First Act 18: Unexpected Entry

"Uwah…!" 

A guard yawned heavily, stretching his back with a tired expression on his face.

"You should really pay more attention, Roly," reprimanded a man next to him, adorned in the same black uniform—a mixture of black and gold outlines with the Estelle Academy logo on the back.

"Chill out, Lomin. It's not like the boss will visit this place whenever, and besides, who would have the guts to enter the dungeons when there are practically hundreds of us stationed here?" Roly responded nonchalantly.

They were both members of the official guards of Estelle Academy, responsible for its security, defense, and safety. Known as Estelle Academy's guardian knights, or the 'black units,' they were led and managed by Klaus Heinrich. 

Once a famous warrior celebrated for his strength and valor in his adventurer days, Klaus had chosen to retire and dedicate himself to guarding Estelle Academy.
