Fixten

After Stargaze Family executed his family, Noel Ardagan embarked on his journey, restoring his family name with the help of a System. 

"What? How the heck did she get it before me? The system told me that I'm the only one who knows about it!" Noel Ardagan cursed in anger, "That conniving murdering woman!"

"At this point in time, only I should be aware about this tomb. But how did he find out about it?" Anna Stargaze, even after her reincarnation, couldn’t comprehend Noel's actions.

The clash between of a person holding a system and a reincarnator who knows everything in the future is about to start.

System vs Rebirth

"This is…" Noel's expression turned grim when he was looking at the airport.

"We have been hunting here for two days. Tomorrow will be the third day, and Dimitri should be arriving somewhere in the evening." Noel crossed his arms as if he were bothered by something.

"Are you thinking that this has gone too well for us?" Anna asked.

"I can say it's going well, but…" Noel fell silent for a moment. "The fact that nothing happens is more concerning. Do you know what scares me the most?"

"The Demon King? Your parents?" Anna answered jokingly, trying to lighten the mood.

"No. It's the unknown." Noel shook his head helplessly. "I'd rather fight against a Demon King than an unknown. If it's a Demon King, I can prepare for its arrival at the very least. But if I have to fight the unknown… I can't help but overthink it. What is their strength? How much people they have? That kind of stuff."
