Burial
You brought flowers to place on top of the place where a yakuza took a spoon and killed twenty people, and there is now a burial happening. You carefully toss the flowers in with the dirt and everything is buried together.
This is the biggest burial you've ever seen. The hole is huge. It has to fit twenty people, after all, and the spoon didn't cut them up to make things any easier.
そう
ほうむ
None
Once the burial is complete the souls (そう) of all the dead people come floating up and out of the ground. "Thaaannk YooOoOO~" they moan, as they ascend to the sky.
I guess the twenty souls couldn't go up to... wherever... until they had a proper burial.
