Spirit Chronicles: Tale of the world's strongest Jaeger

They said humanity’s curiosity would be its undoing—and they were right. When researchers unearthed an ancient altar, they didn’t just awaken a secret. They opened a gate, unleashing nightmarish swarms of entomorphs. Enormous, unrelenting bugs. The world’s mightiest nations fell one by one, their weapons useless against the insectoid invaders. Just when all hope seemed lost, an unexpected source offers humanity the power to fight back. — “O holy spirit. I, Ray Foster, hereby ask you to make a contract with me and help me cleanse the world.” The cat replied, “I accept.” They felt their spirit lines merging, and the cat said, “Now, the final step. Give me a name.” Ray looked at the cat and said after a while, “Yuki.” — They called him a failure. “Spiritless Sage.” A Jaeger in training with unmatched spirit energy, yet no spirit to bond with. Now armed with Yuki's power, Ray must rise through the ranks of Jaegers, face impossible odds, and cope with loss and betrayal. But with the entomorphs growing deadlier and secrets lurking in the shadows, their journey is just beginning. In a world on the brink of extinction, the fight for survival demands more than strength—it demands spirit.
