Muraku Hōjō is a 14-year-old male student at Kamui Daimon Comprehensive Academy during the Wars storyline. He commands the Sixth Platoon within the Rossius Union faction and later affiliates with Jenock after Rossius's reassignment. His operational LBX units are the violet-colored Gunther Yzelphar, which earned him the nickname "Violet Devil," and Magna Orthus, a later unit developed by Kageto Kiba and Kiyoka Sendou to counter Ezeldarm. He occasionally uses the MO Tyrant model in ranking battles. Physically, Muraku possesses long black hair with distinctive white sections near his temples and purple eyes featuring yellow centers. He wears the standard Rossius uniform accented by violet gloves, reflecting his "Violet Devil" moniker. Muraku exhibits a calm, collected, and strategically focused leadership style. He prioritizes level-headed decision-making and precise communication, sometimes conveying formality. He excels at tactical LBX warfare, holding the academy's top ranking position for five consecutive weeks and once incapacitating two LBX units under Haruki Izumo's command in a single battle. Despite his battlefield prowess, he interacts politely and shows genuine concern for his platoon, exemplified when ordering their retreat to prevent LBX destruction or loss. This approach fosters strong loyalty and unwavering support from his team. He serves as the primary rival to Arata Sena. Key interactions include damaging Jenock's First Platoon LBX with Gunther Yzelphar during their first encounter, though Arata landed a hit using a Hyper Energy Bomb. Muraku later confronted Arata at the academy gate to acknowledge this damage, initiating their rivalry. He oversaw the defense against Jenock's raid on Rossius territory and engaged in strategic discussions with Arata about LBX's purpose and the escalating conflict within Angel Piece. Following Ezeldarm's capture of Rose City, Muraku and his platoon joined Jenock, where he cautioned Arata against the academy's hostile influence. Muraku participated in joint operations against adversaries like the Bandit LBX, observing Arata's unexpected power surge. He pragmatically supported a multi-faction alliance against Seredy Kreisler, asserting to commanders that protecting Second World superseded factional orders. As a member of the Student Council alongside Haruki Izumo and Sakuya Hosono, he strategically suggested during budget deliberations that Jenock members target top-ranked Hikaru Hoshihara to improve their collective ranking position, indirectly challenging Rossius's numerical advantage. He maintained the Rank 1 position in the academy's Ranking Battle system for five consecutive weeks, frequently battling and defeating Vanessa. His tactical insight extended beyond combat; he advised Rossius leadership on resource relocation after territorial loss in Rain City and witnessed the departure of LOST-affected students.
