Foxfire

Foxfires are, as the name suggests, round balls of fire that float around a kitsune, typically behind the kitsune. Foxfires aren't ordinary fire, they are with the kitsune from the moment they are born and are magic-infused.

Foxfires are usually red, but the more magic ability the kitsune has the more blue the fire is. In addition, the kitsune the fires are born with can use a little bit of their energy to hide the foxfires, as well as reveal them. The kitsune may also use a little of their energy to move the fires at the user's will. When the kitsune is not forcing around the foxfires, the fires will trail behind the user. This energy usage is so little that the kitsune does not even feel the loss, but in the case of dying or severe exhaustion the energy drain may cause the final exertion for death.

When the foxfires are hidden, the do not just go invisible. Each fire moves inside each tail the kitsune has, one per tail. This does not cause any type of pain or damage, and does not take up space inside the body. It is just stored inside until the kitsune reveals them. Additionally, for each fire hidden, the fires give extra energy. But the kitsune must be careful, because if they rely on this energy and then suddenly unhide the fires, it can cause massive emotional pain.
