Valkyrie's Treasure

Most students at the Holy College have heard the rumor that the daggers Valkyries use double as a key to a chest on top of the academy tower. Since the academy strictly prohibited students from accessing the top floor, nobody has been able to verify this rumor. Even though the actual treasure might not be as great as students imagine, just gossiping about it brings joy to the girls who are bored out of their minds repeating the same routine everyday.
