Take Over: Spirit Soul

Take Over: Spirit Soul ( 接収・諸召喚獣(テイク・オーバー・スピリット・ソウル) , Teiku Ōbā: Supiritto Sōru lit. Confiscation: Various Summon Beasts) is a subspecies of Take Over: Animal Soul that deals with a peculiar category of absorbable targets, in this case, anything that can be defined as a "summon beast" (召喚獣, Shōkanjū), ranging from Celestial Spirits, Elemenian Spirits, and possibly many more; essentially, as long as another magician can summon them, the user is capable of utilizing Take Over on them and taking their souls.

As one may have already guessed, Take Over: Spirit Soul is an Ancient Spell (古代魔法 (エンシェント・スペル), Enshento Superu lit. Magic from Ancient Times), a power that has long been forgotten to the annals of time; the reason for which is because of the dangers of using the magic the way it is intended.

Take Over: Spirit Soul appears in Daybreak S1 and S3 under the command of infamous wanted criminal Altrouge.

Description
Take Over: Spirit Soul is a Take Over Soul that is considered long-forgotten to the sands of time, in addition to being classified as a forbidden magic due to its power. In order to initiate Take Over, the user must firstly defeat a living non-human being, and then grab ahold of it, surging their Magical Aura into the creature, using their magical energy to enter the beast's Magic Origin and overwhelm it, quickly replacing the target's magical energy with their own, resulting in the loss of magical power causing the body to break down into eternano particles and becoming absorbed into the user's own Magic Origin. As befitting of the name of the magic, Take Over: Spirit Soul only works on beasts that can be defined as a "summon spirit" or "summon beast"; as Spirit Soul targets anything that fits the criteria of A) being capable of summoned by a magician, and B) is a sentient life form.

Known by many names, these summon spirits that the user can affect are powerful, and have offensive, curative or supportive powers as their personal magics more often than not. The crux to Spirit Soul's effectiveness is that when the user absorbs the spirit in question, their contract with the owner is immediately broken and any other magician cannot forge another contract with the spirit unless the user of Take Over: Spirit Soul relinquishes that power by some means; in other words, the user of Spirit Soul has trapped the summon beast within their Magic Origin, breaking the spirit's body into magical power to use their powers at any time, effectively killing the spirit in question and rendering their body simply a puppet that the user can harness whenever they wish.

As with most other Take Overs, Spirit Soul typically grants the user of the magic a boost in speed, strength, and durability, as well as some other sort of abilities and the Magic that their target uses. However, in addition to this, as mentioned above, using Spirit Soul typically has a much more powerful side-effect than what utilizing the magic grants the user, which is saying something. The ability to completely shut down any summoning magician and use their spirits against them is utterly invaluable, as it is said that at least fifty Spirit Soul users could eliminate the entirety of the "summoning magician" subculture. Spirit Soul is strange in that most of the time, for more humanoid and goofy looking spirits, the user can choose not to take upon their full appearances, simply their powers and abilities, though it all depends on the user's personal preferences. However, aside from the basics, Spirit Soul has countless versions- there is no such thing as a Take Over Soul of this type that is exactly the same as the other, totally not an excuse to not put any more work in to the ability section.

However, the reason why Take Over: Spirit Soul is an Ancient Spell is that generally, the magic comes at a great cost, or rather, it poses a great risk to the user. Other than generally being more taxing upon the user's magical reserves when they struggle to take control of the summon beast's power and absorb them, due to breaking the contracts between the spirits and their owners, this, more often than not, alerts the head honcho of each band of spirits, meaning that if they do, the user will have to face down an astronomically powerful being in a fight that they probably won't be capable of winning by their lonesome, and even then, it can be considered an uphill battle. Because of this, despite its incredible power, Take Over: Spirit Soul was rarely used by magicians back when it was public knowledge, causing it to be designated as an Ancient Spell.

Categories of Spirit Soul

 * Spirit Soul: Celestial Spirit ( 諸召喚獣・星霊(スピリット・ソウル・セレスチアル・ソウル) , Supiritto Sōru: Seresutiaru Supiritto lit. Various Summon Beasts: Celestial Spirits): Spirit Soul: Celestial Spirit is a variation of Take Over: Spirit Soul that enables the user to 'take over' Celestial Spirits and absorb them into their Magic Origin, allowing the user to harness their powers at any time they desire. This will immediately break the spirit in question's Celestial Spirit Gate Key, rending the holder of the key's contract null and void and further magicians are unable to contract with the Celestial Spirit until the spirit is freed from the Spirit Soul user's Magic Origin.
 * Spirit Soul: Elemenian Spirit ( 諸召喚獣・元素現幻獣</rb>(</rp>スピリット・ソウル・エレメンイアン・スピリット</rt>) </rp>, Supiritto Sōru: Eremenian Supiritto lit. Various Summon Beasts: Elemental Embodiment Phantom Beast): Spirit Soul: Elemenian Spirit is a variation of Take Over: Spirit Soul that enables the user to 'take over' Elemenian Spirits and absorb them into their Magic Origin, allowing the user to harness their powers at any time they desire. As Elemenians generally do not hold a contract for long periods of time due to their own desires, this is a violation of their very natures- though unlike the pathetic Celestial Spirits, with enough willpower, the Elemenians are capable of breaking away from the user of Spirit Soul.

Trivia

 * While using Spirit Soul comes with some massive risks, it is rare, but entirely possible, to receive access to a Summoned Beast Soul without the head honcho of the spirit groups to go after the user. Alternatively, one could attempt to defeat the leader, though this is obviously, easier said than done. However, wanted criminal, Altrouge, simply tricked Tsuruko Sejren into helping her defeat the king of the Celestial Spirits.
