*Author Advice
-you can skip it If you wanted because it was explaining some boring stuff into his past but I recommend to read it.
He was happy now that he is free from his parent grasp and can do anything that he can't do when he is in under he parents watch but he have to be careful because her face is still same and can't do anything because he didn't want to because there are answers even though quite risky as long he mainted his face but the truth he is quite afraid of pain because of that he always careful when going outside and always wearing a black jacket and happy face mascara covering into her half face and if you look carefully you can only saw her 'black' eyes like her parents.
He is free from his parent grasp for around 5 years he is still happy but quite sad because he can't just casually saw his parent and only saw at internet news. Because the technology advanced by large margin the internet to and it became popular at mid-class and only few poor people bought it because of interest but it was still huge improvement even for humans.
He became 21 and he is quite depress because he can't talk casually to anyone else and have to wear mask and he change his mascara into black facemask with a cap into her head and always wear hoodie in case of emergency.
The one thing he can say interesting that happens into her in five years is that in almost 1 year he was almost got robbed but he fought barely and almost died. Since then he spend sometime at gym but not all time maybe weekly 4 hours gym he is quite addicted gaining muscle but it was not easy so he take easy path and not taking everyday at the gym and not buying a powder that can help her growth but he didn't do it because he didn't want to be muscle head without thinking after now 5 years it was worth it though he have 6 pack of abbs and it looked like a Greek God at the ancient times and he practiced basic self defense not fake self defense it was military low basic techniques that he got teached by retired soldier military and he has a position to he was captain of one squad and he even bragged about it but didn't talk about her experience at war and he didn't ask it too because he knew it probably sad story and he just teach me by paying her. around 1 month after he knew basic training self defense and he was teached basic footwork so you won't lost control your balance when fighting.
He love reading books novels so that's why he spend more time reading a novels than going to than gym, he constantly thinking what if he got reincarnated into another world what will happens? Will he be a hero' As he spend more time reading a book he constantly asking why hero in the novels always gets what they wanted and even though they have assh*le personality like they always said like 'im not gonna be a monsters that kill a life without emotion ' then proceeded killing a monsters without thinking even their own kind humans they are killing them as if nothing and saying like 'they deserve it' 'it was your all fault not mine for killing you' when the 'hero' constantly offends anyone and saying 'it was their fault' blah blah blah... And they only show emotion when 'hero' friends,family got hurted saying all nonsense when he totally offends anyone and saying they are monsters and he is the right one 'hero' are totally are assh*le i really hate reading novel that have title like 'hero of whatever'.
As the time passed when he totally got enraged about hero novels he stopped reading novels and find another novel that suit his personality and after constantly finding a book he finally find a best genre for her and that was 'Villain ' novels there are true villain novels but sometimes he was totally enraged because this is like hero novel but with villain title. Villain doesn't mean that you are villain you have to be a villain not just title you have to scheme that can help you to reach into top and not getting or picking harem girls because they are just pretty. he totally love 'villain ' novel even now he didn't get tired reading it only hate it when there aren't no more novel that can fit into your personality.
7 years passed when he escaped grasp at his parents. He started up a company that focus into technology he started into 500,000$ network that only money he had when he leaves at her parents house and of course he spend money at 5 years like almost 1 million dollars so he can eat 3 times a day to eat and into his house he spend 200,000. He knows it won't last long forever the money he has so he has no choice but to start company at the age 22 her company that focuses first into quality of 'gadgets ' because of lack of funds and he started to sell her hardworked creating gadgets at 1 years and they are just 5 people because of lack of funds and he have to pay her employees so they can work and after that he sell it into bigger company that about 'technology ' and got 3.1 million dollars for gadgets and that means he has no right to say that he is the owner of the gadgets that 6 of people help to create the gadgets and even they they are the creators as long it was buyer condition.
now he has high amount of money and he can now totally quit at job and as long you spend it rightly and not spending into stupid expensive brand bag or useless brand type of product and he give his employees 50k dollars each of them so that mean he has only 2.850m dollars and he came back home and reading 'villain' novels and sometimes when he was bored about 'villain' he will go into another type of genre like fantasy, western fantasy and mythology novels even bloody type novels or dark novels not just it was dark novel it was about murdering, butchering even demons eating human but he is not angry about demon because he know that it was story to even though it happen what can he do? it didn't affect her so yeah most people don't care stuff like that even though they cared it but didn't show it.
Walking in the night while wearing black face mask and black hoodie while reading novels at the phone he is focused on phone reading novels and while on her left hand is carrying a plastic bag that has coke, 2 cup noodle and some snacks with bored look as if he is depressed guys and even her handsomeness lost now because her eyes totally look like depressed and not getting sleep.
While walking into corner of the street he heard walking at her front and he look at the person who disturb at reading novel he has black jacket and tattoo on her face with quite muscle but cannot compare into her it was hidden because of her hoodie, He have a knife in his hand while pointing lower at my direction and saying "GIVE ME ALL YOUR MONEY OR YOU WANTED TO DIE!" He put his phone in the ground and her wallet throwing at the direction of thief "THATS RIGHT YOU G*Y YOU F*CK OFF " with a humiliating face as if he met a coward person in her all life. He crouched to get money that throw and he run towards into Thief but he didn't expect that the thief didn't panic instead show a smile saying "I don't want to do this this is your fault " the thief put his hand into her back and showing a pistol that already reloaded but before I can say anything the thief pointed gun into me and BANG! I was dead before knowing he died..
And that's how he got isekai as a demon .
