[Crossover] The God of Sports Drives Me to Despair

My name is Fukuzawa Xi. One day, as I was walking along, I was struck by a glowing spherical object. When I woke up, there was a System in my head. Just as I thought I was about to reach the peak of my life and embark on a path of being wildly cool, domineering, and rich, it gave me my first mission:

[Keep the ball up 100 times]

[Failure penalty: The Host's father loses half his hair]

...What did my dad ever do to deserve this?

From then on, I began going around picking fights with all kinds of sports clubs.

Note:

1. Yes, the professional plot-hole digger is acting up again.

2. Inspiration struck when I was physically exhausted from working.

3. This won't be published as a paid book. I'm writing for fun, updates whenever. Enter at your own risk.
