A game with unique quests for unique items. Only in a manga. But this specific one makes sense for this specific manga. There's quite some stuff created for Crim specifically.
And devs would never make the base item you need for the upgrade a rare Boss or Raid drop that is account-locked.
No sirree, they wouldn't think of that at all ......
Special privilege as the devs' kid. I know it ain't common but it does happen, parents like spoiling their kid like that. Don't worry, nobody will ever know or suspect it anyway, cause plot reason.
I love the contrast with the npc speech with the player speech, or more like I like how is maintained, some other player would be like skip skip skip or "just tell me what to fight and be done with it"
