It's been one week since Sam went outside the danger zone. Currently, he is present inside the human kingdom and present inside the guest room.
As he promised them, he visited the human kingdom and the human King also organized a welcome ceremony.
Fortunately, the human King this time did not invite those many people. The human King only celebrates the welcome ceremony with his citizens.
Sam, on the other hand, had already met the queen, the old king and even Maria. Maria also came back to the Human Kingdom from the Oni Kingdom alongside him.
On the other hand, the old Oni King and Old human king are currently present inside the part of the danger zone beside the Oni Kingdom.
You must already have predicted both of them went inside that part of the danger zone because of the Dungeon.
