- Elves exist (I mean, duh the sensei is an elf)
- The sensei is the daughter of the Elf patriarch (essentially their King)
- Elves doesn't have a lot of interaction with the human countries
- The Elf are helping the sensei to gather her students
- Elf are embassadors of peace and are trying to stop the never ending conflict between Humans and Demons
- Elves are seen as heretic by the Goddess Religion
- The main religion of the Sariella Country is the goddess religion
- Right now Kumo is on Sariella
- In the last years a human trafficking group has appear and it seems to be mostly focused in babies
And all of this end with Kumoko seen elves for the first time and they're trying to kidnap Sophia (the baby). And then everything starts to connect:
- Sensei never said how she managed to gather the students she have under her care
- If the other students are safe why Shun. & Co have never seen them or at least had some contact (letters)
- Do you really thing that 11 families accepted to give their children to a complete unknown person
- The reason why sensei wanted Shun & Co in the same academy was to make them leave their castles and be able to kidnap them
