Know one thing I LOVE about this series... the characters' names.
I can't say everyone single one is real, but they all feel realistic, inside of the naming convention of their respective countries. Sigrid Bachman, Fabio Zaccaroni, Narcisse Maugham, I can say if someone in real life would be called any of these (at least the surnames, the names I know exist, specially Sigrid and Fabio), but in a story like this, these names do sound real.
I understand that it is difficult to name characters outside of your own country but in manga, I see so many stupid "foreigner" names, so I respect Kore-sensei a lot for at least putting some work into naming.
Fabio and Sigrid's little "sibling" was cute.
