The mysterious 'Vanishing' takes people from across the globe, and Kaito finds himself swallowed by this mysterious phenomenon as well. Suddenly, he's transported to a remote Gurukul nestled high in the serene mountains, a stark contrast to the bustling city life he once knew. Amidst stunning nature, he seeks wisdom, makes friends, and trains under the sage of the gurukul as a disciple. The primary goal of each disciple -  to mediate in conflicts, help civilians, and represent their best interests to their rulers with their own vested interests. As war looms between the two superpowers of the world, Kaito realizes he's more than a bystander. Countless lives depend on him. Then, a greater catastrophe unfolds and rifts start to open one by one connecting to other worlds. With the invaders from the rifts now joining the fray, what was once a struggle for territories within our world spirals into cataclysmic inter-world warfare, and each realm fights relentlessly for dominance and for their own place in the world. Kaito faces a moral dilemma: peace through mutual understanding and dialogue or an overwhelming power to end strife? Ironic. In this inter-world war, just how much and how long can Kaito hold onto his newfound spiritual beliefs?   Kaito's journey transforms from one of self-discovery into a battle for survival, testing his courage, friendships, and determination.  Warning: 1.
