Remember when a war erupted in Day 147? It happened between 2 other countries, slightly away from the Kirika Empire.
Lately I've been busy and because of that I disregarded them.
Anyway, the Lumen Holy Kingdom won that war. They recently began to start annoying actions behind the scenes.
The Holy Kingdom proclaimed the human supremacy doctrine, and took all territory of the conquered Erinbe Iron Forest Countries, raising its own national strength.
After that, their already vast territory, has grown even more, surpassing even the Kirika Empire, which itself is already much bigger than the Sternbild Kingdom.
Not only that, in this war, all the Legendary Heroes, Great Heroes and Heroes, who I will just call Heroes altogether, of the Erinbe Iron Forest Countries has joined ranks of the victor, bringing the total number of Heroes in the Holy Kingdom to 24 people.
In comparison with Sternbild Kingdom which only has 4 Heroes, and the 8 Heroes in the Kirika Empire, it has become clear of the extent of their current strength.
Lumen Holy Kingdom has a long and terrible relationship with the King of Beasts Lionel, who rules over the kingdom of beastmen, East Grand Beast Kingdom. Lionel is also allied with Emperor Hyulton of the Atarakua Demon Empire.
Lets just say that the Lumen Holy Kingdom can now fight them on an equal footing.
In general, if you throw out all the details, the Holy Kingdom is on the rise. Behind the scenes of all this, they began to send out even more assassins and spies into different countries, to gather information and to make incidents.
I can not say for sure, but it is likely that recently the people who attacked Minokichi were them.
Sending out low social status nobles and beastmen on dangerous missions, such as hired killings, is one of the methods of the Lumen Holy Kingdom.
At this time, it just happens that Minokichi-kun and company accidentally hit them during their quest, not wanting to put their activity in the Sternbild Kingdom in jeopardy, they decided that their enemy's numbers was not much and that it's time to eliminate witnesses.
As a result, they were divided. Whether my guess is correct or not, I do not know. As expected, the gathering of information ot such levels is impossible, even for me. If only one survived, we would know all of it immediately, but they were all wiped out.
But if this theory is correct, we would have to return the favor to them.
If out of the 24, 12 suddenly disappear,it is in fact better, I think.
