[#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.

Arthur still remembered the time when Ivy had said that his mana resonance would be in the single digits, and seeing a resonance of 92 from Firiel, he had started to feel numb now, as she was a genius.


'The maximum resonance should be 100, I believe.'


Arthur knew what he needed first—he needed that Mana Resonance she had. He didn't know if he would be considered a genius after getting that or not, as he could only get one other thing besides it, so he had to choose carefully.


But first, I don't know how to get her Mana Resonance.


He did believe it would be through talent or affinity at first, thinking something like mana affinity.


But after seeing all her affinities himself, he knew affinity was not the answer. He remembered in her talent there was an SS-ranked talent called Mana Genius. He believed it could be the reason for her high resonance.
