Introduction
Tensei Shitara Slime Datta Ken, also known as That Time I Got Reincarnated as a Slime is a Light Novel series written by Fuse. The series started back in 2013 in form of a Web Novel and later received a Light Novel publication which was further adapted into both Manga as well as Anime due to insane popularity in east. When it comes to hax and abilities, TSSDK is one of the best eastern fictions, where even low tiers are capable of Atomization, Soul destruction, Light-speed attacks and so on. The following blog will elaborate upon the several terminologies and unique concepts involved in the verse.
Cosmology
Ultimate Skills
- Ultimate Skills are the evolved versions of the "Unique Skills". The ability of a Unique Skill is one of a kind. Once it evolves into an Ultimate Skill, the difference of power becomes extremely big. The possessors of Ultimate Skills comes to understand the laws of the world. Eventually making them superior when it comes to utilizing magic. A Unique Skill user can never defeat an Ultimate Skill user.
“ | I’ve possessed a Unique Skill since the time I came to this world. Basically, it is said that only hero class individuals possess Unique Skills. However, the ability is varied as it is called unique; that is, one of a kind. As it is unique, there is a great difference in the strength of the ability, if it becomes an Ultimate Skill, then there would be differences of power, like heaven and earth. The people who acquire an Ultimate Skill will come to understand the laws of the world. Therefore, they are existences that are superior in utilizing magic. Since it is more superior than Unique Skills, I thought that the only thing that could oppose an Ultimate Skill, was another Ultimate Skill | ” |
– Chapter 190 |
- Ultimate Skills' possessors are the existences which are released from the Law of the World.
“ | The existence released from the Law of the World, people who posses Ultimate Skills.
Ruminas in front of her. Rimuru that Chloe loves. And she realized that Rimuru’s existence was necessary to rewrite destiny. Perhaps, because Rimuru obtained an Ultimate Skill, he slipped out from the Law of the World, and so he might be the reason of the current miracle? No, more than that. |
” |
– Chapter 125 |
- When two Ultimate skill wielders are fighting, the only key to obtain the victory is to understand the opponent’s ability first.
“ | The experience of defeat had made Leon strong.
After all, in a battle between Ultimate skill wielders, the key to victory is to understand the opponent’s ability first. If a person couldn’t comprehend what had happened, then his defeat is inevitable. For Leon, Guy was a person capable of overwhelming others so. Then, for a person without an ultimate skill, prevailing against those with one is impossible. Going as far as preparing a number of thing to prevent confrontation. |

– Chapter 133 |
- One of the primary benefits of possessing an Ultimate Skill is that it's user is not affected by lower abilities as every rule of the world is ultimately reduced to this unique level. Making them almost immune to any form of magic-highest or not unless said magic is related to another Ultimate Skill because only an Ultimate Skill can counter another Ultimate Skill. Furthermore, Ultimate Skills do not require any incantation due to which merely wishing for something can produce required results. Another major benefit of an Ultimate Skill is that the Spiritual Attacks are completely meaningless because a soul weak enough to be affected by such attack could never acquire an Ultimate Skill, essentially making every Ultimate Skill user auto-resistant to Soul Manipulation.
“ | Those who possess an ultimate skill are not affected by lower abilities.
Every rule of the world is ultimately reduced to this unique level. In other words, they will not be affected by any form of magic–highest or not. And since ultimate skills do not require an incantation, merely wishing for something can produce results. A series of attacks of certain affinity could have an effect, though. Spiritual Attacks, however, are completely meaningless. A soul weak enough to be affected by such an attack could never acquire an ultimate skill. So to counter an ultimate skill you need another ultimate skill. Therefore, Clayman can do nothing to Milim. |

– Chapter 81 |
- It's almost impossible to steal an Ultimate Skill from someone as the Ultimate Skill is born deep from one's soul and is etched into the Nucleic Heart (core of the soul) unlike normal skills which are beat into the body or Unique Skills which are engraved into the outer crust of the soul.
“ | Ordinarily, actually stealing an Ultimate Skill from its owner was impossible.
For that Skill would be born from oneself, deep from one’s soul, and would be etched into their Nucleic Heart. The Ultimate Skill was truly personal, as opposed to Normal Skills beat into the body, or Unique Skills engraved into the outer crust of the soul |

– Chapter 185 |
- Due to Ultimate Skill being at a higher rank of magic, magic doesn't affect a person having an Ultimate Skill as it ends up getting nullified. Although, this mainly applies to only offensive magic. Hence, providing magical support to an ally is possible.
“ | Magic doesn’t affect a person who possesses a Ultimate Skill.
In a sense, this was the natural result because Ultimate Skills are of a higher rank of magic. But, it’s effective even if it only gives an indirect effect rather than a direct one. In other words, weakening magic and the like wouldn’t work, but giving support to an ally vanguard was effective> |

True Dragons
- True Dragons are one of the strongest beings of the verse. They are just a mass of magic essences (Spiritual life-forms) due to which they aren't bound by a life span or flesh. They are also immortal as long as they have will.
“ | Then, as for why I cannot reproduce… there is simply no need.
As I’m a “Perfect Individual”, one of the four ever existed “True Dragons”. “Storm Dragon Veldora!” is I! I am bound by neither life span nor flesh! A mass of magic essences, and as long as I have Will I’m immortal !!! |
” |
– Chapter 3 |
- The physical bodies of True Dragons are only a response to the belief of the surroundings.
“ | (That’s. Then, Should I look for something for the preparation?)
(Hmm. Actually, I don’t need a core… the secret you ask? Because I'm a “Perfect Individual”. A special being. As I’m a spiritual life-form, I have no fixation to physical body. This physical body was only a response to the belief of the surroundings.) |
” |
– Chapter 4 |
- True Dragons have Resurrection as they don't disappear even after death and simply revives somewhere in the world with the same will.
“ | I didn’t really mean it when I said that Gaia can become a real “True Dragon”……
Ehh, it can’t be!? At the same time that I thought of the possibility, the “Dragon Core” conspicuously glowed and flickered at the center of the tetrahedron. 《You’re aware that a True Dragon won’t really disappear, right? The same also applies to Zero who had become the insane, destructive “Berserk Evil Dragon”. He will revive again somewhere in the world and will just try to accomplish his mission as the “Berserk Evil Dragon” that was given to him by Velda. |
” |
– Chapter 233 |
- True Dragons are Intangible.
“ | When she asked, they responded that『Dragon Veldora is a monster and is also not a monster』.
A dragon is actually a holy spirit and is thus a ball of energy. Therefore they were nearly intangible beings. And further, they added. |
” |
– Chapter 87 |
Angels and Demons
- The Spirits of Light and Dark were born at the same time. Angel's Egg was laid by receiving the blessing of Light and similarly, Demon's Seed was sowed by receiving the wave of Darkness. Later when the Spirit of Time was born, the Angel's Egg hatched and the Demon's Seed budded. Thus in this way, Angel and Demon were born as a Conceptual Existence (Abstract Existence). Also being entirely Non-Corporeal due to no physical body, just a pure energy.
“ | To begin with, what kind of race is Demon Race?
In the ancient past, during the time when the Spirits of Light and Dark were born, receiving the blessing of light, the Angel’s Egg was laid, and receiving the wave of darkness the Demon’s Seed was sowed. At the same time when Spirit of Time was born, the egg hatched, and the seed budded. The two were born as a conceptual existence with a pure energy body without a physical body. That was the origin of Angels and Demons. The mysterious thing was that the Angels and Demons that were born at the same time were on bad terms. When they meet, fighting is unavoidable, long fights were repeatedly fought. |
” |
– Chapter 114 |
- Demons and Angels are existences like spirits.
Demons are specialized in the demonic attribute due to receiving power from the spirit of Darkness and Angels are specialized in the holy attribute due to receiving power from the spirit of Light.
“ | I was inside such world.
I seemed to be a Lesser Demon. Demons are an existence like spirits or angels. It seemed to be an existence that received power receives from the spirit of Darkness, and specialized in the demonic attribute. Similarly, the Angel specialized in the holy attribute of the spirit of Light, the exception to this seemed to be called a Spirit. To me, it was an unimportant story. |
” |
– Chapter 143.5 |
- Demons are capable of mesmerizing the targets by manipulating their minds as they likes by using their Temptation Skill.
“ | Because they feared me, they seem to have accepted it easily.『Temptation』, that is.」
Arnaud suddenly realized. There was a characteristic of monsters that were Demon-kin called the Temptation skill. To mesmerize the target. An ability that can manipulate someone’s mind as it likes. But, he’d never heard of a Demon that had the ability to mesmerize a Holy Knight. To save someone under this mesmerization you either have to defeat the demon who is manipulating them… or kill the person. To sum it up, the only thing that can be done now is to evade his companions attacks and defeat Diablo. If not, the only option left was to kill his comrades. He can’t go easy on the Holy Knights. Even subconscious, these guys were pragmatic. Someone who is mesmerized moves their body subconsciously. This was too much… their awareness was cursed through temptation. |
” |
– Chapter 90 |
- Even if a Demon's body is destroyed, it can revive himself via self-regeneration due to being a spiritual life form.
“ | The powerless ones had long fled, and those with strength had banded together to fight it head on.
But for that Demon, the grief of the weak and worthless could not be heard. That Demon completely destroyed its opponents, and continued to trample them calmly. Demons were a spiritual life form. Therefore, even if their bodies were destroyed, they would revive themselves through self-regeneration over time. Maybe knowing this, that Demon didn’t restrain itself and did not give mercy to those who came. That Demon was the avatar of dreadful violence. 「Kufufufu. There was no chance for my defeat, even if all of you small fries gather like this. |

Demon Lords
"Demon Lord" is a title given to the individuals by the "Voice of the World" (System created by the Veldanava) when they have evolved after fulfilling the requirements.
- The primary requirement is to obtain "Demon Lord's Seed" which is theoretically obtained after reaching the Demon Lord Class. A Demon Lord class being has an EP: 200,000 ~ 400,000. After evolving into a Demon Lord, the EP reaches 1,000,000+
“ | A normal demon lord class being has [EP:200,000〜400,000], and that's the lowest to the highest.
Similarly, a demon noble is [EP:200,000〜400,000] too and that is distinguished by the baron to the duke classes. Certainly, Leon-sama's followers have evolved and attained power, but they sit at the viscount class of [EP: below 250,000] at most. Kazaream-sama's fellow brethren too, with the exception of Laplace, are at the higher end of the demon lord class at [EP: below 400,000]. Neither are even remotely close, to be called beings that have power surpassing demon lords. The demon lords of the current Octagram, with the exception of one person, are all of the Million class at [EP:1,000,000〜]. |
” |
– Chapter 211 |
- The secondary requirement is to obtain at least 10,000 souls by sacrificing (killing) the equivalent number of human beings in order to make the "Demon Lord's Seed" sprout
“ | Whether it’s possible for me to become a Demon Lord, however...
((Solution. Master has already fulfilled the conditions for Demon Lord’s Seed. To fulfill the condition for evolving into the Demon Lord (for Seed to sprouts), it is necessary to sacrifice 10.000 Human beings (Souls).)) So, is it only that? So easy. Demon Lord? To become it. So easy. I only need to dispose 10.000 trashes, what an easy work. If it’s still not enough, I’ll just need to dispose more. |
” |
– Chapter 68 |
Once both of these requirements are fulfilled, the individual would be evolved into a Demon Lord.
- The skills of being undergoing the Demon Lord evolution also evolves. Demon Lord also acquires "Demon Lord's Haki" that is used to extremely intimidate the others.
“ | I declared exaggeratedly while not permitting them to raise any objection.
At the same time, I erased my presence while at the same time released the entire of 『Demon Lord’s Haki』 with the intent to slightly intimidating them. Perceiving such presence, the Gozu and Mezu fall prostrating. They begin to trembling and shaking, there wasn’t the slightest hint of the insolent attitude that they had earlier. Eh? Should I emitted『Demon Lord’s Haki』from the beginning....... No, there’s no need to be excessive. Besides, I’m fairly certain it was more effective if it was emitted at the right time. |
