Eitoku High School (叡督学園, Eitoku gakuen) is a location mentioned in AI: THE SOMNIUM FILES.
- Hitomi Sagan (Class of 2001)
- Renju Okiura (Class of 2001)
- Manaka Iwai (Class of 2001)
- Shoko Nadami (Class of 2001, potentially)
- The name "Eitoku" may be a pun: "eito" is the transliteration of "eight," and "ku" means "nine," making the name "89."
- In the Investigation Trailer for AI: THE SOMNIUM FILES, Shoko Nadami is stated to be an old classmate of Renju Okiura and Hitomi Sagan, meaning she would be a student of Eitoku High herself. Despite this, Hitomi claims that she first met Shoko at her wedding with Renju. This could mean that they never socialized with each other when attending school, simply just graduating on the same class year.
