Massacre

The fact that the stench of death was plaguing the sewers deeply disturbed both Johan and Leon Vergil both of whom have a heightened sense of smell. But the other one who could not really mask his disgust that well when compared to the Fifth Apostle's way of doing it was Leon Vergil. Leon was visibly upset at the fact that there was the stench of blood and death reeking in the air, not just the musty smell of sewage, but the fact that it added to the overall disgust of it did not help at all, however. 

Johan did better to hide it, though. "What is wrong, Leon?" Kyro Shin asked him with a concerned look on his face as he noticed that Leon Vergil's face was more sour and had a much worse time adapting to the stench of the sewers than all the other members of the assault squad. "Nothing, it is just that this place smells so fucking bad, you cannot believe it…" He replied back as he covered his nose with his undershirt that was worn under his white armor.
