@mycropen not sure it helps (it's not like I actually speak esperanto).
"uiata" is probably a typo for "uzata".

The rest more or less reads as follows:

The faded page beneath is barely legible. I can't read the first line, the rest goes something like this:

I can try to translate it with my meager knowledge, but it barely makes sense:

That last line is most probably wrong. I have no idea what "kosmarkoj" is supposed to be, it faintly reminds me of "koŝmaroj" (nightmares), or it could be based on "kosmo" (space).

I updated the chapter with a new TL note. After some more research, Yuu's log book seems to be written in Esperanto.

Setting aside Umika's severe social anxiety and Akeuchi's actual sinister identity, this is unbearably cute.

A bit yuri I think

Interesting backstory, I think she's really something supernatural because she really has telepathy. Alien or not, something or someone gave her that power.

this is really promising so far

I wonder if we're in for some kind of twist. I wasn't expecting any kind of strong through-line from the first two chapters but the amnesia mentioned here makes me think there actually will be one. I wonder if our "alien" actually is one at all, or if she's just very empathetic and thinks she's an alien because of her memory loss?

Either way this is such a great manga.
