Return Of The Runebound Professor

In this Viking world, young women train to become Valkyries, and battle magicians, to join the Vikings on their conquests. But for this, the Valkyrie needs a strong slave, a so-called træl, to extract energy from and create magic. Aske, a broken slave, gets bound to Hilda, a Valkyrie in training, and thus begins his life as a træl. Natalia Batista’s submission for the 100th Tezuka Manga Award contest
