A demon king has appeared in a neighboring kingdom and the king has to figure out how to deal with it. Meanwhile, Saitou makes a mistake which sets off a trap that sends him to one of the lower levels of the dungeon.
They're all treasures 
that I will never give up
Nein, ich behalte sie für immer
als Schatz in meinem Herzen.
São tesouros de que eu nunca vou abrir mão
Для меня это сокровища,
от которых я не откажусь.
