The southern land - a swarm of more than a thousand demons invaded from Kanazawa City.

　Kanazawa City, Kahoku, Kahoku City, Hakui, Hakui, Nanao City, Kashima County, Hozu County and Wajima City have already fallen into their hands.

　They have infiltrated not only the neighboring cities, towns and villages, but also the area under the control of their own people, and continue to move northward.

''Sayama-san.......what should we do?''

　A young man who has been evacuated from Kanazawa City - a young man who is now a member of a neighborhood watch group - calls out to me with a trembling voice.

''Master we're ready to go!　Let us avenge your ... daughter!
They are our enemies!　Let's get rid of Master's disappointment!

　A group of bloodthirsty disciples began to clamor with spent swords in hand.

''But ... rumor has it that if you surrender, they'll save your life ...''
f*ck you!　Don't fall for that kind of hoax!
'Yes!　Yes!　There's no way we'll ever get along with them!
And yet when there are more than a thousand enemies...
'And they say he's far stronger than goblins and kobolds...'
"Fear not!　If we give up, who's going to protect us all ... our families!

　The opportunistic and the bloodthirsty quarrel with the opportunistic.

　The enemy is powerful. The odds are ... well, the chances of survival are slim to none. Perhaps it would be happier for you to surrender according to your own observations.

　But my mind was already made up.

Calm down!　Fools!

　A word of warning silenced the others.

''Those who can't fight, hide in the inn at the back of Pearl Harbor!　All those who can fight, rally to the city hall!　

　I give orders to those huddled together.

　The vengeance of my sons is already done. Now there is only one enemy left to avenge.

　I proceeded on the path of Shura to fulfill my vow to avenge my granddaughter.


　　◇


　The year is 20XX.

　In the countryside of Suzu City, Sayama Kotetsu operated a dojo. The dojo has produced many police officers and self-defense force members.

　The dojo has been in existence since the Edo period, and his son became a policeman. My grandson, who was called a child prodigy, followed his father's footsteps and became a policeman, and my granddaughter, who had a talent for swords but was too kind-hearted, abandoned it and went to a university in Kanazawa.

　There were about ten of her students and a group of kendo club members from the high school and college in Wajima City. Teaching them the way of the sword was my daily routine.

　The family get-togethers during New Year's and Bon holidays were my favorite times of the year, which came only twice a year.

　But my daily routine ended the day when all of humanity received an email on their smartphones.

　An impenetrable zone has appeared all over the world - a dominion territory that has taken away a great deal of land from mankind.

　Troublingly, the dominant realm occurred concentrated in urban centers. As a result, many human beings were forced to evacuate to depopulated areas.

　Many of the citizens of Kanazawa, the central city in Ishikawa Prefecture, were evacuated to Suzu City.

　Thirty days after the emergence of the dominant realm - the world was even more turbulent.

　-- "The World Salvation Project

　This is the day when the "Revelation from the Goddess" took place.
This was the day that the goddess gave me a mysterious power.

--The war between humanity and the demon king began.

　When the existence of a different life form from the human race was discovered, people from Hebei, Kahoku City, Hakui, Hakui, Hakui, Kashima County, Nanao City and Wajima City followed the lead of the citizens of Kanazawa, who had been evacuated to the city, and moved to Zhuzu City.

　With the support of the government, many of the inns in Suzu were opened to the public as temporary housing for the evacuated people, and they huddled together to live a modest life.

　Then one day...

　One young man - a young man once called a prodigy - uttered a suggestion.

'Wouldn't it be easier to transport food if we liberated the territory we control in XX town?'

　The area under the control of XX town existed in a way that blocked the Noto-Kaiban road that connected Suzu City and Wajima City.

"Liberation...!　There are demons that eat people in the realm of control!

　The mayor of Suzu City objected to the young man's suggestion.

'It's okay, was it a goblin?　That's the wolf, right?　It's a good thing.

　However, the young man waved one hand in response to the mayor's objections and gave him a spare look. Recently, there had been an increase in the number of demons flying out from some of the control realms, attacking the people in the neighborhood and destroying crops.

''But........there are other ferocious demons within the control realm.......''
You saw the news. I'll be fine.　Didn't they liberate the territory they control in Kanazawa City?
And yet...
I'm fine!　If he can do it there's no reason I can't do it, right?
Uh.... but...
Takashi!　Do you insist on going?

　A man interrupts the conversation between the confident young man and the greasy sweating mayor.

'I'm going.... You know my dad, right?　At this rate, we will run out of food. Well, it's not too late.　We have to take action while we can afford it!
Well.......... I understand. But there's one condition.
Conditions...?

　The young man's father snickers and sticks his index finger up at the bewildered young man.

'Yeah. I'm going with you. No complaints?
What?　Dad too...?
What?　I haven't lost my skills, okay?
'I know that, but.... OK. Dad I'll go with you!
'Master!　We will accompany you!

　Many of the youngsters had finished talking with their father and son and volunteered to accompany them.

　And so a young man, my grandson, who was called a child prodigy, along with his father, my son, and my pupil, began to invade the territory they controlled.


　　


　20 days later.

　The grandson, his son and his students succeeded in liberating the territory they controlled.

　They became heroes who gave hope to the people of Suzu City.

　I was so proud of my grandson and his son and his students.

　In a world that has been full of gloom since that day it was my only hope.

　But those happy days were not to last.
