Companion
きょう
とも, そな
None
A leader is always together with their servant. The servant is their constant companion, always following close behind the leader, offering them hot towels and bottled water.
Once a year, when the servant wants to go home to きょうと, the leader follows. The servant isn't just there for the leader, they're companions, they support each other at all times. Even if that means heading home to きょうと to see the fam.
