I tried to translate that earlier as it was posted, but I got tons of errors.. Lalafels are too weak was all I could understand. (弱すぎるララフェル) ..I have no idea where semicircular canal came from so I gave up.

THE PRIMALS had a concert in Osaka a few days ago and a quick google search suggests the concert site was extremely close to Universal Studios Japan. It sounds like bkub and fakkuma went (possibly together? idk if there's a precedent for them hanging out irl?) to USJ before the concert and got motion sick/disoriented from the rides.

Yep, the two of them went to the Eorzea Cafe together, and each of them made a 4 page manga about it. bkub's version starts here and Fakkuma's version starts here.
