Ellis Warrior

Ellis (エリス) is a minor character in the Toaru Majutsu no Index series. He was the first attempt at creating a Magician-Esper hybrid.

Background
Not much is known about Ellis, however, he was an esper 20 years ago before the start of the series, indicating that the Power Curriculum Program and espers already existed at that time. Ellis was an esper chosen by Academy City to be part of the joint institution created by a secret cell, within the Anglican Church to create a magic and esper hybrid.

A young Sherry Cromwell was assigned to teach Ellis magic, and became great friends with him. However, when Ellis tried to use magic, the contradictions between magic and AIM proved fatal for Ellis, which burst his blood vessels and severely injuring him. At which point, operatives of the Knights of England came and destroyed the institution that Sherry and Ellis were in in, after the higher-ups of the Anglican Church realized that they were in contact with the science side, under the pretext of preventing the leakage of magic teachings and secrets, however, the true intention was because they didn't want magic to have any contact with science. The knights then killed Ellis, who used himself as a shield providing with Sherry enough time to escape.

The event would forever traumatize Sherry and would later dedicate her sorcery name and the names her golem in memory of him.
