Kasi just looked into the Giant's eyes coldly.
He could see his soul literally squeezing out of his body as the giant choked himself with his own hands.
As for the attacks that are falling on him from all sides, they are not even leaving a scratch. For that to happen, they have to go past the very thin invisible energy armor that Kasi created around his body.
As everyone watched, the Giant who struggled to control his own hands died just like that. His body fell limp and Kasi let it fall, while he captured the soul leaving his body and compressed into a very small orb before throwing it into a ring on his other finger.
He then looked at the remaining Giants that are attacking him. They all came back to their senses and when they saw his eyes, they felt like they are against a creature that they shouldn't even think of opposing.
Also they finally their attention fell on the rest of the students.
