Yamagata Tatsumi and his family were traveling in their car whenever a wild truck smashed to their car. But wait! The MC wasnt dead yet, his entire family was though. Along with his entire family dead and relatives abandoning him, the only person remaining by his side was his pet cockatiel. For just a year he lived only along with his pet, who was simply with him since childhood. But finally, her lifespan reached its end and she died in his arms. After his pet died, he lost his will to reside in and spent everyday meaninglessly. But since her death, every evening he wished for a woman praying in the room manufactured from stone. 10 days passed and he reminiscences about the bird while using his classical guitar the song they used to sing together. Then suddenly the region around his bed commenced to shine, and the scenery around him changed. He was still on his bed, however the room converted into the main one from his dreams, and the lady was there. The lady was teary eyed and then jumped after and embraced him. The lady, Holy Woman Calzedonia, smiled brightly and said Finally finally we meet again, master I am your dog. Chiiko!
