The Seven Princes of the Thousand-Year Labyrinth: Volume 2 (Manga)

The ritual for selecting the next Emperor has begun.  One after another, candidates have fallen to the trials of the ancient labyrinth, and by their deaths, secrets are revealed to those who've survived to learn them.  Ewan Juno is among this steadily shrinking party, and as the odd man out in a group gifted with diverse talen and pedigree, the greatest mystery of all may very well be him!
