After Hayate stated that if anyone defeats him will get the Sanzenin estate, Hayate decides to quit being Nagi's butler!
He told me to keep it a secret, 
but I just couldn't let it go.
Me dijo que lo mantuviese en secreto, 
pero me resultaba imposible.
Ele me disse para não te contar, mas
não posso deixar as coisas desse jeito.
