I'm Really Not a Clown with Special Skills.

Allen is a young man who is poor and sick. He is hungry and cold. He steals the magic crystal in a moment of confusion and is hunted down. On the way to escape, he was shot by a poisonous arrow again. When he was about to die, the soul from another world came through and took over this body. At the critical moment, he awakened the most powerful unique system, bound the panel of the demon clown Sacco, and became a bright and cheerful peerless thief... What old evil god?
