Lilith

Lilith has a chūnibyō-like personality, being an attention seeker who loves speeches and to give evil laughs. She is a scientific genius with faith in science, however, because of her intellect, Lilith is overconfident, cocky and irresponsible, just testing her inventions once before implement them. She is also an anime otaku, and although Lilith looks self-assured, as an otaku she is spoiled, antisocial, faint-hearted and overreactor, self-isolating when she is mistreated.
