Anime chat group , you let me come only after the world is destroyed?

Just transmigrated to a new world… and it was destroyed. Takumi became the last human in this world. Fortunately, a chat group descended. On his first check-in, he received the "Cocoon of the End" and became permanently bound to this world. The stronger the civilization, the stronger his power. But... there are no more humans in this world. So, dear bros in the group, wanna immigrate? Free houses, free land, and even free superpowers! You don’t want those cursed children? I’ll take them!
