Worry

Unlike what Ichika and Erika thought, Fade found entering and exiting the building without arousing the suspicion of the Grandmaster turned out to be quite the hassle.

To Fade the so-called Grandmasters were extremely similar to the knight commanders of his old world, and with his current strength he had some confidence in fighting a rank one or two Grandmaster, as for hiding his presence he was even more confident. 

Fade thought that going in and out even with a Grandmaster watching would not be that hard, but today when he tried he found out that the Grandmaster on guard had some extraordinary senses even among the few Grandmasters he has seen in this world. This Grandmaster seems to be at rank one but he specialized in scouting which made it harder to sneak in without Fade being detected by the other party.
