Can somebody tell me where the line "as expected of my sworn friend" originally comes from? Kinda like how "I'm not a bad slime" came from Dragon Quest, I'd like to know what this reference is.
@wizardsonly Rimuru wasn't talking about the "Sworn Friends" line, which is a reference to their first meeting and becoming each other's first friend in that world. He was talking about this one:
@HDMI1 But the "as expected etc" line has been used in other works as well, like Baka and Test or Kimetsu Academy, among others. It could just be coincidence or a common phrase, but it definitely has a classic shonen dialogue feel to it.
@wizardsonly It's just a trope-y way of prideful friends of a MC to speak in manga, if you read "Iruma-kun" you'll see that Sabnock speaks in a similarly pompous manner.
