Akihiro Belial

Akihiro is the heir of the Belial family and a main character of the Einstein isekai franchise.

Appearance
Akihiro is a fairly tall, slender young man with magenta eyes and shoulder-length, light pink hair, which he usually wears in a low ponytail. His standard outfit consists of a white shirt, plain black or gray trousers, and dark leather shoes, sometimes combined with a black, thigh-length coat. Additionally, he wears half-rimmed glasses, which he only takes off during major physical activity or to sleep.

Einstein Albert
Initially, Akihiro looks down on Einstein for not being able to use magic, but when he witnesses first-hand how capable Einstein is in regards to science, this contempt quickly changes into admiration, to the point where he practically begs Einstein to make him his assistant. Akihiro proves to be very capable in that position, always trying his hardest to keep up with Einstein’s scientific rants. His feelings towards Einstein seem to be romantic at first, but later shift into a more platonic sense of admiration (although Akihiro’s interest in Einstein’s work and research remains unchanged). Post-canon, Akihiro's admiration and respect for Einstein diminishes greatly because of a certain event, even hating him at one point before he calmed down, but never went back to his former way of following Einstein around and being in awe like he was before.
