Black hair. Red eyes. The whole lapileon bloodline has poisonous blood that kills anyone who touches it. The present Grand Duke, known for being a "bloodthirsty war fiend" after his victory in the war against Schwartz. Therdeo is cold and standoffish to discourage people getting close to him. He is awkward when it comes to emotions and clumsy expressing his feelings. Pushes people away to protect them and in fear of hurting them. Possessive and obsessive when he cares for someone.
