The Art of Death
Two friends, Tsuki Raito, a "Yoru no Ko", and Taiyō Kurai, a "Sora no Ko", find out they are descendants of "Seirei no Hōchō". One day, tragedy strikes when the "Hātokirā" strike. Raito and Kurai decide to fight, and in doing so, become "Seirei no Hōchō".
Seven years pass since that fateful day, and Raito has become a "Yoru no Senshi" and Kurai has become a "Sora no Senshi". Whilst walking down the "Rei Michi", Kurai senses someone nearby. Raito gooes into a defensive stance, but Kurai dissapeared.
Join Tsuki Raito on a journey throught the land of Seichō, to find Taiyō Kurai again.
