Jonas Jr. Rogue, A.K.A. Emerald, is a senior at Hope's Peak High and one of Joseph's party members. He is known to be a skeptical, logical, blunt, composed, mature, ignorant, and sharp. Emerald is known for his blunt and charismatic behavior and unamused by ignorant and prideful people and childish acts of immaturity. His logical thinking is also that of being devoid of any means to engage social activities such as friends, something he doesn't take amusing. However, after the death of his brother Vermillion and his butler Yama, Emerald became increasingly lost in thought out of grief. Fortunately, his newfound companions/friends helps soothe the burden, making him a more mellow and encouraging fellow. Emerald is continuing to do his best to make sure his company runs properly and straight.
