Shini Yasui Kōshaku Reijō to Shichi-nin no Kikōshi - Chapter 132: Association of Mysterious Story Collectors (part two)

After being set up and killed by her half-sister whom her ex-boyfriend had cheated with, Mu Siyin woke up one day to discover that not only was she alive, but she had traveled back in time to 2 years before her death.

Frascoia Continent… Various races like Celestials, Demons, Humans, Monsters, Elves, Dwarves, and so on occupied this continent.

Humans and the other races lived on the mainland of the continent while the Celestials and Demons lived in Heaven and Purgatory, respectively.

Within the Demons, a prodigy named Azaroth rose quickly, even by demons' standards, to the point of being dubbed a Demon God. There was only one person above him within the demons: The Great Demon Venerable, the Demons' Supreme Godfather.

Azaroth's extraordinary talent never had the chance to blossom to its full potential; a terrible calamity struck him down and he died soon after. But was this calamity just misfortune or was it hiding an opportunity for him?

Near his deathbed, he prepared for his future ascent to achieve his lofty goal.

Millions of years had passed after Demon God Azaroth's demise and now a young aristocrat called Edwin Rhodes came across a mysterious cave.

I don’t need any deep relationships. I have no desire for a girlfriend, and I only require one friend who holds any value to me. Ever since I threw out my youth for the sake of efficiency, there is one person who keeps entering the bedroom of Ooboshi Akiteru. She’s neither my little sister nor my friend. She’s nothing more than a bothersome, annoying Kouhai, as well as my friend’s little sister: Kohinata Iroha.

“Senpai, let’s go on a date~! Did you think I’d say that~?”

Rather than blood, it seems like energy drinks run through her veins. She keeps occupying my bed, and she tries her best to seduce me with whatever method she can play to her favor. She’s a girl who’s constantly annoying and obnoxious around me. Even though I’m busy all day long, she doesn’t care.

And in case you’re wondering why all these envious gazes are directed at me, it’s because Iroha is actually really popular. She’s an honor student at our school with top grades to boot, and she’s known for being kind and proper to anyone she meets.

…Hey now, why are you only so annoying when you’re around me?

The first great emperor in the world was betrayed by his confidante and perished. Millions of years later, the great emperor’s soul returned and was reborn as Ye Yan, the son-in-law who was kicked out by the Chu family with a letter of divorce, restarting the supreme journey. Open the gate of immortality, kill the Jiuzhongtian, and cast an invincible name again!
