[#Warning Yandere]

Arthur, a 24-year-old man, was living his life normally on Earth, but until one day, on one of the most important days of his life, he died under some unexpected circumstances.  

But this was not the end as Arthur had expected, as he was reincarnated in the body of a 17-year-old handsome young man. However, the world he was reincarnated into was not a normal one, as things like magic, which he had read about in novels and manga, were common in this world.  

Yet this was not the most surprising thing he found out, as the people living in this world had reverse gender morality.  

Arthur didn't get a cheat like those protagonists in the novels he had read. However, due to his greedy personality, he unexpectedly found himself as the owner of one of the greatest treasures of the cosmos, which didn’t tell him anything other than showing a strange riddle.  

[You have become the owner of Ethelarion Replisis]  

[Name: Arthur]  

#Ability: I am the shadow that walks with you,  
               Not quite the same but near and true.  
               Half the strength but have many faces,  
               Absorb me to reclaim your grace.

Five years ago, when Mana first came to this world through a portal that opened due to foolish nuclear testing by some power-hungry country, but that was not the only thing that came as terrifying monsters also arrived with it.  

On the brink of their last hope being lost, by some miracle, another portal opened, through which a single female elf came, who wiped out these terrifying monsters in only half an hour. However, it didn’t stop there, as now Elves rule the magical Earth, and against absolute power, no one stood against her.

"I don't know how, but I know about it, master, and also know how to do it. I just have to become one with the master."


'Become one with me, huh? It does sound wrong, but I know it shouldn't be what I am thinking of.'


He knew she would cease to exist after the Genetic Assimilation, so there was something different in the mind of the crimson-haired beauty, Ember, in front of him.


He felt relieved she knew about it, as he didn't know how it would work. However, now comes the most important question.


"Ember, I have decided to assimilate with you. How do you feel knowing that your existence will end afterward?"


Ember heard what her master had said. Even knowing she would cease to exist, she didn't feel sad. She felt it was her duty to help her master, follow every one of his wishes. Knowing assimilating with him would help him in his journey, and she would also become a part of him.
