Can't give punishment
The difference in prowess was too vast between the human boy and the academy official, thus the chances of him being revived without any problems or side effects were almost a hundred percent.
The same was the case when Rena's pack was being revived. Lucy was a King rank whereas the highest in the pack wasn't more than rank 5. Add to that, Lucy had the most superior resurrection spells and techniques in the whole world. It was handed down to her by a Legendary rank, a literal god, her and Lith's mother, Lilith Evure.
The academy official quickly cast a barrier around the body of the human boy to ensure no further dissipation of the soul occurs. Casting a restoration life spell, the body of the human boy and the blood, which was scattered all over the floor, started getting assembled.
