I Became the Only Healer in This World

Synopsis

A lifelong game-addict healer with decades of experience. By chance, the world changed, and I became the only healer in existence. [A place that needs you, the one and only healer, has summoned you.]

[Will you accept the summons?] "What? They have tanks and DPS but no healer?" Seriously, what kind of broken game balance is this?

[The constellations observing you protest indignantly: "This isn’t a game—it’s reality!"] Decades have passed since the Gates first appeared. I’d heard they’d accumulated plenty of strategies and data by now, but— "Why is everyone so inefficient? It’s infuriating."

As someone obsessed with optimal strategies, I focused solely on obliterating the Gates. But then— "You’re the one who saved me. You made it so I can’t see anyone but you." — A betrayed former No. 1 ranker who became a recluse: "I need you. My savior. My life." —The leader of the world’s top 10 guild alliance: "Don’t abandon me. I can’t even breathe without you." —The current No. 1 ranker: "I’m already drowning in Gate raids, but now these strange people won’t leave me alone."
