Hemera

Hemera (ヘメラ, Hemera) is a Caster Magic and Lost Magic that is mentioned in the Tripendium of Elysia. It has only been seen practiced by the Eternea Family. The "Law of Hemera" is as follows: stand not consumed in the whirlpool of your emotions, but with them. With this law, users of Hemera can synchronize their Eternano with their emotions, mostly being used to create intense beams that can pierce through objects. Hemera also changes depending on the emotion that is being used to power it. An emotion such as joy can be used to protect allies and even empower them, anger can be used to destroy. Toro, for example, used stronger emotions such as wrath to augment her abilities. Other emotions can affect the efficiency of the magic.

Description
To activate Hemera correctly, the user must limit their emotions. This includes happiness, anger, and fear. Without limiting these emotions, the magic could actually harm the user instead of helping them. When these emotions are bottled up in the user, they grow enough for them to spill into the user's magical abilities. When the emotions are unleashed, they are used as a weapon. With each punch, kick, and yell, the user is backed by their own feelings.
