Seishen Kingdom emerges in the Cradle series as a formidable vassal state under the Akura clan, initially introduced through its ambitious Underlord prince, Kiro, and his companions. The kingdom's trajectory shifts dramatically when its royal family becomes entangled in the Akura clan's selection trials for the Uncrowned King Tournament, leading to devastating losses and political upheaval. Following the deaths of key royal figures and the kingdom's subsequent subjugation, Seishen transforms from an independent power into a territory under direct Akura oversight, its surviving royalty forced to navigate new allegiances.
