In a world layered with realms of infinite possibilities, a young boy named Kai Sotshi endures a life of hardship and abandonment. At just 12 years old, Kai has suffered immensely — subjected to a cruel father’s abuse and a mother’s cold isolation, leaving him scarred and alone. However, fate intervenes when he is taken in by compassionate foster parents, Ms. Amaiya and Mr. Tanachi, who offer him a glimmer of hope and the warmth of a real family. One day, while wandering alone through an ancient forest, Kai discovers a mysterious mask imbued with unimaginable power. This “Anti-God Mask” grants him abilities that extend far beyond human comprehension, but he can only access its full potential instinctively, triggered by moments of life-threatening peril. As he dons the mask, he was teleported to an entire different dimensional world that lacks normal humans and humans with supernatural abilities and that’s how Kai’s journey begins — a path that will lead him to transcend the limits of mortality and explore the depths of cosmic might. As Kai navigates his complex life, he faces opposition from numerous foes, including his own biological parents, who harbor dark secrets about his origins. Kai must confront both earthly and supernatural enemies, including dangerous bullies and formidable delinquents to entities in the cosmos who are higher threats with his allies yoza, joji and zon who are deuteragonists and tritagonists. Kai’s journey spans several arcs Through these escalating conflicts, Kai’s powers evolve, taking him from an ordinary human to a being with abilities that bend reality, warp time, and manipulate dimensions. From mystical red eyes that glow with power to a body capable of transcending dimensions, each transformation unlocks new abilities and brings Kai closer to becoming Omnipotent But as he ascends, he faces the ultimate question: Can he remain true to himself, or will he be consumed by the god-like power he now wields? The Parallel Realm is an epic tale of resilience, identity, and self-discovery, exploring how one boy’s struggle against the darkness within and around him transforms him into a symbol of hope — or an avatar of devastation — for the entire cosmos. warning even though I just got started on this series and is in work in progress: some volumes could contain 40 up to 100 chapters or more since it’s only 4 volumes but like I said I won’t rush through these chapters and volumes because it could be boring to some readers, I might fuse some chapters together to make it more entertaining
