S1·E11 Don't Go, Senpai

Emika is retrieving Ichika because the latter is on a planet where contact with its lifeforms is forbidden under their Federation laws, and the only solution is for her to leave this planet before things get messier. Ichika reluctantly agrees, but changes her mind when Kanna and the others arrive to stop her. Learning certain information from Emika, Remon tells them that Ichika may stay if the earthly spot Ichika has seen in her imagination is found in order to prove a probable previous contact between aliens and human beings. As the group finds the place, the search team arrives and starts a pursuit. Since Rinon's teleport function becomes disabled, Remon takes the others to the spot using a van specially prepared with Emika's help; with Tetsuro, Mio, and Kanna becoming bio-signature decoys for the pursuing rescue craft. However, a few kilometers from the site, the rescue craft overturns the van.
