Whose Halo is This?

In a post-apocalyptic world where angels and demons roam freely, you, an unwitting detective with a knack for trouble, stumble upon a series of mysterious halos left scattered across the ruins of civilization. Each halo holds the essence of its former owner, a celestial being entangled in a web of celestial politics and mortal affairs. As you unravel the stories behind these halos, you uncover a grand conspiracy that could alter the balance between heaven and hell. Engage in witty dialogues, gather clues, and make choices that determine the fates of both mythical beings and the remnants of humanity. Can you identify whose halo belongs to whom before chaos erupts, or will you become a mere casualty of the heavenly mess?
