Incident Solved
Kyoya didn't plan to let his son hunt the beasts with his small hands.
That was why the first thing he did was give him quests for bow proficiency. The husband used his All Creation System's first feature, the game system, for his son and daughter.
Kuro learned the bow proficiency in the blink of an eye and his arrows were both sharp and fast.
They never faltered and accurately landed in his preys' bodies!
"I did it, father!" Kuro let his bow go, then went to hug his father, which was a childish reaction Kyoya couldn't rebuke him at all.
As he stroked his son's black hair, Kyoya said, "Don't let the bow go, even if you want to cheer… I don't want you to develop some weird habits."
Kyoya said, but his son just raised his eyes and smiled broadly, "Father is with me, so nothing bad will happen!" He laughed and laughed, but Kyoya suddenly disappeared.
