Kikazaru is deaf but he overcomes his disabilities by co-operating with the other wise monkeys and communicating via sign language with them. This co-operation allowed them to escape the massacre of the desert monkeys carried out by Leeuni, Ayuni, and Eruni at Amascut's command.
He along with the other two wise monkeys are important figures in the quest Do No Evil where the player reminds them about their goddess Apmeken and they charge the player into bringing monkeys back the desert, which the player does, taking them as well.
Mizaru (見ざる), Kikazaru (聞かざる), Iwazaru (言わざる), can be translated from Japanese as "Don't see, Don't speak, Don't hear", where the word "-zaru" (猿) can also be translated to monkey (猿). The three can also be translated as "See no evil, Hear no evil, Speak no evil." The maxim, Three wise monkeys (san'en, 三猿), is Japanese in origin.
