Premieres October 2024. The new PV is here. I will edit in an English language article when I find one, but here is the Natalie source (edit: ANN article). Synopsis from AniList:
Momo Ayase strikes up an unusual friendship with her school’s UFO fanatic, whom she nicknames “Okarun” because he has a name that is not to be said aloud. While Momo believes in spirits, she thinks aliens are nothing but nonsense. Her new friend, meanwhile, thinks the exact opposite. To settle matters, the two set out to prove each other wrong—Momo to a UFO hotspot and Okarun to a haunted tunnel! What unfolds next is a beautiful story of young love…and oddly horny aliens and spirits?
Edit: Just wanted to point people to the newly created community [email protected] as well (potential spoiler warning)
This manga is so good. I'm stoked.
