Chapter 40

Chapter 41 is the fortieth chapter of the Astra Lost in Space manga. It is the third chapter of the Galem arc and, in the compiled volumes, the third chapter of the fifth volume.

Synopsis
111 days have passed since the students of Caird High School have been stranded in deep space. Onboard the Astra (ship), they soon approach their final destination, Planet Galem. Aires remarks she has achieved her goal of becoming friends with everyone onboard the ship as they soon land on the planet.

On the ground, they realize that the planet is made up on huge amounts of bio-luminescent species on the planet. The group splits up to collect food, water, and other supplies, with Paulina dryly remarking that they are very used to this. Kanata and Aries are impressed by the wildlife and diversity of species on the planet, and they both wonder what their lives will be like when they return home.

As Kanata continues to forage, he continues to ponder the idea of who the killer is, but tries to shove the idea into the back of his mind, as he feels like everyone has gotten along so well, that even any killer has formed a special bond with them. His main worry now is trying to get home and he hopes that the idea of a killer never existed.

As he returns back to the ship, a sudden wormhole appears right next to him. He barely has time to react and sprints to a nearby cave, far enough until the wormhole disappears. He runs into Aries, who came from an entrance from another side of the cave. He soon realizes that the killer is still among them, and willing to kill them all on the planet and take the ship for themselves, but must do it away from the ship in order to avoid damaging the ship. He realizes he has figured out who the killer is, and begins to devise a plan to capture the killer.
