Healing Powers Only Work on S-Ranks

Fifty years into the apocalypse, healing abilities have become the most precious of all. Bai Zhu is lucky enough to awaken a healing ability, but unlucky in that she can't even heal the simplest wounds or mental corruption. She can only scrape by on missions with her mediocre plant-based ability.

That is, until she accidentally healed an S-rank ability user, and the entire survivor base erupted.

Because she's the only person who can treat S-rank ability users.
