S1·E1 The Child from the Mist

Grougaloragran, a mysterious and ancient entity, appears one with a baby carriage. After defeating a mysterious foe with powers over time, who wants Grougaloragran's life force, or "Wakfu", Grougaloragran comes across Alibert, who is quitting his profession as a bounty hunter after almost taking a innocent man to jail. Grougaloragran leaves the baby carriage with Alibert, believing that he will be a good father to the baby inside. He also leaves a message for the adoptive father, along with a baby Tofu (Bird). 12 years later, Alibert has opened an inn and established a small town. The boy, now called Yugo, believes himself to be a ordinary boy until he discovers that he has the ability to create portals. He puts it to the test when a monster rampages though town, ending up at his Inn. Ruel, who was passing though town, teams up with Yugo and defeats the beast, which turns out to have been a Iop possessed by a demon trapped in an item, in this case a sword known as a Shushu. Alibert, seeing Yugo's power, decides to tell him the truth: that he is adopted and that his real family is out there somewhere.
