Same, they must have S+ level of patience and child rearing skills to be able to keep these crazy children in check. One of them throws a tantrum and someone gets sent to the hospital.
Spoiler . . . . . . . . . . . . . Iirc the guide before was a S class guide and they were seme's cousin or half brother? They were also the partner/lover of one of the espers in the team. (If Im gonna bet it was the esper who lost his temper lol)
I wonder who was able to manhandle these boys before
