SOA-09 affiliate Rule Objects are called such because they are actually all within the rules of SOA-09.
Including the investigators who joined later and were gradually alienated, from the moment they entered the orphanage, everything had already fallen into the rule space of SOA-09.
However, SOA-09 does not actively interfere with the spaces of other affiliate Rule Objects, akin to laissez-faire hunting, indifferent to whether the outcome is success or failure.
Its existence is merely to maintain the order of the orphanage.

Xu Shuo's mission was "to prevent any child from leaving the orphanage," which means that there definitely were children who had such thoughts.
