In the final episode,

> Ichika is shown at the end of the finished movie wearing the clothes Nanami
> brought from Bolivia, so it is inferred that she somehow returned to Earth
> after being abducted by the unmanned probes from the Federation search
> party.

So my question is not about this particular part of the ending.

Is there any official material (manga, OVA, ONA, etc.) that tells **how** it
came to that ending?

> How did she return to Earth?

What happens to Ichika after the fated summer ends?


Ichika said that the earth was forbidden to be visited unless they had
interstellar travel. In the end, we clearly see Remon with the schematics of
Ichika's ship. This means that they must've made contact with aliens, joined
the federation, and she could live with Kaito.

At the end of the last episode, Kaito's sister returns and brings a Bolivian
sweater for Ichika, but Kaito tells her she had to return to her own country
as her transfer had ended. We then see Remon at MIB headquarters with the
plans for the interstellar ship and Rinon is there with her.

If you watch till the end of the credits, one year later, some students are
watching the old class members' student film and it shows Ichika wearing the
Bolivian sweater with some revealing dialog.

We are given an OVA where you can see Kaito and his friends 2 years after the
ending of the series. At the end of the OVA, you see Ichika crying tears of
joy while she is looking into space. We can see that she is on a spaceship
with her sister.

If we compare the ending of the series, where Remon-senpai build that ship and
we can see Ichika in that sweater (or whatever) Kaito's sister brought from
Bolivia after she left, with the information we get from the OVA, we can see
that over 2 years had been gone till she came back

If you listen closely towards the ending of the show, one of the students
said, that the movie was made by a graduated one this year. So, Kaito is now
out of school, which means he ended 3rd class (2 years from 1st class till 3rd
class). So, Ichika returned before he ended class (because of the movie, being
published on the last day of school) but stayed about 2 years away, and now
Earth's technology is at the point where she can stay and we have a happily
ever after.

Happy ending!!!

They have already told you about the ova, in chapter 12. The students were
told that the movie was shot by former students and Ichica has the poncho of
Bolivia. I think she came back a year after arriving, because they were in the
first year and practically canceled the movie, as everything was recorded in
the summer, they had to wait the following year (second year) and if they were
already alumni, they would have spent at least three years (second, third and
present year). Also, ... In the manga ....
