Mission in wave by (female)haku

During Naruto's train while his team protected their client he passed out in the middle of a field which is where haku finds a sleeping Naruto. Haku who remembered seeing Naruto in their last battle decided this was the perfect moment to get what she wanted. Pulling out a storage scroll she gets out a collar with a obedience seal in the inside so only the person that the seals chakra is attuned to can take it off and who ever wears it will have to do what ever the owner says.
