Ayuna Takahashi

Ayuna Takahashi is is a student at Takahasi’s Academy for Misfits Witches and Mages and is the leader of Ayuna's Superior A Team. Ayuna is also Master Takahashi's granddaughter and an exceptional student. Ayuna along side some others, is one of the strongest students at the Academy being apart of the Top Teir 13. Tanila is an extremely skilled mage who practices in Darkness Magic and Sword Magic. Her mastery over her magical abilities has given her the alias "The Dark Maiden" (ダークメイデン, Dākumeiden) and given her the ranking of an S-Class Mage even though she is merely a high school student.

Swiftblade
Swiftblade (スイフトブレード, Suifutoburēdo) is used by Ayuna like other katanas, is a samurai sword with a shiny silver hilt and a slender curved single double-edged raven colored blade with the exceptionally sharp edge. Ayuna’s sword was handed down from generation to generation in her family. Until Ayuna was gifted the sword, the katana was gifted to only men in the family. Ayuna’s sword is known to be able to cut through every single material that has ever been crafted by man. The blade is so sleek and precise that whatever the sword aims at or swings at, it cuts down almost completely. The blade is able to cut down reinforced titanium walls like knife going through hot butter. The blade never misses a target on, ever. The blade was made with a special type of metal making it nearly impossible to break and making it impossible to rust. The blade is exceptionally long stretching to a length of 74 cm. The edge is specially designed so that she can touch with her thumb while gripping it so as to draw blood, and grooves specially designed to spread her blood through its entire blade. Once loaded with her blood, it is a deadly weapon against any other vampires and monsters however, it does not do anything against regular humans or other beings. Because of it exceptional length and striking power, only Ayuna is able to wield it effectively. Because of its remarkable power, the katana has been dubbed as “The Sword that Cut Down All-Man” (オールマンを切り倒す刀, Ōruman o kiritaosu katana)

Abilities
Immense Durability: Due to Ayuna being a vampire, she has a biology that differs from humans, changing the internal workings of their bodies as soon as the transformation is completed. Many of the changes done to the body tie into her status as the undead, however, others contribute to the vampires existence as a whole. Quite similarly to a Slayer, her lungs and stomach are much more durable than a normal humans, and she can breathe in or ingest toxins with little to no harm to herself, though this appears to vary with the amount taken in. Her body is designed to physically be superior to a human's in every known way. Physically, she are more than capable of overpowering a human, rendering them powerless and easy prey; however, this is not always the case. Such humans such as Ren Takahuma is able to easily over power Ayuna with his insane physical strength and power In terms of durability, her skin could be said to be considered more "hide" than skin, as it has become more resistant to blunt force impact, certain weaponry, and even lower class spells.

Weakness to Immense Exposure of Sunlight and Silver: Ayuna’s skin is also known to be highly susceptible to sunlight because she is a vampire; But since Ayuna is an extremely strong vampire gaining her the rank of a noble, she only feels mild discomfort in sunlight. Notably, silver is the primary weakness of a vampire; silver is a metal that holds unique Eterano within it that reacts to a vampire's own powerful magical energies; the very same that keeps their body functioning properly. Due to silver's properties as a very effective conductor of heat and electricity, the eternano within the silver creates a powerful reaction when touched by a vampire in particularly large amounts, the eterano enables the silver to absorb the heat and bioelectric potential from the vampire, (the ability for nerve endings to actually give commands), and therefore disabling them if struck with a high enough concentration and/or quantity. The effect only takes place with a considerable quality of silver, as a vampire can hold small silver items without critical damage to their body, and it is only temporary and can be removed if the silver itself is removed from the body of the vampire.Rapid Regeneration: Because Ayuna is a vampire, she is very difficult to successfully kill. Due to being undead, she cannot die in the natural way; they do not die of old age, and are unable to succumb to diseases and the like. Even assaulting a Ayuna’s body in an attempt to slay her will often prove fruitless, as she possess a very strong regenerative factor; she can even regenerate from being vivisected, or having a fist-sized hole blasted into her torso. There is a limit, however, to her remarkable regeneration. The her vampire body is linked together by their magical energies; if her limbs is severed, she can restore it by simply reattaching the limb. However, for a complete regeneration, the severed body part no longer has to be "alive". As such, if a limb was severed from her body, but kept safe, hidden away, it would never regenerate; she would have to find the limb themselves and reattach it. If her head is severed, she can survive this and reattach it, however, if it was to be taken and locked away, hidden, she would remain conscious and alive, but unable to regenerate her head as her body would never decay. The only way to ensure a Ayuna dies when she is killed is to completely destroy her body; she are unable to regenerate without an 'anchor' so to speak.

Vampires no longer possess a beating heart, however, blood still flows strong within their veins; it is implied the strong magical energies of a vampire carry the blood throughout the body, and it works identical to human blood. These same magical energies are what tie the vampire body together, and enable them to perform powerful regeneration. While a vampire has to breathe, as their blood still requires oxygen as much as a human does, they are able to hold their breath for much longer than a normal human, around a full hour at any given time. This would imply that the transformation from human to vampire increases the amount of myoglobin in the body tissue, allowing for a vampire's body to hold oxygen far longer than that of a human. True to the statement, the flesh of a vampire of much darker than a human, bordering on black instead of the normal red. The flesh of a vampire also takes three decades to fully be digested when eaten.
