@pancakesXD There's one more thing that should be added to your explanation. That is, everything until the final four pages is happening in the "present". The spider was surprised to see the older En no Ozuno and Zenki but initially brushed it off because he thought he'd simply failed to notice the passage of time, being immortal and all. But he was right the first time. Not that much time had passed since their earlier meeting and the two should not have been that old.
@Egran No, there are two loose ends. The entire sequence of chapter 6 is happening within Miyo's "present". She smelled the incense, went into the dream to see En no Ozuno's past, found her older self, was helped by dream-Zenki, then went on to find the real Ozuno and Zenki. That means there are two loose ends:
1. Goki-sama came from the future to Miyo's "present" to help her(self). We know this is the real Goki because dream-Ozuno says so. This Goki had not met Miyo in the village yet because she was surprised that Miyo already knew her. So this is Goki before her first chapter meeting with En no Ozuno.
2. Goki-sama met up with the spider BEFORE the spider tasked En no Ozuno with returning Kip's mirror, allowing the spider to send her to the time just before she met up with En no Ozuno and Zenki in the prelude for the first chapter. We know this because the spider is only now writing the note to Kip, so the final jump from chapter 6 to chapter 1 is actually a jump FORWARD in time. This the same Goki from the palace further in her timeline, having somehow jumped back to meet the spider.
That means there are at least two more time travel incidents involving the Goki from the future before she went back to meet up with older En no Ozuno and Zenki as seen at the end of chapter 1: The initial jump and the jump to meet the spider. We thought from chapter 1 that she jumped straight to the meeting in the forest, but she didn't. She had to jump back to the palace to help her younger self, then jump back to the spider before he returned the mirror, prompting him to write the note and ask Ozuno to return it to Kip, then she jumped forward in time to just before Ozuno and Zenki met Miyo, then she used Kip's mirror to jump back to when Ozuno and Zenki were waiting for her. The second jump in this sequence (meeting the spider) may have been achieved by her simply going into the spider's domain because time is always in flux there.
In short, Goki-sama already performed four known time travel jumps in a sequence (that we know of):
1. Jump back in time to the palace to help Miyo.
2. Jump back in time to meet the spider before he returned Kip's mirror, prompting the spider to write a note to let Goki use the mirror.
3. Jump forward in time to meet En no Ozuno and Zenki just before they met her younger self.
4. Jump forward in time using Kip's mirror to return to her proper timeline and reunite with the older En no Ozuno and adult Zenki.
