The Healer Leads A Double Life (As A Shapeshifting Demoness!)

Charlie is a student in modern times, studying to become a scientist. Like most ISEKAI self-inserts he's pretty lonely and washed-out. But he is determined to no longer waste his life! He's going to do something with his life god dammit. He's going to find out what his life means and he's not going to let anyone on Heaven or Earth stand in his way. But when he slips off a bridge trying to catch someone else, his ambitions are suddenly cut short. And it turns out that the goddess in charge of his reincarnation doesn't appreciate blasphemers...

He manages to escape from eternal damnation with the assistance of a mysterious patron. But can he balance his patron's demands with his desires to explore the new world before him? In a (lewd) world of magic (and might), Charlie will realise that his unexpected demise left more problems unresolved than he thought.
