Name

Name (名前) is a term that refers to the "name" of an individual, or to be more precise, the name inscribed onto their 'soul'. Individuals who have a name are referred to as Named (名持ち) while those who don't are called Nameless (名無し). Named beings typically have much stronger wills as well as more diverse and complex emotions compared to a nameless being of the same age.

Naming
Naming (名付け) refers to the act of an individual receiving a name. There are three known methods for this process.

Equal Naming
Equal Naming is an act of naming that establishes an equal relationship between the namer and the named. This type of naming either consumes no energy to perform or costs so little that it's considered "safe" and the power received in return can be considered minimal. Examples of this are parents naming their children or Veldora naming Rimuru Tempest.

Master-Subordinate Naming
Master-Subordinate naming is a type of naming that establishes the named as being subordinate to the namer. This act consumes an amount of energy – Magicules if the namer is a Monster and Majin or Life Force (生命力) if the namer is Human or Demi-Human – proportionate to the strength of the being receiving the name. If the namer names someone too strong or names too many people without a long enough recovery time, there is a high chance that the energy expended in the process of naming will never fully recover. The benefit to this rather risky process is the power that the named individual receives. Someone named in this way forms a powerful soul bond with the namer, possibly even inheriting some of their abilities, and in the case of monsters and certain regressed demi-humans, they can even evolve.

Additionally, Rimuru developed a method that consumed the magicules in the surrounding environment in order to perform naming. This method obliterates the risk of naming to zero but, in return, the soul connection between the namer and named is significantly weaker than normal. Examples of this can be seen when Rimuru names 150,000 Orcs using the magicules still surrounding their body from the effects of Starved, and when Rimuru named the Black Numbers using the magicules contained within the culture pods that stored their bodies.

Named by the Masses
On extremely rare occasions an individual can receive a name through the collective belief of a large amount of people. Individuals named in this way receive all of the self-image and power enhancing properties of a name but without the need of ever forming a close bond with another person. Examples of this type of naming can be seen with Guy Crimson and Orthos.
