Vance

Vance is the responsible and the nerd of the brothers... He is also a perfectionist

The V Brothers are the imps who work under The Detective. They were sent to foreign places, so they could note the folks who live there and collect information. 

When they are off schedule, V brothers split looking for new folks to discover. Vum was going to investigate alone,Vance and Vopqial went off together.

After The Detectives Exposure, They were jobless again. But Detectives partner, Taka, was warming and got these three a job again. 

And Taka adopted them 

Yes he straightly a d o p t e d them 

Not only they have a job but they have a father too XD
