Knights & Magic Manga

A brief description of the manga Knights & Magic:

In our world, the protagonist was a brilliant programmer and at the same time an otaku and a fan of giant fur robots. But after his death, he was reincarnated in a different world, like Ernesti “Eru” Echevalier. In this world, the home country of Eru is protected by the Knights who control the giant furs known as the Silhouettes of Knights. Dreaming that one day he would be able to pilot such a robot himself, Eru and his friends Arcid and Adeltrud Oltere learn magic and go together to their goal.
