The yard is overgrown with weeds, roughly knee-high. He bends down, parts the grass, and searches back and forth for a while, but finds nothing, nor does he smell anything unusual.
The only evidence that could prove Nishino Fuyu once fired a crossbow arrow might be the window in the front yard, with a piece of glass broken at the bottom right corner.
Fushimi Roku follows the angle of the broken glass in his mind to reconstruct the incident. If Nishino Fuyu was lying on the windowsill firing the arrow into the yard, she would likely hit an adult's private parts—if she raised the crossbow, the window glass wouldn't just shatter a small piece.
In other words, from this angle, there's no way to hit an adult's head.
Could it be that Nishino Fuyu hit a child's head?
Fushimi Roku estimated the child's height and found it plausible. If it were a teenager standing about a meter outside the window, the crossbow would hit the head.
How grim.
