>>4671488Since you already watched Kagami, try Yashiro or Chaika since they often collab with him. Maimoto or Rikiichi are also good if you don't mind their boomer references.
Other than the ojisans, Kenmochi is always a good place to start if you like zatsudans and interaction. Shellin is another good one, he's pretty easy to understand as he speaks very clearly and generally good for background noise, unless he's playing horror games since he's fucking loud.
