Raidorl Seiken Senki - Chapter 45: The Kings Melancholy.

Eighteen-year-old Trinity is unlike any other werewolf in her pack. For one, there were unusual circumstances surrounding her birth, for another, she is the only pack member to never shift into a wolf form. So now she doesn't quite belong anywhere. Not quite human and not quite wolf.

She, the world's chief doctor of the 21st century, the legendary overlord of the medical world, was killed and her soul transmigrated…She, the useless miss of the Windcloud Empire, was ugly, silly, and obsessed! She died in her own sister and fiancé's hands…When she reopened her eyes again, she had the soul of the strong but the body of the weak…When she became her, her fate would be rewritten and a miracle would appear…This was a story of a two-faced person meeting another two-faced person. With pure hearts, they would end up together.

Reborn into the world of Yugioh, it's natural if my goal is to become the best duelist!

What would you say is the most valuable thing in this world?
