Rimuru Tempest Plot

Satoru Mikami is an ordinary 37-year-old corporate worker living in Tokyo. He is almost content with his monotonous life, despite the fact that he doesn't have a girlfriend. During a casual encounter with his colleague, an assailant pops out of nowhere and stabs him. While succumbing to his injuries, a mysterious voice echoes in his mind and recites a series of commands which he could not make sense of.

After regaining consciousness, Satoru discovers that he has been reincarnated as a Slime in an unfamiliar world. At the same time, he also acquires new-found skills, particularly the ability called "Predator," which allows him to devour anything and mimic its appearance and skills. He stumbles upon Veldora Tempest, a Catastrophe-level 'Storm Dragon', who was sealed for 300 years for reducing a town to ashes. Feeling sorry for him, Satoru befriends the dragon, promising to help him in destroying the seal. In return, Veldora bestows upon him the name Rimuru Tempest to grant him divine protection.

With his newfound powers and his wisdom, Rimuru gains the friendship and loyalty of the monsters inhabiting the Great Jura Forest, who accept him as their leader and together they found the nation of Tempest. As their new nation quickly grows in strength and influence, Rimuru and his subjects draw the attention of the nearby foreign powers, from monarchs and legendary heroes to demon lords, some seeking to become their allies, while others intend to just take advantage or destroy them completely for the sake of their plans.

Raphael, Lord of Wisdom

• Mind Accelerate - Lets user extend their thoughts by up to a million times.
• Analyze and Assess - Analyzes and assesses the target.
• Parallel Operation - Operates on any matter the user wishes to analyze, separating it from the regular thought process. Any process under Parallel Operation is affected by Mind Accelerate and therefore sped up by a million times.
• Cast Cancel - Annuls the casting period required when using Magic, etc.
• All of Creation - Allows the user to fully comprehend any non-concealed phenomenon as long as they have a certain amount of knowledge beforehand.
• Synthesize - Transforms two differing targets into a single object.
• Separate - Release the properties inherent to the target and make it into a separate object. (The original object may disappear if it has no physical form.)
• Skill Modification - Allows the user to modify or even evolve skills under the right circumstances.
• Future Attack Prediction - Allows the user to see from a series of outcomes which is going to happen. (The results that have been calculated have a 100% chance of occurring).

Beelzebuth, Lord of Gluttony (Evolved from Gluttony after sacrificing Merciless)

• Predation - Absorbs the target into the user's body. Chance of success is lowered if the target has a consciousness of any kind. "Predation" can be used on organic, inorganic and non-physical objects (e.g. spiritual life-forms like Spirits and Demons), as well as Skills, Magic, Arts and any projectile-type attacks of the aforementioned categories, as well as magicules themselves. Compared to its Unique Skill counterpart: "Gluttony", it has been improved and can now ignore space and time to consume anything in the user's perception.
• Stomach - Stores the predated target. It can also store materials created via Analysis. Items stored in the user's stomach are unaffected by time. Its space is roughly 10x that of Gluttony's.
• Mimicry - Allows Rimuru to reproduce the form and Skills of absorbed targets. Only available once the target has been fully Analyzed. Originally most intrinsic Skills gained from a predated species could only be used at full capacity by taking the form of said species, but Universal Shapeshift negates that issue.
• Isolation - Stores harmful effects that are incapable of being analyzed, neutralizing them and breaking them down into magicules.
• Rot - Inflicts "Rot" on the target, decomposing it if it is organic. Monster corpses partially absorbed in this manner will reward the user with part of the monster's skills. This effect is imbued by Predation.
• Soul Consume - The ability to seize the souls of anyone begging for their lives, seeking help from the user, retreating, or running away. Once the condition is met, the soul can be seized at any time afterward, from virtually any distance instantly. The user can be informed about any malicious thoughts by the target immediately. The souls of the recently killed can also be seized.
• Food Chain - Derived from "Receive" and "Provide". An ability that allows the user's subordinates to provide their strength to increase his own. He may also divert some of his strength down to them. "Food Chain" also grants him access to the skills of those connected to him.

Uriel, Lord of Vows

The combined state of all the abilities received from "Food Chain" after the Harvest Festival, using the space manipulating Unlimited Imprisonment as a base,

• Spatial Domination - The enhanced version of Spatial Manipulation that allows the user to, among other things, Teleport instantly with little to no delay, to a place the user has coordinates of as well as lock the local space around the user to prevent space from being manipulated.
• Absolute Defense - Provides absolute defense with a multilayer barrier and the severing of space between each layer.
• Unlimited Imprisonment - Traps the target in an infinitely complex number of spatial dimensions.
• Law Manipulation - Black Fire and Thunder. Total magical control. Total control of the properties of heat and inertia. The ability to freely store and remove heat from the Stomach. It is also capable of altering reality. Rimuru's version of this ability allows him to use the skills he obtained via Food Chain.
•  

Veldora, Lord of Storms (Gained after Beelzebuth ate Veldora's remains inside the stomach)

• Summon Storm Dragon: - An ability that calls forth Veldora in his dragon form.
• Restore Storm Dragon - An ability that copies Veldora's memories into his own mind. In other words, if Veldora dies for some reason, he can replace him or, to put it another way, the “real” Veldora would reside within his own soul.
• Storm Magic - Allows the user to access Storm Magic.

Rimuru Quotes

If it looks like I stand no chance I’ll run away and think up a new plan, but otherwise, I should see how strong it is with my own eyes, right?

Humans live with groups. If you mess with them, they could retaliate in a big way. And if they came after us in earnest, I doubt we could handle them. Besides, getting along benefits us in lots of ways, anyway.”

It's why this power exists. Ideals without power to back them up are just idle daydreams and power without ideals is just empty. I'm not interested in seeking pure power for power’s sake with no other particular goals in mind.

Take the hard drive out of my computer at home… Put it in the bath… And make sure it’s completely wiped

I underestimated you, but not as much as you underestimated me.
