After I became the Demon King, all that was left of me was a 6k square meter area of control and a smartphone with an app called 'World Salvation Project' installed on it.

　Let's see.......what am I supposed to do?

　My room at home. I sit on my bed with my own scent seeping in and operate my smartphone.

　Is there an instruction manual...?

　I love to read the owner's manual. Some of them are like, "What?　You read that thick stuff?　Isn't that bacca?

　Pain runs through my brain.

　Huh?　

　No, I can't remember. I get a terrible headache when I try to remember.

　Is this the effect of what that girl said ... erasing the memories of all those people?

　I give up trying to remember and think about the instructions again.

　The instructions ... I wonder if there are any instructions.

　As is my usual habit, I type 'World Salvation Project' into the search bar on my smartphone.

　The search results were only articles that seemed to be related to religion.

　Hmmm. I can't find any. There are a lot of cases where the manufacturer makes PDF versions of the instructions for older machines and posts them on the net, but "World Salvation Project" doesn't seem to have any instructions.

　I don't like to operate it by feel, though....

　While complaining, I tap the "World Salvation Project" app on the screen of my smartphone.

　World Salvation Project] Start☆ First, let's know your status. [Status]

　Tap [Status].

　Name: canon.
　Appropriate: chaos.
　Race: Demon King
　LV: 1
　CP: 100
　Body: E
　Magic power: E
　Knowledge: E
　Creation: E
　Training: e
　BP: 10
　Special Ability: Demon King
　　　　　　Creation of a dominant domain
　　　　　　subordinate creation
　　　　　　Item Refinement
　　　　　　instantaneous memory

　Status?　What does it mean, social status or status?

　But that's not quite right, is it?

　Oh!　That one!　When I was in junior high school, I was short on pocket money but I really wanted to read print, so I saw it when I was scouring free web fiction sites... an alternate universe story that looked like a game world. ... uh, what was the title?　Was it Genesis Online?　It was in that novel, status.

　It's quite different from the statuses in that novel, but the perception should be correct.

　I finished looking through the statuses, so I operated my smartphone--

The Demon King's IROHA

　Nope!　Let's start by shaking BP to bolster your abilities!

　Lo!　Then create the dominant area and make it your own!

　Ha!　Finally, let's create a regiment to protect our dominion!

　We're all set!　Wage a fierce struggle and save the world!'

　A sentence appeared on the screen with a girl's voice playing in my brain.

　Was this supposed to be an instruction manual?

　Isn't that too general?　There's a bit more detail in the instructions for foreign products.

　I operate my smartphone, feeling mildly indignant.

　Then the screen shows icons labeled 【Status】, 【Dominant Area】, 【Possessions】, 【District】, 【Dominant Area Creation】, 【District Creation】, 【Item Alchemy】, 【BP Spending】, and 【Special】.

　None of the items make sense. Instructions!　Instructions, please!

　I tap the "Special" item that I saw for now.

'Special Service* I'll answer one question of any kind.

　The long awaited instruction manual ....

　One.........just one?

　I'll have the manual!　← This isn't a question, is it?

　Where are the instructions?　The answer could be 'it doesn't exist' or something like that, right?

　I'm torn. I can't just ask one question. I want to know everything.

　Asking a question halfway through will only create new questions, right?

　Hmmm... It's the "World Salvation Project".........

　Ah!?

　I have one big question.

　I operate my smart phone and type in my question..............................

　-- 'Does this world need to be saved?'

　In the first place, almost all of the causes of the destruction are human beings.

　Is it necessary to save such an unreasonable world - a world created by unreasonable humans?

　After a few moments, the answer came back on my smartphone screen.

'Marvelous!　Best question ever!　As a bonus, you will receive 10 points of BP.

　....What?

　What is this.........

　And your smartphone displays the answer to the question I posed.

'You'll have to see for yourself if this Kowaleta world needs to be saved. It's all right. Your [Chaos] proper is the best. You will be able to confirm it. And decide for yourself whether you want to save this Kowaleta world or destroy it.

　A switch in the argument?　After all, do you just keep throwing the answers at me?

　The question I posed was answered with an unreasonable answer.


　　◆


　What are we going to do in the meantime?

　Shall we follow "The Demon King's I-Ro-Ha☆" which is too childish to be called a manual?

　From my experience, in all times and places, in all times and places, it is better to follow a manual for all things. The manual is the result of wisdom and experience, and it is the result of optimal solutions.

　So, I wonder if we should allocate BP to it?

　I'm in trouble........ Which one should I allocate to?

　The body, magic, knowledge, creation, smelting. All of these seem important to me.

　For now, I wonder if it's a good idea to shake them one at a time, see what has changed, and then shake BP to the items that are meaningful?

　I assigned them, one point at a time, starting at the top.

　--?

　The status screen does not change. To be precise, one item has changed.

　BP has dropped from 20 to 15, which means it's swinging, right?

　That means the BP is swinging, right?

　I tap on the physical item again, trying to allocate one point at a time from the top in order.

　Ah!

　My BP has decreased from 15 to 14 and the physical body value has changed from E to D.

　And I feel a change in my body.

　What can I say.......lighter?　Do you feel full of energy?　At any rate, my whole body is so full of energy that I feel like I could do a lap around the schoolyard now and not run out of breath.

　Is this the change in my body?

　Then tap the magic power item.

　BP decreases from 14 to 13, and the magic power value changes from E to D. Furthermore, 【Earth Javelin】 has been added to the Special Ability column.

　........Magic?

　I've never heard the word [Earth Javelin] before. I've never used magic, of course. But somehow, instinctively I understand how to use [Earth Javelin].

　I look out the window and focus my attention on the empty street.

　Then I hold out my right hand and remind myself.

　--Earth Javelin!

　The ground at the end of my focused attention trembled and a sharp clump of earth rose up.

''Wah!?''

　When the dust cloud subsided, there were pieces of asphalt that had been cruelly destroyed scattered around.

　Is this the change in magic power?

　

　I let out a dry, self-deprecating laugh in my room.

　Let's see, now it's knowledge.

　I tap on the [Knowledge] item.

　BP decreases from 13 to 12, and the value of knowledge changes from E to D.

　--!

　I rejoice at the phenomenon that has happened to me.

　The instructions were there!

　The moment the knowledge went from E to D, countless pieces of knowledge flowed into my head.

　Not in paper form, not in electronic form, not in electronic form, but in a wild way of downloading directly into my head... but the instructions did indeed exist.

　Now I know many things.

　Like knowing that the answer to 1 + 1 is 2, like knowing that the boiling point of water is 100 degrees Celsius, like knowing that the Kamakura Shogunate was founded in 1185...........I have gained knowledge about various 'world salvation projects' as if I had learned.

　Physical status is a value that reflects arm strength, endurance, agility, and reaction. Knowledge status is a value that reflects the depth of your knowledge. Also, as your knowledge grows, you can understand the languages of many races. A slime is a rank F monster. They are the remnants of lowly demons. It can handle a dissolving liquid that can burn the skin. Strong against physics and weak against magic. To grow from E to D requires 2 BP, to grow from D to C requires 5 BP, to grow from C to B. To grow from C to B requires... what?　I don't understand this and.

　I don't understand it in places, but I've also gained knowledge about monsters I haven't seen or heard of yet, including information about monsters I've never seen or heard of.

　So, knowledge is an instruction manual?

　I seriously wonder if I should allocate all my BP to knowledge.

　I have 12 BP left, and I'm allocating 1 BP each to creation and alchemy.

　If this is the case, the BP I allocated to creation and alchemy will be wasted.

　I allocated 1 BP for creation and alchemy, and 5 BP for knowledge.

　As a result, my creation and smelting grew from E to D. My knowledge grew from D to C. I allocated 1 BP to creation and smelting and 5 BP to knowledge. My knowledge grew from D to C, and I was able to gain even more knowledge.

　With my newly acquired knowledge, I learned that the BP needed to grow from C to B was 10.

　I have 5 BP left; and the BP I can gain from moving up a level is 5.

　In other words, if I raise my level to 2, my knowledge will grow to B.

　I had found a ray of light from a situation of total darkness, where I knew nothing.

　--I didn't even know the consequences of this choice at the time.
