The Assassin Meets The Hero Lugh, Dia, and Tarte enroll in the most elite academy in the Kingdom of Alvan.

The mighty hero turns out to be a bit different than Lugh expected, however, and he ends up getting rather close with him. Being a hero isnt all its cracked up to be, it seems. When trouble strikes, will the assassin have to save the one hes supposed to kill?
