I just finished reading vol 14 and have to ask why does Euclid Lucifuge seem to hate Grayfia so much I mean it looks like they are the last members of the House of Lucifuge so shouldn't they get along since they are siblings. Also does anyone know what the relationship between Euclid and Sirzechs is like?
