[The other story has me stuck, so I'm starting a short, mindless wish-fulfillment story to get my groove back.]
After a tiring day as a corporate drone, Kamisawa Kiyoshi returns home and finds an unfamiliar app on his phone.
[Koshien Simulator]
Is this some new game?
Well, he's got nothing better to do, so Kamisawa Kiyoshi opens it.
It looks like a baseball game. Anyway, first things first: max out his stats.

Notes
1. The author knows nothing about baseball and is just making things up, so please ignore any errors.
2. Each playthrough has a different setting, and the timeline will jump around.
3. I'll refer to some real-life Japanese high school baseball history, and I'll also take liberties with reality, but I won't use specific schools or people. Sorry in advance!
4. This is pure wish fulfillment, with plenty of exaggerated descriptions and made-up records. Sorry in advance for that, too!
5. Lots of female and male characters will have one-sided crushes on the protagonist, but the protagonist won't know about them or return their feelings, so everyone's happy.
