Black butler, volume 23 - yana toboso

In the heart of London stands Sphere Music Hall, a venue that enjoys immense popularity amongst the populace.

However, the fervour with which its visitors return causes consternation in the mind of Her Majesty, Queen Victoria, who suspects the organisation of cult practices and sends Earl Ciel Phantomhive and his impeccable butler, Sebastian, to infiltrate the hall.

They are met with none other than the disgraced erstwhile prefects of Weston College and an otherworldly fortune-teller called Blavat, who takes one look at Sebastian and divines his true nature without faltering.
