I can’t leave them here, I will take care of them.

The daughter of a duke, the stuttering Maximilian, married a knight of lowly status at her father’s coercion.

Not just any vampire—but an Original, the first of their kind.Enzo, a naïve surgical nurse who has spent his life following his father’s rules, finally decides to break free and chase his own desires, including the person he truly loves.Alaric, a feared and ruthless vampire, has long been a nightmare to both his own kind and humans alike. One cold evening, he is ambushed by six vampire hunters and left for dead. But before death can claim him, a human boy stumbles upon him and offers aid. This small act of kindness stirs something deep within Alaric’s ancient heart—an obsession. Now, Enzo is his, whether he realizes it or not.

This crossing is so strange, death crossing, game crossing, etc. are probably barely acceptable, but why can you cross even if the fish tank is broken?

and actually passed through the magic tree in “OVERLORD” that is said to be able to destroy the world?

No! It is sad enough to regenerate into a plant. The protagonist, Ainz Ur Gong, the undead king, has also accepted the adventurer’s guild mission and wants to kill me!

I want to change my destiny! Live! I want to-surrender!

Ainz: Since he has accepted the job commission from the Adventurer’s Guild, deliberate failure is detrimental to the prestige of Ainz Ul Christine (the “surrender” button has been deducted)

actually died as soon as he crossed, but there is still a chance to return~ from the beginning of the magic tree to this world.

I must change my destiny this time! Live!
