Belphegor  

Bel, Prince the Ripper, ベルフェゴール

The youngest member and prince of the Varia clan, Belphegor possesses the Ring of Storm and has fought Gokudera for it. He goes by the nickname "Prince the Ripper." At eight years old, he committed a horrific act of murdering his twin brother as well as his entire family. The sight of his own blood brings him immense pleasure, reminding him of the moment when he stabbed his brother. Despite this tragic past, Belphegor joined the Varia Assassination Squad on his own accord. In Christian tradition, Belphegor is associated with the sin of Sloth since he represents the idea of being lazy and indolent.
