They immediately ran to her, to take the sword off. Obi kicked the attacker, getting him as far from his mother as possible. The person flew straight to the tree. Rather, he kicked so hard that the bastard went through a few trees.
The attacker dropped down on the floor, body at weird angles. His bones were broken by the hit and he just laid there, gasping for air.
While the rest rushed to Gaia, Orion went there to make sure the attacker couldn't do any more damage. He appeared above the bastard, realizing it was Bilia.
Even after being drowned, electrocuted, and stabbed, this bastard apparently still had enough life to make one last damage.
Orion felt especially heavy. Not only did his heart clench for his mother, he also felt burdened by the responsibility.
He was one of the people in-charge of clearing up any loose ends. This was his oversight.
