Since then, strange things happen and everyone accuses SO for bringing the bad luck. Their assumption is unscientific to NIN; hence, he decides to investigate. He discovers that SO is suffering from sleep-walking and creates the mystery instead. Apart, YUI tends to find a fighting a cricket near the stream. He finds MEI who injures and faints by a poison snake. At the same time, a leech hurts YUI also. YUI throws the leech away quickly and it just drops at the wounds of MEI by accident. YUI runs away in a hurry and drops his jade ring.
