Lanfeust in a young boy living in Glinin village. He is the pupil of the blacksmith Gramblot and is engaged to C'ian.
His dream is to become a great hero but it seems unlikely... Until the day a knight comes to his village to repair his sword shattered during the fight against a troll.

Readers of the Lanfeust of Troy (a French language long running comic series) will feel a sense of familiarity, as its basically the same story, in manga format. Which the title also gives away.
