Correct
There is a line on the ground so you stop, making a giant sign pop up that says CORRECT! You obeyed the rules of the road and did the correct thing. Good on you.
Imagine walking, staring at the ground until you come across a line that you're supposed to stop at. If you stop, the big "correct" sign appears, chiming a happy tune.
せい, しょう
ただ, まさ
None
You did the correct thing, so here's your reward: a saber (せい) from the Shougun (しょう) himself!
Perhaps a slightly unorthodox weapon for a ruler of medieval Japan, but you won't complain about a saber from the Shogun himself!
