But I will not become the monster they saw in me! Despite suffering from persecution all his life for being an infected and sorcerer and his own dark desire to destroy everyone who discriminated against him with magic, Seth won't do it because he refuses to become the monster they thought he was. He doesn't really show this trait later on in the manga either. This is greatly toned down in the anime, where the egg hatches on its own and Seth doesn't make any such stupid decisions. Don Bossman sarcastically points out later on that Seth actually did far more damage than the villains. He's so eager to prove that he can fight Nemesis that he deliberately makes a Nemesis egg hatch in the middle of a town with civilians around, causing no small amount of damage afterwards, with the bonus of tying up two kids to take them to "safety" (actually to the building where everyone is held hostage). Destructive Savior: His big problem in the introduction arc.
He even mocks him to buy time because he's running out of energy and the magic protecting his broken arm is wearing off. Combat Pragmatist: Seth feints Konrad and knees him in the face during their fight.As Yaga put it, naming your attacks is a way to mnemonically link the name with the intention, making the casting of the spell instinctive. Although, there is an in-universe explanation for it because of how Fantasia works. Calling Your Attacks: He does this all the time during fights.Barrier Warrior: Like Mélie, he can create shield of Fantasia to block attacks.He would have been killed by adults at the stake if Alma didn't save him. All of the Other Reindeer: As a child going from islet to islet with Alma the horned Seth faced terrible discrimination because of people's belief in the Inquisition's lies, getting beat up by children who even stabbed him to find his "demon's mark".In the anime he's puzzled when Alma tells him about the Radiant, doesn't seem to know what the Inquisition is, isn't very good at flying and can't use any magic other than his "Titan Punch" (just a Fantasia-charged normal punch). In the manga, he's the one who first brings up the Radiant, he knows not to reveal his barehanded magic to the Inquisitors, can perfectly ride a Flying Broomstick and can use basic spells like Repulse or Meteor Drops from the start. Adaptational Dumbass: A very strange example − the first two episodes made it seemed like anime!Seth was less impulsive and reckless than his early manga counterpart (see Destructive Savior below), but then the following episodes make him much more ignorant than he initially was.His goal is to find the Radiant, the source of all Nemesis, to destroy it and end the infected's suffering.
The protagonist, a reckless teenager infected by a Nemesis back when he was a child, which gave him a pair of small horns. Voiced by: Yumiri Hanamori (Japanese), Christopher Llewyn Ramirez, Cristina Vee (child) (English)
