"He did not have to put his guards up around me."
Oumu said those words as he looked at Lucifer.
And what he said was the truth. The Blood Guardian did not have to be wary around Oumu since Oumu is literally like an ant when compared to a creature like the Blood Guardian.
Of course, this does not really mean that Oumu is as weak as an ant or anything of the sort.
There is a reason why Oumu is in charge of the Warmester Denoble House's war department and that is because he is strong as hell.
However, when compared to such a special creature like the Blood Guardian, Oumu is nothing at all.
That was why the Blood Guardian did not have to be wary or suspicious of Oumu since the Blood Guardian can end Oumu's life if he felt like it.
Of course, Lucifer knew that as well since the Blood Guardian's strength is as close to Lucifer as it can be since Lucifer gave him the right to be able to use his powers.
