nefarious tendencies, they care deeply for their subordinates, viewing them as something like family or a set of children. And thanks to the memories of Satoru Mikami and Shizu, Rimuru has access to a reliable set of human ethics to fall back on when their more brutal monster self isn't up to the task.
Rimuru's goal in life is to create a comfortable world where they can relax and lazily enjoy entertainment similar in quality to that found on Earth.
