Mitou Shoukan://Blood-Sign - Volume 3, Prologue

Chen Rui, an otaku from earth, is reborn into a human body in another world, who falls into the legendary evil, brutal world of the devil called Mozu where humans are treated as food. He has to survive while facing horrors of the devil, violent dragons and a variety of powerful enemies by depending on a strange super system chip and his wits. Surrounded by Devil’s beauties such as black-bellied lolita princess, cold queens, violent dragons, charming poisonous devils …

Wanting to live in the Devil’s world is hard! Wanting to live in the Devil’s world as a human is harder! Wanting a human to be the devil’s son-in-law is hardest!

Let us see how a small otaku uses power and strategy step by step starting from an ordinary human to writing a legend as the devil’s greatest son-in-law.

He is an undead who is devoid of all humanity, he is the one and only supreme overlord, he is a man who has severe mysophobia.

As tragedy befalls Xin Siyue, she soon finds herself transmigrated into a novel world as a character. To her disappointment, she became the villainess who obsessively chased after the male protagonist while scheming to tear apart his relationship with his beloved.

To avoid her death route, Xin Siyue carefully avoided the male and female protagonists at every turn. Instead, she went off on her own to enjoy life. But somewhere along the way, she made a mistake– the male protagonist took notice of her!

Xin Siyue’s eyes teared up as she was being kissed in Chen Sinan’s arms. ‘No! This wasn’t in the plot!’

Yi Ti resented her name. From an early age, she couldn’t get away from the nicknames “ET” and “alien”.

But no one thought that one day, she would actually meet an alien.

Scared by the other, it seemed like she screamed……

She fainted, then fell face down or something like that……

She seemed to have gotten a bloody nose from being knocked out……

She doesn’t remember any of this!!!

The only thing she cares about is that after she fainted, the alien actually dragged her, chest down, back home – does the alien not feel ashamed?!
