Hi, my pick today is the Shounen Action Fantasy manga "Double Arts" about a boy and a girl are forced to join hands to resist a disease.

Description:

A boy and a girl are forced to join hands for all eternity!?
In a land ravaged by an epidemic known as "Troy", the only people with healing arts capable of stopping the seizures caused by the disease are the Sisters. Although they have a high resistance to the disease, they are searching for a person who is truly immune, so that they can find a cure. The main character is Sister Elraine, one of the Sisters who becomes infected with Troy. But, when she touches Kiri, a seemingly ordinary boy, her seizures stop. Could he be the one!?
