Insouciance? Don't think I've heard that one before. Must've been on somebody's word of the day calendar or something considering how many synonyms it has that people would be more familiar with.
@Notsuki_Ame That threw me off too
Considering they were calling her a Goddess and Seraph moments before, at first i thought they saw Vampires as beings worthy of worship, which would be weird
Then the next panel got me thinking that maybe people figured it out but they kept quiet and didn't alert the guards because they're grateful to her
"Thanks to my support from the people. Nobody (outside them) seems to have found out"
I mean bowl-kun called her a saint rather than 'vampire' so the rumor spread like that
