Tartaglia

Contract killer, sounds creepy doesn't it?

Although Childe is not afraid, that is what he is...

How many people did he harm?

You might ask...

Oh... Only God knows, and only God knows.

When a person is born, he is given a guardian angel for his short life.

Which protects this creation throughout the person’s short life.

But... Childe became not a very good person, and heh, angels are a bit arrogant creatures, so no one would take people like our red-haired boy.

And then, to prevent a person from dying prematurely, a demon is assigned to him, who is a replacement for an angel.

He also protects, but in his own way...

You were just such a demon... Alas, you have no choice whether to take this killer or not...

Only those assigned to watch over such demons can see them...

Some guardians live in the human body; they are located in the stomach and lungs, but...

Some choose other places...

How creepy haha...

But you haven't decided yet whether to follow him like a shadow and give the redhead a nightmare

Or become a parasite protecting him...

Or you will go another way, it is up to you to decide.

Good luck to you... In this matter, be careful not to kill him prematurely...
