--(Manabu's POV)—
'He is good.'
Manabu kept his eyes peeled to make sure none of Nathan's moves goes unnoticed.
As the tank, his job was to block all long-range attacks from Nathan.
'Maybe we can defeat him before the Captain returns!'
When they became aware of the existence of an intruder who was trying to steal the prizes, they created this plan.
Manabu will leave the building first to get out and call for reinforcements.
While Tress and Sean, the two warriors Nathan was fighting, will stay to hinder the trespasser.
The sentries Nathan fought were unaware of the plan. Tress and Sean left them as bait to gauge Nathan's combat abilities.
By roughly analyzing the time it took Nathan to defeat each group, they were sure that he wasn't Enma-rank.
'Well, the prizes aren't important enough for an Enma-rank to try robbery in Underworld.'
Fun Fact-
Nathan wasn't using [Domination Decree] at full power as-
1. It uses too much ether
2. It might alert more people
