Magician-Esper Hybrid

A magician-esper hybrid is a person who can use magic and esper abilities. However, since an esper's AIM is incompatible with mana, which is the source of magic, the hybrid will suffer severe damage from performing magic.

Hybrids
The only "successful" hybrid is Tsuchimikado Motoharu, as a result of him joining the Power Curriculum Program in order to complete his ruse of being an ordinary student, him being an opertive sent to spy on the city. However, this is only due to his esper ability being able to repair any damage inflicted to him, which could fail at any time. Because of his hybridization, Motoharu a talented magician in his own right, can only perform magic a limited number of times before being grievously injured.

There was an experiment to create magician-esper hybrids by Academy City which involved sending espers to learn magic, which Sherry Cromwell was a part of. This experiment was a failure not only due to the injuries the subjects sustained from using magic, but the Knights of England killed off the subjects, including Ellis, Sherry's friend, due to the belief that the experiment was against the truce between the magic and science sides.

There is no currently no way for a magician to become a hybrid without the dangers present with the incompatability of AIM to mana.
