I Transmigrated as the Tyrant Demon Emperor in a BL Otome Game [ BL Harem ]

Eons ago good and evil emerged in the world. The two had always clashed with each other and in the end, good would always prevail and triumphant over evil.

So, how would one define good and evil?

I transmigrated into a BL otome game at the beginning of the game as Cassius Alastor, the youngest Emperor of the Demon Realm who just turned 17 years old who was known by all as a notorious Tyrant! Emperor Cassius Alastor was also the otome game's villain otherwise known as the Final Boss who kidnaps the heroine!

Furthermore, I became the 1st Capture Target's adoptive older brother.

Unfortunately for me, Cassius already abused the poor child so much that the 1st Capture Target ran away to the human realm where he would encounter 4 Capture Targets as well as the Heroine at the Academy!

After graduation, they ban together to kill the Tyrant Demon Emperor and bring peace and prosperity to all.

Bullshit! I value my life, I must find a way to survive!

But what's this?

I somehow transmigrated with a system?

Seduce the Capture Targets System? Oh hell no! I'm straight, completely straight like a ruler!

But I have a question.

Why do these handsome men who keep popping out of nowhere make my heart beat?

Also, are these guys semes or a ukes because I'm getting both vibes from them.

It seems like along the way I gained a harem but WHY ARE THERE SO MANY OF THEM!?

1st Capture Target: "Don't be like that, it's only the 10th round."

2nd Capture Target: "Your body is begging for more."

3rd Capture Target: "Can I ride you?"

4th Capture Target: "I want to hear you scream louder."

5th Capture Target: "I don't think you'll be able to walk for at least 2 weeks."

Hidden Capture Target: "Cry more, it's sexy."

System 005: "I might be small, but I can definitely top you!"

"FOR THE LOVE OF MY SANITY LET ME HAVE A BREAK!"
