"DEATH" APPROACHES Miyama Kaito has grown quite accustomed to his new life in another world and is even rapidly expanding his harem group of friends. Not only that, but as his magical aptitude also continues to grow, he attracts the attention of more of Symphonia's odd yet powerful players. As this collection of kings and goddesses increases, Kaito's unknowingly about to encounter the most ruthless one yet. Faced with a presence heavy enough to kill, Kaito must earn the Death King's regard-or perish!
