Can I?

Let us turn this all around. 

"What are you doing?"

"I do not know."

"What do we do?"

"...Focus on the others. Hitori-san will take him. He does not look like a threat."

Akira clenched his fist. The scientist guy jumped and swung another punch at Hitori. Then he pulled his gun forward. 

Hitori created a shield, and the gun's head banged against it. Then he pulled the trigger. The shock and jerk Hitori felt due to the bullets made his forearm hurt. He jerked his arm and tried to push him away.

"Who the devil are you?"

"How arrogant can you be?" he said, glaring down at Hitori. He pulled back his gun and changed his target to Hitori's abdomen. 

Hitori clicked his tongue. "I am not here for that bullshit. I can not waste my time with someone I do not even know!"
