Shadows flashed by as Sirius came back to the battlefield. His figure was covered by shadows that seemed to flicker every second.
"Don't worry. He will be here soon," Sirius told the rest of them and raised his hands. The shadows around him surged and condensed around his claws. His claws turned deadlier as the darkness within them seemed alive.
Sirius grinned. He felt his blood boil as the urge to tear the assassin into various pieces made him forget everything else. Kicking the ground, Sirius's figure flickered as he disappeared.
The space in front of the assassin fluctuated as Sirius appeared there and slashed down at the assassin. Seeing the dangerous arc of darkness approach him, the assassin crossed his hands over his chest and blocked the attack.
"Blerghhh," The assassin suddenly coughed as blood poured out of his throat.
