Formerly Rank 137. Blazing Rank 20,000. The Blazing Rank is a system assigned to students outside the top 100; when a rank-holder kills another student, their number increases. The higher the number, the greater their power. In his original world, he killed every single student. Through the effect of his Blazing Rank, his ability to "See Boundaries" evolved into something that monitors, understands, and manipulates everything. In his solitary academy, he has established the "Law of Prayer," which dictates: "Continue to offer prayers for what you have lost." Techniques: "Ghost Shadow": Uses the shadow directly beneath him to move at ultra-high speeds, similar to surfing. "Ash Rope": Reduces the boundary—the distance—between himself and the target to zero, forcing them into an immediate infight. "Afterimage": Dives into shadows for the split second before an attack hits, making the opponent falsely perceive a hit and inducing a lapse in guard. "Stygian": Eliminates the boundary between the event of attacking and the event of the attack hitting. To the victim, the trajectory of Raven's knife appears pitch black. "Blackout": Slashes through space with his knife, dragging surrounding objects into the rift. Even he does not know where it leads. "Crepuscule": Slashes the boundary between worlds, dropping a "different world" onto the current one. Simply put, it is a massive meteorite and a literal "sure-kill" move. It can be destroyed if hit with an attack powerful enough to break a world. Immediately after using this, Raven is exhausted and unable to move, providing the only chance to defeat him or reach out to him.
