@debauchery Thought the same thing, especially when the parallels with Christianity are already there from day one with how the religion works in the world of Fire Force (Christian churches, nieces, sister covents, Latóm as a substitute to Amém). The only thing here is that really deviates from the Christianity parallels is Mary having two children, and they have a respectable age gap between them hahaha.
The woman got impregnated twice, or we will have Sho and Shinra being actually twins but by some bullshittery mumbo jumbo reason Sho was kept in stasis for a few years (explaining his white hair and all, and no, I don't think he is an albino).
But that is just a wild theory for now.
