Blood Thralls!
These Bastards are Blood Thralls, the unfortunate souls which had been transformed by the Blood Pond. They had completely lost their mind and became an entity of which only knows how to attack when someone entered the Blood Pond.
The Blood Pond is made from the blood and other parts of the Super powerhouses that fought in this Ruin thousands of years ago. By unique nature to this Ruin, that Blood had conjured up and turned into Blood Pond.
Blood Pond is said to be a Semi Living entity due to its ability to create the Blood Thralls; they are called Vampiric Pool.
The Grimm Monster, who came to use the Blood Pool, takes the huge risk as when they are not careful enough when consuming the Blood Pool, they could be converted by it like these seven beings surrounding me.
In them One is Human, Two are monsters and last four are the Grimm Monsters, those four of them must have been consumed by it when they are trying to devour it.
