Yuri, a self-proclaimed recluse, whiles away his days immersed in the digital realm until an unexpected turn of events transports him from his mundane life in Japan to the enchanting Shiyalta Kingdom. In this new world, he discovers the familial love, cozy abode, and promising prospects he had long yearned for, now immersed in the art of breeding and nurturing birds on his father's ranch. The realm, established after the downfall of a majestic empire, has thrived in peace and prosperity for ages, safeguarded by amiable neighboring nations. Although war seems a distant concern, limited to the occasional departure of Shiyalta's noble warriors astride enormous avians trained by Yuri's father and others, a sinister presence lurks within the core of the kingdom. Even Yuri, with his astute intellect, can perceive that the tranquility masking the land is ephemeral, with looming shadows hinting at an impending disruption to the kingdom's idyllic peace.
