Find a Japanese anime Alien Invasion of the Earth.

The Japanese comics you are looking for may be bubbles.

Bubble is a Japanese sci-fi animated film released by Netflix in 2022, which tells the story of an alien occupying the earth. In this story, a strange alien species landed all over the earth in the form of bubbles, which is called "bubble falling event" by the world. These bubbles are conscious and can all be gathered together to become a huge bubble aggregate and a new species similar to the leadership. They tried to infiltrate the whole earth slowly and take it for themselves. In the "bubble falling incident", the hero heard the song of one of the bubbles (the heroine), which made other bubble families angry. At the end of the story, Xiang gradually broke through herself, overcame her fear and anxiety, and bravely went to the most dangerous place, just to save the girl. Their emotions also sublimate in this process and become touching emotions that depend on life and death.

However, at present, there is only the first episode of a season, "Bubble will be uncertain ~". If you want to see the follow-up, you can only pay attention to the relevant information.

This cartoon is not finished yet, so it is impossible to determine what its follow-up content is. If you can provide more details or information, I will try my best to help you.
