Six Paths of Reincarnation

The right eye of the user will be red, while the numerical kanji of the currently active path will be displayed on the eye in black color. Rokudo Mukuro, the original owner of this ability was almost always seen with the sixth path active, so I have made it such that the sixth path is the default path for the MC.

First Path: The Realm of Hell (Jigokudo/Niraya Path)

It allows the user to create illusions. When mastered, the illusions will be able to warp reality. The 'real' illusions will not facilitate creation because the illusion will disappear once magic is stopped being fed to it, but the damage these illusions make will always be reflected on reality.

For example, the original user was able to make an illusion which replaced damaged organs. But the illusion had to be maintained constantly, or else the damage would come back.

Second Path: The Realm of Hungry Ghosts (Gakido/Preta Path)

It allows the user to perfectly utilize the skills of people they possess. In canon, it is seen when the user possesses someone and then triggers this path in the possessed body. I have added a factor to it such that it gives the user an incredible learning capabilities when they use it while in their own body.

Third Path: The Realm of Beasts (Chikushodo/Tiryagyoni Path)

While using the path, the user can summon and control animals. One change I made is that when mastered, the summons can be magical creatures as well. The summons will deactivate when the quantity of magic that was used to summon them dies out. When the path is not active, the summons which were already made will be just following the previously given directives, instead of being under complete control. They will still need to maintain a connection to the user to stay active though.

The following three paths had to be changed a little in order to fit the magical world.

Fourth Path: The Realm of Demons (Ashurado/Asura Path)

The fourth path gives the user a tremendous boost to their raw magical power and bathes the user's right eye in Indigo flames. The quantity of the flames is an indication of how much boost is remaining. Once the flames run out, the fourth path needs to recharge before activating again. Even when inactive, this path will be absorbing ambient magic to recharge itself.

Fifth Path: The Realm of Humans (Ningendo/Manusya Path)

The fifth path is different in appearance that the kanji on the eye is white. Once activated, blood flows out from the eye while the veins in the body bulge and a shroud of magic surrounds the user. This path gives the user absolute control over their body and senses. As a result, the speed and the reflexes of the user are increased manifold. It also gives the user a minor healing factor. Due to the nature of this path, it can be used to easily form muscle memory and facilitate muscle growth. Although, due to the physical strain placed on the body, it can only be used once per day, for a limited amount of time.

Sixth Path: The Realm of Heavens (Tendo/Deva path)

The sixth path allows the user to completely possess and control targets when the user's magic is injected into the target's bloodstream. During such a possession, the target's right eye will transform to look like the eye of the user. Once the user gains more skill, they can even possess multiple targets at the same time. The user will not be immobilized during the possession since the senses will be shared instead of complete immersion. All this extra sensory information is facilitated trough the path.

This path also allows for a partial possession where directives are placed into the target's mind and they are carried out when necessary. The injection of the magic remains the same, in order to place the directives. But they can be activated anytime once placed. This is a more subtle possession and will not transform the target's eye, in order to share senses. It is quite similar to the imperius curse.

In addition to this, this path also provides the user with heightened capability for mind magic (occlumency/legilimency).
