I Accidentally Became A Superstar - Chapter 276: Sour Coffee

After dying in an oddly anticlimactic vending machine accident, Kazuki Ren is reincarnated in the demon realm—not as a hero, not as a villain, but as the only human male student enrolled at the mysterious Academy of Ruin, a school where all the professors are demon lords and all the students are powerful, beautiful she-demons.Ren is told he has one task: survive.But there’s a catch. The Academy’s darkest secret is about to awaken, and Ren holds a hidden power that could either destroy the demon world... or rule it.Now surrounded by seductive demons with hidden motives, eldritch tomes, forbidden dungeons, and twisted exams, Ren must master his ability—or be consumed.Magic, mystery, danger, and temptation await in this dark academia harem fantasy.

There are three realms in the multi verse; The Cosmic, the Mortal and the Nether realm.

Hal grew up in the mortal realm with no idea whatsoever of who his parents were.

His love for relics, adventure and the occasional danger would aid him in finding a genie's lamp.

Rubbing a genie's lamp should grant three wishes, but Hal is struck by lightening instead and eventually arrives in the Cosmic realm with a large book in his mind space titled; The Primordial Cosmic Grimiore, that apparently holds all knowledge for a perpetual reign.

And so Hal's journey begins in a little city called Salmon city, in the body of a 17 year old boy also named Hal but was sold into slavery by his own father.

Hal finds out who his mother (prior to reincarnation) whose bloodline now flows unmixed in his new body is....

Join Hal as he battles mortals, Dragons, phoenixes, Gods and many more together with his harem of Beauties for the complete subjugation of the three realms.

Passerby-A is increasingly dissatisfied with their small part in the drama. By chance, Luo Ran was born because of this one sentiment. Her purpose is only one – to add scenes!

If you want to add scenes, you have to be with people who have more scenes. And those who have the most, are the male lead!

In the imperial harem, she is the second-class maid-in-waiting who died early beside the female lead.

In the immortal world, she is a flower demon who was mistakenly killed by the female lead before she was transformed.

In the CEO world, she is the smart secretary of the President.

In the entertainment world, she is a singer who has nothing to do with the male lead.

Luo ran uses these identities to attack the male lead and fulfill the desires of passers-by A; to add more scenes!

TN:

Passerby-A = Anonymous person, someone unimportant with a tiny role.
Add scene = to add value to a role with more scenes.
