Service
Duty
You loiter around with a weapon because you're currently doing your service and duty to your country. You're standing guard outside, waiting just in case something will happen.
やく
None
None
You're about halfway through your service, when a yak (やく) walks by. It stops directly in front of you and grunts. "Excuse me, Mr. Yak, but it's my duty to escort you away from my country."
