These are new-gen manga having legendary assassins as their protagonists. Both the MCs pretty much deviate from their line of work(being an assassin) and now live entirely different lives. Their assassination skills come in handy though.
They have great action scenes and lots of comedy and lighthearted moments.
Both are enjoyable and pretty fun to read.
