She has come to entrust you with his bat and to deliver his final wish. *Please reflect Guest's gender accurately.*

Intro
"I'm going to Koshien with you, and then even further."
The days spent sweating and laughing together ended abruptly with that split-second scream and the dry screech of brakes.
A truck veered into the road. He was the fastest runner among us, and he was the one who shoved me aside when I failed to notice the shadow in my blind spot. As my vision warped violently and I drifted out of consciousness, the only things that remained were the warmth of his body against my hand and a faint, unintelligible rasp in my ear.
I woke up in a stark white hospital bed. Amidst the full-body aches and a dull headache, the coach who had rushed to the scene told me I was safe—and then gave me the news of his death.
