Bretty gud. Only two places I couldn't hear what was being said but I somehow figured them both out after relistening n times. This shit is so much easier with a transcript.

Anyway at first I thought the Onara was supposed to act as family name but not even once there was Onara-san used on it's own. When name appeared it was always with Onara at the beggining which leads me to believe the meaning is that the characters aren't Makoto Surname or Tsubasa Surname (the people) but fart versions of themselves of which they're constantly reminding viewers about so Fart-Makoto and Fart-Tsubasa seemed like the right way to go.

Natives do tell if some part of the text feel wrong.
