Yefu

is an Anouki in. He lives in Anouki Village in the Snow Realm, with his house being located in the southwest portion of the village.

Biography
When Link visits the village, he is tasked by the Anouki chief to pair up all of the Anouki in order to put together a village watch for all the monsters that have begun to appear after the Spirit Tracks vanished. Since all Anoukis have strict requirements as to who they will pair up with, the young hero must talk to all of them and find out their preferences. Yefu comments to Link that his partner must be agile in the field, so he does not like Anoukis who have big, flashy horns. As such, Link must pair him up with Honcho, the village chief himself, who turns out to be the only Anouki who fulfills his requirement.

Trivia

 * He humorously claims that because of the fact that he and the other Anoukis are forming "Elite Teams" he took the code name "Agent Yellow".
