{{Nihongo|'''Mana'''|魔力|Maryoku|lit. ''Magical Power''}} is the energy used to perform [[magic]].

==Principles==
Mana is a form of energy that exists in all forms of life; [[Magician|magicians]] however, are capable of harnessing it for practical purposes. A method for producing mana is to convert the {{Nihongo|'''life force'''|生命力|Seimeiryoku|lit. (one's) life force}} of a living organism into it. This conversion is treated as being similar to refining crude oil into other substances, which effectively enables its use for different reasons and in different ways. There are various schools of magic that use their own forms of mana for casting. Two notable examples of such schools are the [[Norse|Nordic]] and [[Shinto]] styles, and each requires particular 'kinds' of mana for casting that other styles might not use.<ref name="IndexV9">{{Qvl|Index|L|9}}</ref><!--Mana, as an energy generated through life force, is connected to [[blood]], as shown by Index. After being injured by [[Kanzaki Kaori]], Index's mana loss due to bleeding exceeded such a degree that [[Index Librorum Prohibitorum/Abilities#John's Pen|John's Pen]] mode activated for initiation a [[Healing Magic|healing]] ritual. After the ritual ended, Index's mana was replenished and her condition stabilized.--><!--Do not re-add Index V1 blood loss case, there are inaccuracies/inconsistencies which need to be assessed/addressed and multiple other related cases being assessed-->

There exists a form of mana that is generated by the earth; it is available for use by certain magicians and magical objects. Once used, it is visually represented by "leylines", which are used as a sign of the fact that the mana used had been generated by the earth itself. Mana can also be inserted into objects through the use of complex rituals. This results in the creation of new "[[Spiritual Item|magical items]]" that possess certain magical properties of their own. For example: at one opportunity, [[Index Librorum Prohibitorum|Index]] had referenced the ritual needed to add power to a holy cross.<ref name = IndexCh35>{{Qcl|Index|35}}</ref> Its to note that mana is incompatible with [[AIM (An Involuntary Movement)|AIM]] and it is because of this that injury occurs whenever an [[esper]] attempt to perform magic.<ref name="IndexEp17">{{Qal|Index|E|17}}</ref>

A consequence of a magician's training to develop and improve their magical performance, is the strength of their mana being greater than that of an average person. This interestingly allows a magician to detect other magicians in close range, which is useful for aiding them in their identification of other magicians.<ref name="IndexEp7">{{Qal|Index|E|7}}</ref>

Experts in the field of magic have hypothesised that since mana is convertable from the caster's life force, [[immortal]] beings should be able to produce an infinite supply of mana. This should thus allow them to produce an infinite amount of magical effects; effectively causing their magical capacity to be far greater than that of any ordinary magician. This is one of the many reasons as to why [[vampire]]{{TrackTag53|s}}s are thought to be invincible by many within the [[Magic Side]]. Many on the Magic Side, such as alchemists, have also sought the abilities of vampires for purposes, such as the completion of [[Ars Magna]].{{CiteH|OT2 Specific}}
