Since Tenchi lost his ability to create Light-Hawk wings after the return trip in time, in the previous episode "Z," it seems weird how he was able to use some powers in this episode to try to stop the Chobimaru.
First appearance of Lady Tokimi in her child form.
In the english dub, Tenchi calls the nearby planet Jupiter while the planet is clearly representing Saturn. The sub calls it Saturn.
If you hear when Baguma recognizes that they were being "held captive" inside Tsunami, you'll notice that Tsunami has a much vaster landscape. However, in the OVA episode "We Need Tenchi," Tsunami's landscape is much smaller compared to how it is depicted in this episode.
Ryo-Ohki in two places at once?
Ryo-Ohki manages to be in two places at once; as a spacecraft form with Ryoko. She is also with Ayeka and Sasami in cabbit form.
Later on she dances as kid-size Ryo-Ohki on the Juraian ship while her spacecraft counterpart spins along with the same motions.
This is the first episode in which Sasami fights, not counting when she was Pretty Sammy.
Lady Seto is Aeka and Sasami's grandmother (Misaki's mother). Seto has a second-generation tree Mikagami.
Lady Seto is often referred to as 'Oni-Hime' which means 'Devil Princess'
(Japanese Shinto religion is polytheistic, Kami are benevolent gods or spirits and Oni are malevolent spirits)
Noike has a third-generation tree named Kyouko. Kyouko is experimental and has nearly the power of a second-generation tree.
Noike cuts her hair short in this episode, like it was in her GP days.
Noike is Mihoshi's former GP partner (which is amung the reasons for her comparisons to Universe's Kiyone). Noike is also the adopted daughter of Seto.
Ryoko is unable to survive in space without a helmet in this series, whereas she could in the OAV and TV series.
Ryo-Ohki appears to have recovered enough to be able to transform into a spaceship again, and yet none of the girls consider using her to take them to Tokyo.
When the phone is ringing at the Masaki house, both Azaka and Kamidake's markings are blue, even though Kamidake's are usually red.
Although Pseudo Dad appears to run quite far between dropping the women he picks up, Sakuya and the other women end up being quite close to each other.
The Dark Guardians said 'Terminate!' 32 times.
The Gems of the whole gang are these:
The Shrine's Gold Japanese Letters means 'Tsuchida Shrine'.
When the Spirits were defeated, there were types of Money: Gold stones, ordinary Stones, a Stone Wheel, and rocks with sticks.
Kazuhito's wife Itsuki looks exactly like Tenchi's mother Kiyone from the OVA series.
