Rimuru Tempest (リムル゠テンペスト) is the protagonist of Tensei shitara Slime Datta Ken (That Time I Got Reincarnated as a Slime). Rimuru is a former salaryman turned blue slime when he is stabbed and killed trying to save his junior work colleague Tamura. Quickly gaining a multitude of skills while assuming a human form, he becomes the founder and King of The Jura Tempest Federation and he resides in Capital City Rimuru. He is also known as the "Tempest of the Great Jura Forest" due to the overwhelming impact he has on everything and everyone around him.
Rimuru acts like a mature adult trapped in his new slime body though he does have a youthful fun loving side to him at times as he says he will "always be a child at heart". He usually makes thoughtful decisions and is never rushed. He is kind-hearted, loving and has an exceptionally quirky personality with some beliefs and strange behaviours that others find hard to understand. Although he is quite easy-going and may appear to be laidback at first glance he constantly tries to stay out of trouble and he is an incredibly hard worker Rimuru used to be a white collar worker and his polite nature is hardwired into his DNA meaning that he has an impossible time rejecting someone if they plead him to help, leading to him often ending up with more work than one could handle on their own. Apparently it was a point of contention that his boss from his previous life used to bring up to him. Rimuru's most useful skill is his inner cunning and shrewd nature. Rimuru has survived against lots of enemies by defeating them with his quick wit and decision making. Rimuru is also incredibly diplomatic and will take any measures to avoid conflict.
The quickest way to upset Rimuru is to hurt those close to him. He might seem like a bit of a drama queen however in actuality these rare situations bring his big heart and loving, caring nature to the forefront. In contrast to this, he also has a very cold and unsympathetic side to him which is not shown as often in the anime adaptation. In the light novel especially Rimuru tends to be very suspicious of new visitors at first. Rimuru also has the tendency to become paranoid and also wary of those surrounding him if he feels like he is going to be betrayed or abandoned mentioning that he would quite easily be able to murder his followers if they decide to go against him but also reiterating that his subordinates are free to assassinate him if he should ever lose his mind.
What holds Rimuru back the most are his anxiety issues which cause him to doubt himself quite often. He is easy to persuade during diplomatic negotiations, often agreeing to deals that mean bad news for him. King Gazel repeatedly drums into Rimuru that he needs to change his humble and softspoken nature if he wants to be taken seriously as a leader. Rimuru's kindness and desire to be faithful to his old species doesn't bode well for his future, however he is willing to shoulder and take responsibility for any mistakes he makes along the way. Rimuru is always putting himself down and can be quite a doormat when it comes to enemies until he learns to have more respect for himself later on. His soft and kind nature allows him to be taken advantage of but it means that he is able to keep a cool head, so in some situations his unassuming manner is very useful. Dealing with being "monsterfied" was very difficult for him and it takes him a while to adapt to his new existence, as he grows used to his body after his monsterfication he becomes more detached from his old human self acting more like a monster with a human heart.
