A family car is slowly progressing down a winding road, the famous landmark known as Mt. Fuji can be seen.
"Look girls! That's Mount Fuji outside the window."
"Whoa! Sister look! It's so tall and it's shining! So cool!"
"..."
"Come on Misaki, at least stop ogling at your phone so much! It's unhealthy."
"Sigh. Fine mom."
The girl turns off her phone and stuffs it in her pocket before looking out of the window, probably contemplating life.
The car stops at a road crossing, where no other vehicles can be seen, the car accelerates and makes a right turn, just to be hit by an incoming truck, seemingly out of nowhere.
Crash
"... Help! Please!..."
"..S-Stop! What are you doing!?.."
"...Argh!..."
