Seth, Mélie, and Doc encounter new allies in Caislean Merlin – the stronghold of the Knights-sorcerers, a group that is also after the monster called Némésis. Seth’s adventure accelerates with the addition of Ocoho, a girl who hopes to become a Knights-sorcerer, a farewell with Mélie and Doc, and a clash with the malicious Merchant-Barons! And all this with the Inquisition still at his heels!
A young sorcerer. He parted ways with Alma, who raised him as a parent, to begin a great journey in search of the legendary Radiant. Although he's clumsy and tends to mess things up, he's always cheerful and true to his own beliefs. Coming in contact with a Nemesis gave him the curse of horns on his head, and for some reason, the Inquisition sees him as a threat because of this. When his own power rampaged out of control, he was so frightened that he left Melie and Doc without even saying goodbye to travel to a new land alone.
A young sorcerer whose poofy red hair is her trademark, and an Ambush Hunter living in Artemis Academy. She is kind, mild-mannered, and a bit airheaded, but when her curse kicks in, she abruptly switches to a very combative personality. She normally uses only defensive magic, but when her curse is active, she specializes in offensive magic. She felt quite a shock when Seth left her behind to depart on his new journey...
A researcher at Artemis Academy. Like Seth, he was infected after making contact with a Nemesis, but he chose not to learn magic. He's an extreme coward who runs away from any kind of danger, yet he's still constantly getting caught up in troublesome situations. While in Rumble Town, his curse of molting caused him to revert back to a child. He's in love with Miss Melba.
A young girl in training to become one of the Knights-sorcerers, the protectors of Caislean Merlin. She is cheerful and good at looking out for others.

She has known Mordred and Sagramore since they were young
An Inquisition captain who cracks down on sorcerers. He gives the impression of being quite lazy and listless, but he possesses a strong sense of justice and has earned the trust of his subordinates. He seems to acknowledge the abilities of Seth, his primary target, and temporarily fought alongside him in Rumble Town. He has parted ways with his men to respond to a summons from General Torque, fully prepared to take responsibility for his actions.
A mysterious sorcerer, wrapped in bandages from head to toe. He has the power to control Nemesis and seems to be searching for a certain Domitor, but his true goal is a mystery. In Rumble Town, he fought alongside Seth and the others to resolve the conflict. He is quite skilled, but has such a terrible fear of blood that he will flee from battle at the sight of a single drop. He always refers to himself as "Grimm" when speaking.
A veteran sorcerer who raised Seth as a parent. A Pursuit-style Hunter. She always believed that humans and cursed sorcerers could never understand each other, but Seth's actions have made her reconsider her belief. Although she seems angry all the time, she also worries about Seth. She has lost all memories of her past and can't remember anything from before she met Seth.
Melie's friend who goes everywhere with her. He likes the combative Melie that comes out when her curse activates far more than he likes the normal Melie. All he says is "pyui."

A knight-sorcerer apprentice. Well-known and loved by the people, and known widely as the “Nemesis’ nightmare.” Along with Sagramore, he is one of the most promising young Knight-sorcerer apprentices still awaiting their ordinance ceremony. He worries about Ocoho, his childhood friend, and always helps her when she’s in trouble.
A knight-sorcerer in training. Well-known and loved by the people, and known widely as the “Nemesis’ nightmare.” Along with Mordred, he is one of the most promising young Knight-sorcerer apprentices still awaiting their ordinance ceremony. He is quite serious and doesn’t say much. He has a very strong will and keeps up his training even when not on missions.
A skilled Knight-sorcerer who’s in charge of both leading and training apprentices to the order. He believes authority should be respected and rules should be upheld, and during missions, he considers the spell Gysoni essential for establishing harmony with his companions. When it comes to fulfilling missions, he doesn’t care how others see him.
The strongest of the Knights-sorcerers, clad in gold armor. The guardian of Mordred and Sagramore. In contrast to Lord Brangoire, he believes that the resourceful should lead the people as a hero and considers great individual strength to be essential, as evidenced by his flashy appearance.
One of the Merchant Barons who control the world’s economy. A greedy merchant of death who sees the discrimination of infected people and the Nemesis disaster as nothing but an opportunity to make a profit. He has brought the other Merchant Barons along to Cyfandir after seeing the potential to make a fortune there. He has a gentle demeanor, but at times, a sharp glint sparkles in his eyes.
