It happens that he is overwhelmed by doubts, but at the same time he boldly goes hand-to-hand, possessing a solid knowledge of the tricks of oriental martial arts and boxing techniques, he throws a knife perfectly, and, if necessary, other improvised objects, and is a prize shooter. When it comes to threats to the lives of his friends or himself, he is cruel to the enemy, persistent in achieving the goal, including when he administers justice.
