This alliteration and identical amount of syllables throw me off, so I end up combining her names (Since she always introduces herself with the opposite name Godai calls her) and I end up getting confused and just typing "The girl" when referring to her.

Anyway, 13. The fish Grongi who screwed over the rhino returns and starts a rampage, first on a large boat, then on some dock and shore workers who accidentally got cut.
As all of this goes down, a man pretending to be an unknown lifeform shows up. However, he has given up on humanity and might have mental issues.
Meanwhile, Jean has uncovered more ancient artifacts, and this is making Kuuga's Spidey sense go crazy, flashing visions to him mid-fight. I'm particularly interested in where this is going.

Anyway, the Grongi are counting their kills, which was obvious since the bracelet, but it's good to know with certainty. I'm still a little confused as to why, but I guess we'll get there.

As for Sawatori, yeah, she is kind of a plot device. As much as they try to give her a character, it seems that all Godai and Ichijou ever do while interacting with her is "Translate the thing. Have you translated more of the thing? Please keep translating the thing."
