Take Over: White Snake Charmer

White Snake Charmer (白蛇使, Hakujasha) is Karasu's main Take Over spell after he lost his ability to use Lightning Dragon Slayer Magic. It allows him to take over the appearance, abilities and powers of the legendary beast Yamata no Orochi (八岐の大蛇, Eight Branched Giant Snake). However due to the immense power of the beast, Karasu is unable to utilize the full power of this spell without his own body being taken over by the very same creature.

Description
To utilizing this spell, Karasu will draw out the soul of Yamata no Orochi and began to wrestle for control of the beast, causing the very air around him to suddenly become heavy and the ground to start to tear up. After Karasu successfully takes control of Yamata no Orochi, he will appearance will undergo a massive change.

When undergoing the transformation, Karasu's skin will become white and scaly, akin to that of a snake; due to the nature of the scales, Karasu will often shed the top part of his outfit to prevent any discomfort on his part. Not only does his skin become snake-like but his eyes and ears as well. His eyes are now more serpent-like, having purple markings that appear like eye make. His ears, as mentioned, are now serpentine ear-like protrusions, that he can use to hear from great distances. Finally, the most interesting feature that Karasu has in this form is the snake appendage attached to his spinal area. This snake is able to act on its own free will, alerting Karasu when his is in danger or is in an illusion of some kind. With White Snake Charmer, the user is seen to become more flexible and fluid, allowing Karasu to move at much faster speeds and with much more heightened reflexes that make him seem almost as if he was a snake moving on the ground. It has also been seen that when he enters this form, he is able to use the power of Darkness Magic and Poison Magic, allowing him to use them to create new powerful spells along with his Take Over Spell, making it one powerful spell to use.

Magical Abilities
Darkness Magic (闇の魔法, Yami no Mahō): Darkness Magic is a Caster Magic which utilizes the element of darkness. Darkness Magic is a Caster Magic which draws on the negative emotions of the user and manifest it in a physical form, the element of Darkness. While Darkness Magic is not inheritably evil in a sense, it does give off a feeling of despair to opponents that fight against a user of this magic due this magic releasing the malefic nature of the opponent out into the world. It is said that this magic was the one of the first attempt at creating a Black Art, though it was later used as a base for later Black Arts that came to exist. This Magic allows the user to utilize destructive abilities; it is triggered by going by the opposite of the 'magic = feelings' concept—by fuelling their magic with negative feelings, the user is capable of initiating the usual fusion of eternano and magical power, only manifesting magical power in a dark and malefic nature; this is known as Darkness Magic.With this type of magic, the user has absolute dominance over the element of shadows; and thus, darkness, night, and any dark-related elements. This Magic has a physical form used for destroying objects, blocking enemies' attacks and picking up objects; consistently, it is a pulsating crimson. When using it, the user more often than not shapes their attacks into the form of waves or arcs of shadows, which they can use in various ways. The shadows can be channeled to a variety of effects, both as an absence of light and a solid substance: one can also control and manipulate the beings that exist there, create and dispel shields and areas of total darkness, create a variety of constructs and weapons and, teleport themselves through massive distances via shadows; being able to take out multiple opponents with just one attack and capture people, sinking them into the depths of their shadow.
