Body Key: Inner Beast

Body Key: Inner Beast(ボヂ キ イナー ビスト Bodi Ki: Inaa Bisuto) Is a deadly spell used in Key Sync.

Description
One of the most deadliest spells known, it is often used in   Body Key Style that any user could preform on themselves. In human's, there is said to be a beast inside, wanting to find it's way out and unleash it's fury on the world. However, with human's, many have learned to control this beast and keep it under control. For this spell to begin, the user must first throw away all forms of rational thinking, clearing their minds of any thoughts as their instinct begin's to take over. When that happens, the user moves the key to the middle of his forehead, then inserts the key in and turns it. When the spell is activated, the beast inside the user is released, releasing all the limit's on their human body as the beast begin's to take over, augmenting their physical appearance, their size, and even their mass at times. The change depends on an individual's own primal instinct's, often resulting in different forms of changes. However, this spell is the deadliest due to the fact that the inner animal of all is released and can run wild, and can only last up to five minutes before the user must regain control and relock the beast inside of him, otherwise they could remain their savage form forever.
