what happens when an ability user can swap ability's? What happens when it can effect Dazai? What happens when corruption goes with Chuuyas ability?

it was a normal mission until chuuya could no longer feel the fiery heat of tainted sorrow but the cool tone of no longer human. Before he could see... he looked at Osamu Dazai, his husband..m only to see familiar red markings covering him... nit only did dazai nulification not work... bit Dazai somehow activated Corruption!?
