N-S Crest is a pair of gadgets that resemble badges with the letter N or S on it. It corresponds in the similar manner a magnet is for one person wearing them with another person that is also wearing them.


When two persons wears the same Crest (either N or S), they will repel each other, just like how magnets works. While if one person wears the N Crest while the other wears the S Crest, they'll be attracted to each other. Simply put, the Crest itself cause the person to become a magnetic pole themselves (theoretically speaking).
