Ruijerd Superdia (ルイジェルド・スペルディア) Ruijerd is the former leader of the Superd warrior group, once serving under the demon Laplace with unwavering loyalty. During the Laplace War, the Superd race was cursed through their spears, causing them to lose control and commit atrocities against allies and civilians. This led to the widespread belief that they were savage monsters.
After the Mana Disaster, he meets Rudeus Greyrat and Eris Greyrat. Together, they form the party Dead End and join the Adventurer's Guild to earn money and fund their journey back to the Central Continent, with Ruijerd adopting the alias "Watch Dog".
