Bova Tannin is the third and youngest son of the former Dragon King Tannin and the first person to be one of Issei's subordinates.


Bova bears a resemblances similar to his father, appearing as a Western Dragon about 10 meters tall.


Bova is noted to being a ruffian for his bad attitude and has been noted not to have the same personality as his father who is well respected in the Underworld. Although Bova does show respect to certain individuals such as Issei. There are times when Bova can also get a bit emotional, such as in Volume 22 when he gets emotional over Issei's decision in their team meeting, praising him with exaggeration.

He despises being compared to his father and elder brothers due to having a sense of inferiority towards them.


Over the years, Bova has earned a bad reputation because of his bad attitude which is well known throughout the Underworld, leaving some to doubt he is actually Tannin's son. He would constantly seek out powerful opponents to fight against.
