1. The weird ass announcer from chapter 80.
  2. The hacker from chapter 102.
  3. Tserriednich's matchmaker from chapter 345.
  4. Glasses guy's manager, first appeared in chapter 341.

Personally, I think the hacker and the manager do deserve dedicated pages, the former is the main speaker in the chapter in which he appears, and the latter is one of the two main ones in chapter 341, and appears again in chapter 342 (overall, more than the Hunter Association Agent). Even the announcer speaks more than some of the characters with an unofficially titled article, and despite not being heard speaking himself, the matchmaker is talked to more than, say, Battera's lover.
