Principia

Physicist Rina Miura is a woman who has very little left for her. When it appears that her world is falling apart at the very seams, she is given a second chance at life, abet in an era unfamiliar to her. Transported to the late 19th century in Paris, she is surrounded by some of the greatest minds of the last few centuries; they too seem to be there in hopes of a second chance.

However, with the rising crime against women, and a yearning for more, Rina finds herself living out her second chance through the identity of her late brother.
