My next summons that day weren't that hard to do, as after my first wish granting mission, the next one was of me being summoned in another world.
.....
Random Other World:
Soon I had arrived within the world as I took in my surroundings but before I could take a closer look suddenly someone shook my shoulders as I heard numerous screams all around me, as if a war of sorts was ongoing.
Focusing my mind I saw that I was in some area with lush greenery and the boy shaking my shoulders was of only 8 years old I assume, as around me the lush green forestry was being decimated at an unprecedented rate, with fire being the culprit and I saw a few slash and burns around me.
After this I turned to the silent boy who was angry and sad at the same time with the face of, 'Damn if only I was strong enough I could of protected my close ones, it's not fair/I'm going to dedicate my life seeking strength to gain revenge!'
And seeing the probable future of the boy I quickly turned his attention to me as I did a Beerus flick on his forehead causing him to turn to me again, seeing this his once dim blue eyes gained hope and strength, and his eyes became determined, before he said,
"I summoned you Devil-san, as I wish to gain enough strength to protect everyone around me and save my sister- the only family member I have in this world!" The boy said this with so much vindication I thought I was watching another Sasuke.
No I must not let this young child pursue Sasuke's path and become a degenerate I must help him, his young blue eyes are calling out to me- to save him from Sasugae's path.
And so I asked the silver haired and blue eyed child, "Boy, If I give you strength what will you do with it!" I said this as I was testing him, while I said this the carnage was still going on as countless Orcs ravaged-killed- and ate the humans.
The boy seeing he has not much time replied quickly, "I will save my village, I will become a hero and I will end the Demon Kings Reign, that is my Warriors way, you better believe it!" And after that he made a determined expression while pointing out his thumb forwards.
Seeing this I sighed before saying, "...Sure" and after that I did a Beerus flick again this time however I infused my Qi-Techniques and training tips to him and gave him some of my Qi to augment his physique, and so he learnt how to manipulate Qi and increased his strength rapidly turning his Battle Power of 0.2 to 15.
Meaning he could now wipe out the orcs who had each 7 Battle Power- it seems they were all low level orcs, "Boy tell me what is your name, and now what will you give me in exchange for this strength!"
I said as I tried to imitate a cliche devil from the movies, with my voice seeming tempting to say yes to anything. The boy thought for a while before saying, "-... Damn... Everyones... There.. Dying… My name is Gin- as in silver, and I will give up my-"
"Argh Help!" "GIN RUN AWAY!!!" "Quick the Orcs coming towards you!!!"
"-...Damn it- I- I give up my feelings of Love for this Power!" And after that Issei had vanished as his deal was done, but before he left he found that Gin had easily wiped out each and every Orc and prevented his precious ones from dying, and this wish of his was common but the price was uncommon.
The eight year old boy decided to give up his 'Love' meaning he will not have any distractions- things that cloud his mind, such as Love- no partner nothing like that, honestly he felt this wish was too cruel for a person to live by, as even he would need love.
And that was the last time Gin saw his saviour and Plaguer, and in the time since he had grown into a fine young man though he had no feelings towards any gender other than care for his only sister, but that was it.
He lived his whole life indifferently and the only thing that mattered within his mind was to train- train and become stronger and stronger and stronger. In the end when he was 99,947 he remembered the day he sold his soul to the devil- at that point he had killed each and every Demon King and had killed the Demon Lord at age 140, ridding the world of the demonic realm.
Having done that his whole life's mission was complete- he had nothing to do other than that, and because of his numerous killings, and crusades to rid the world of demon scum, the emperors daughter was betrothed to him, the girl immediately fell for his indifferent nature and handsome face with his shoulder length silver hair.
And soon the two were married though Gin never gave a damn about it- he had tried to love his wife and say things to her from the bottom of his heart to her- but he couldn't this damn curse for power had stopped him from it. And due to this tension rose as his wife had given up on him and left after 12 years of marriage and had an affair with one of his companions who helped him kill the Demon Lord.
When he found out about this the woman he had married tried to justify her reasons saying he never loved her kept her as a prize, that he never showed affection to her, and that Only Ningen Sukamu (Human Scum is his name) showed her affection causing her to indulge in this affair.
Having heard enough Gin began his massacre "NO ONE GIVES ME A GREEN HAT!! where his exact words as he slaughtered his ex wife in cold blood who was pregnant with his treacherous friends child, he chopped her from the chin to the navel (From Chin to Stomach straight through body) instantly killing the child growing in her.
But he didn't stop he then killed his longtime friend and even brother by chopping off his dick and pierced all of his limbs took out his intestines from his abdominals causing him to bleed out and die.
And so he completely obliterated the Clan not a single person or child born or unborn was spared from his genocide. He realised that day that regardless of him killing all the demons, that in the end Humanoty were the greatest demons of all.
And so he became the thing he despised he became the Demon Lord, the one the only "Blue Eyed Silver Haired Demon Lord Of Madness!!"
