Akira Nishino

Akira Nishino is the older brother of Akane Nishino.

Personality
Akira has shown to be obsessed in studying magic and unlocking its secrets and will do anything if that meant he can understand and control it. While a brilliant man, his intellect is overweighed by his arrogance. His belief that he can control any situation, especially the tampering of unpredictable magical energy caused him to completely ignore the potential consequences.

Despite claiming everything he had done was for the good of humanity, his condescending attitude towards others, his use of human test subjects and the lack of remorse for the harm he caused proved otherwise.

In short, Akira Nishino was a madman who will sacrifice anything and anyone to satisfy his scientific endeavors.

Abilities
Akira is just an ordinary human with no magical powers whatsoever. However, he has shown himself to be a genius scientist by Earth standards, capable of experimenting with magic and creating the "First Knight".

Akane Nishino
Despite being siblings, the two had a tense relationship. Any familial love he had for his sister is completely non-existent as not only did he use her power to gain political advantage but also experimented on her without hesitation. When Akane went missing, Akira did not bother searching for her and instead went off to find a new test subject for his experiments.

Natsume
After 'Natsume' was brought to Messiah by Akane, Akira took custody of the presumed "Awakened" person and was ecstatic to discover that she had even more magical potential than the "First Knight". While intending to experiment on her, he was mortally wounded by Yuka before he got the chance. In his final moments, Akira was shocked when Natsume got up after seemingly being killed by Yuka and looted his laboratory, introducing herself as Beta from Shadow Garden.

Mordred
Akira found Mordred's severed head and intended to use it in his experiments by injecting Natsume with his magic-infused blood. However, he was ultimately assassinated and had the head stolen from him by Yuka before he could implement his scheme.
