Location: Kumogakure no Sato
Reward: 300 ryo
Mission description: Ringo should now know the complete layout of the building, have at least one key card to get inside the mansion's locked doors, and know where the hidden safe is.  Armed with this knowledge, Ringo must sneak inside, crack the safe, and get out with the necklace.
Mission details: This mission cannot be completed until after 'Loose Talk' is accomplished.  Getting past the main gate and into the building should be pretty easy, just sneak past the guards at their stations/on patrol (2 guards at the main gate, 2 guards patrolling the courtyard  in front of the mansion).  The key card is required to get into the mansion.  Once inside, Ringo needs to get to the third floor study (the door Ringo enters must be on the first floor).  Guards will be patrolling the house as well (2 on the first floor, 3 on the second, 4 on the third).  One of the four guards on the third floor will be guarding the door into the third floor study, get rid of him by any means.  Once inside, find the safe behind a painting of the Raikage and crack/break it open.  Take the necklace and get out of there.  Must have the necklace in hand by the end of the mission.  Being discovered doesn't matter unless Ringo loses the necklace due to the discovery, see next mission.  Note: 13 total guards.
