My Pet Is a Holy Maiden

Yamagata Tatsumi and his family were traveling in their car when a wild truck smashed into their car. But wait! The MC wasn’t dead yet, his entire family was though. With his entire family dead and relatives abandoning him, the only one remaining by his side was his pet cockatiel. For a year he lived only with his pet, who had been with him since childhood. But finally, her lifespan reached its end and she died in his arms.
