The False-Friendship Electric Shock Ring (友好電撃環 Yūkō dengeki wa?) is a special ring from the Joketsuzoku village that was created to give women a means of self-defense by giving a powerful electric shock to whoever they shake hands with.
Manga history[]
After Mousse obtained the Lens of Invincibility, he used it against Ranma Saotome, forcing the latter to bow down and beg forgiveness from him three times in front of others. Ranma, whose pride had taken a huge hit and was burning for revenge, then issued a challenge to Mousse. However he decided to also use underhanded methods and borrowed several items from Cologne. Like the Lens of Invincibility, these were used by the weak to defend themselves, and Ranma picked out what he felt were the most despicable. One of these was the False-Friendship Electric Shock Ring, which he used first in the duel after offering to shake Mousse's hand. This signaled that he was going to also use underhanded methods during the fight, ignoring Mousse's attempts to fight fairly.
