Nova

Nova is a minor character in the Einstein isekai franchise.

Sibyl
Nova admired his father greatly as a child despite never having met him, finding out details about him because of his mother that seemed to rarely talk about him because in the end, he left her for another woman. When she did, though, she would not stop for hours. He admired his father's fortune telling ability and always hoped to get it, too. He never gave up searching for his father either, even if he doubted that he would ever find him or anything related to his disappearance. The day his own fortune telling ability made itself known however, he thought that maybe he should have stayed unaware after all...

Lucifer
Nova is unsure of how to feel about his master. On one hand, Lucifer has made it possible for him to live this long to meet Masahito Itou and Hana Fujiyama, gave him a purpose to fulfill and gave him an answer to what he wanted to find out so long ago, but on the other, the man had kidnapped him and forgot about him without a second thought. However, Lucifer is still the ruler of hell, so Nova cannot blame him too much and just enjoys the freedom the other gave him for now. Nevertheless, he would not betray the others to fulfill his master's orders anymore.
