WN/Ultimate Skill

An Ultimate Skill (究極能力) is the evolved form of Unique Skill and the final evolutionary stage of Skills in general.

Ultimate Skills「, Arutimetto Sukiru」are evolved skills that are nearly impossible to obtain. Any beings (human, demi-human, monster, or demon) can obtain them.

The specific requirements to obtain an Ultimate skill are quite vague. However, it seems that those of very high ability are able to develop them. The majority of Ultimate skill users are quite old (hundreds of years old). Although it is possible to quickly acquire an Ultimate Skill through becoming a True Demon King, this is not guaranteed. In order to acquire such a Skill, great willpower and control is needed. An ultimate skill strength is such that it must be defended against with another Ultimate Skill/Ultimate Gift.

A normal human's body can't handle the burdens of an ultimate skill's energy. Under normal circumstances, awakening is impossible. That's why the modified body of an "Otherworlder" or similar physiques needed. But, at the end of one's training people will "Evolve." Their race aside, there certainly is a change. In other words, from a human to a sage.

It is also possible to bestow skills close to Ultimate skills by one's master if he holds an Ultimate Skill by himself but in a much weaker form, known as Ultimate Gift.

In Chapter 190 of the web novel, as Rimuru pondered about the nature and existence of skills, unique skills, and ultimate skills, he explained how even if some (unique) skills can be grouped together because of their similarity, none are identical. He also explained that it's possible for skills with the same name to have different performances and rules.

As such, the name of a unique skill (and also an ultimate skill) can be thought to be a 'label' given to a 'container' that has the probabilities of obtaining numerous effects. This can be thought of as a game skill capable of exhibiting 10 effects total, but the player has only 6 while the other 4 are grayed out or invisible. An example of this would be Rimuru's Ultimate Skill Uriel and Chloe's Ultimate Skill Sariel both evolving from and having the properties of Infinite Prison.

Another example would be Carrera's Abaddon that added Sandalphon's effect "Divine Edge" to itself, meaning that Extinction King Abaddon already had the "aptitude" for Divine Edge but simply didn't obtain/unlock it until that time.

Official Skill Series
Currently, the only officially used terms for the types of Ultimate Skills are the Sin Series and Virtue Series.

Sin Skills and Virtue Skills
The Sin and Virtue Series' Ultimate Skills are based on the and the. They are regarded as high-quality Ultimate Skills. The strongest individuals in the story either possess, desire, or at the very least have their attention drawn by one or more skills in these two series.

As such it may be no surprise that the Sin Series requires a unique process to obtain (this is not shown for the Virtue Series). First, a seed manifests in powerful individuals exemplifying the sin in question. Once rooted, if the sin is then nurtured by epitomizing it through one's thoughts and actions, it may blossom into the Ultimate Skill. At that point, any concurrently budding seeds of the same type in other users will vanish instantly. Like all Ultimate Skills, only one user at a time may be in possession.

These two series exist in opposition toward each other. For example, Justice King Michael rules over the Virtue Series, but if a user possesses equal or more Sin Series than Virtue Series skills, they can resist Justice King Michael's influence. There is no equivalent ruler of the Sin Series.

Speculatively speaking, the natures of virtue and sin may represent some racial affinity. Namely, in how angels lack the will and are predisposed to a ruler for guidance, while demons are limited by evolution, perhaps thematically represented by a seed growing before realizing full power. Certainly, there are no demons with a Virtue Series skill nor angels vice versa; in fact, the skills may reverse if the racial alignment changes, assuming Dino's case (explained below) can be applied to the Sin and Virtue Series. Two Ultimate Skills related to the above also exist: Sky King Lucifel used by the Seraphim Dino, which transformed into Fallen King Lucifel when Dino transformed into a Fallen. The first is not definitively explained, but the latter is a hybrid of Prideful King Lucifer and Wrathful King Satanael, hence their placement here.

Trivia

 * In the story, the characters pronounce Ultimate Skills using only the being they reference and not the entire names used in the wiki and translations. Meaning, it's "Ultimate Skill Beelzebuth" not "Ultimate Skill Gluttonous King Beelzebuth." This is due to the Japanese texts themselves. (See: and
