I need your help

Everyone then looked in the direction of the voice and saw a man.

He had short gray hair and was wearing a very simple outfit. He didn't have any weapon with him, but for some reason, while looking at him everyone was feeling apprehensive.

Guna then said, "Who is-", but was interrupted by Dan, who said, "Leader! What are you doing here?!"

Hearing this, everyone was in shock for a few seconds, and then Guna said, "Wait a minute. Is this the leader of the sect?"

The gray-haired man then said, "Yes, I am the leader, but I don't like to be called that unless necessary. You can call me Mister Darko."

Upon hearing this, Guna went silent and then looked at Gen, and realized that he looked very tense.

Dan then said, "Leader, what are you doing here? Has something happened?"

And Darko said, "Why does something have to have happened for me to come here? Can't I just be walking around?"
