Although Giralda directly mentioned the names of the Four Dark Monarchs, Niusel did not want to take him directly to the three players.
It wasn't that he wanted to charge a fee or deliberately make things difficult…
It was the common and necessary vigilance of the Underworld inhabitants.
While he didn't look like any kind of assassin or spy, and indeed seemed to be an important person; this "Giralda" also wasn't without his flaws and contradictions.
What if he wasn't the leader of the Four Dark Monarchs but an enemy instead?
If I were to take him directly to the Four Dark Monarchs, wouldn't I be selling them out?
Compared to the secretive Eye of the Secret that "will" change the Underworld in the future, the three of the Four Dark Monarchs have already given so much to the Sporogenesis Mill… even their souls and lives.
If for the sake of getting more help, I put aside those who have given much and helped with all their strength, then it is undoubtedly a shameful betrayal.
