The latest Shonen Jump issue reveals two new characters and their corresponding character art. Special thanks to @kazu4281 for the scan.
Rokurou(????, see rokurou)
Voice Actor: Daisuke Kishio
Character Designer: Daigo Okumura
"You know, right? I may look like this but I've got a strong sense of duty."
Rockrow is the same character with the dark hair who appeared in the latest trailer here. He is a free-spirited young swordsman who keeps his reason even in the face of the daemon. Apparently he feels obligated to follow Velvet but for what reason we don't know for sure.
Eleanor (????, erenoa)
Voice Actor: Ami Koshimizu
Character Designer: Kosuke Fujishima
"I shall not avert my eyes. This is the reality of the path I've chosen to walk, after all."
Eleanor is a completely new character we haven't seen before. A woman who belongs to Seiryou, an organization for fighting daemon. She is gentle and caring to everyone except those who go against the Seiryou.
The scan also talks about the LMBS for the game which is now known as theLiberation-LMBS. You can map Artes to the Circle, Square, Triangle & X buttons. The number of Artes you can perform is dependent on a character's Soul Gauge (SG). With every enemy you defeat, your SG increases. Each battle starts you off with 3 SG.
