Franca's heart churned with the vague description of the Demon's Child contained in the execution order issued by the Place—
Demon's Child
Number: Unknown
Abilities: Unknown
Features: Of suspicious origin with no definite source, their actions are unpredictable and hard to summarize into patterns, their moods are fickle and their strategies may change at any time, they have a thin regard for rules and regulations, and occasionally speak in "gibberish" incomprehensible to others during conversations; moreover, they grow extremely fast.
This ambiguous description undoubtedly made it especially difficult to judge the target.
Origin, behavior style, temperament, awareness of the law... none of these were enough to definitively determine whether someone was a Demon's Child.
After all, even without the Demon's Child, most people in today's city would fit this description.
