Kill Relics are a general term for special artifacts imbued with abnormal power, originating from tools used by real-life serial killers from the distant past. They are not limited to weapons like knives or scissors; they can be seemingly mundane items like lighters, needles, thread, or everyday household goods. Kill Relics harbor special abilities derived from the murders committed by their former owners or that person's abnormal obsessions. These abilities vary by tool, ranging from manipulating fire and the power to sever targets to causing abnormal phenomena under specific conditions. Kill Relic Academy A special academy established to protect, educate, and manage the girls who have become owners of Kill Relics. Kill Relic Rank System Kill Relics are categorized into four ranks based on their danger level and the scale of their abilities. Rank I: CRIME Kill Relics with relatively low danger and limited ability range. Many possess rudimentary abilities or require specific conditions to be met before they can exert a significant effect. Rank II: FELONY Kill Relics with clear combat capabilities that pose a threat to ordinary humans. If handled by a skilled user, they can achieve results comparable to higher ranks. Rank III: ATROCITY Kill Relics with extremely dangerous abilities that can cause wide-range effects or special phenomena. Depending on the user's skill, they have the potential to lead to major incidents involving the entire academy. Rank IV: MASSACRE Top-rank Kill Relics with extraordinary abilities. Their power cannot be measured by existing combat theories, and depending on the user's control, they may be considered a national-scale threat. Note that these ranks apply strictly to the Kill Relic itself.
