A Meteor Falls: I Awaken a Stand

In 2050, a massive meteorite from outer space crashed into Earth, carrying a new and unknown virus. Those infected suffered from persistent high fevers. Among those who woke from the fever, a tiny minority gained a mysterious ability: a Stand.

Only Stand users can see Stands, and only Stand users can defeat them.

(This novel draws on the power system from the famous anime series JoJo's Bizarre Adventure, though I've adjusted some of the settings to suit my own ideas.)
