I feel like these two are essentially the same story, but with different treatments. Not a surprise, seeing how they were written by the same managaka. We have a creature with supernatural powers (tengu/sorcerer) who has an obligation/contract with our human MC, alongside a non-human supernatural side kick and a soft villain who comes from the same realm as our tengu/sorcerer
