4. Theorize about the importance of astrology in HnG.
Athena is definitely a Capricorn. Highly compatible with Scorpio, which is Hayate.
Hata did say something like.. "Eternal love for Athena" and "Eternal protection for Nagi"
Guess that the Athena fans had it right from the get go. It's gonna end with Hayate x Athena.
