Thanks for the chapter!
Milly is right to be wary of Redia. Almost died by suffocation via breasts during the first 5 mins of meeting. As for the MC really needs to be more considerate in his language now that he's not the top Red Mage anymore. Although Claude's Family's Screen Point can't be absolute against magic although it does help to act as a lure/decoy for elementals. Should need to use mana or MP to maintain or activate considering Zeff was able to use healing magic on Claude after Cain beat her up. That and Zeff's spell buffing on Claude's blade allowed them to cut off Cain's armor so it's gotta have a limit. Then there's non-magical effects, like if constantly surrounded Cain in a magical fire pillar he'd eventually drop due to the fire eating all the oxygen around him. Wonder when will explain what emblem means and what the characteristics portray. Like are the swirls elements and lady holding the bow a heroine or goddess? Also, I thought it was a long time habit for bathhouses of having a tablet for each gender to avoid it getting spun over by accident or on purpose to avoid both genders being in at the same time?
