Black Tea Gentleman

Black Tea Gentleman is a character from Higanbana no Saku Yoru ni.

Vice-Principal
It is said that even though he has no rank, he is in fact the right-hand man of the Headmaster which makes him the second rank and "Vice Principal" in reality. Because of this he is often called the second ranked from the shadows.

Unlike most youkai he does not seem to like killing his prey. Instead, he approaches them by offering a contract. If the person accepts then he will grant their wish in exchange for only a portion of their soul. In reality, he is only showing the person that he contracts with what they would like to believe is reality as he consumes their soul.

He's actually employed as the vice principal, and supports both the human and the youkai Headmaster.

He's usually downright coldhearted when it comes to teachers doing their job, so whenever he's at work the staff room falls as silent as death. The only time he'll show an honest smile is when he's talking about his favorite hobby, tea.

Dealing with problems before they ever reach the Headmaster's ears is his greatest virtue.
