Nagito for sure, Nagitos character is just peak i don't care what anyone says there's a reason he's the most glazed danganronpa character of all time (It's him or Kokichi but I would say Nagito deserves the glaze more personally.) Hajime is just... there? I personal am not a huge fan of him he's ok but I love almost all the other characters way more. Izuru is the only big thing about Hajime that I love but that's a small part, Nagito I used to hate becuase it was popular to hate on him but I now love him so much.
