A novel in which the main character is a cub. (Emphasis added: It is not the protagonist who raises cubs.) For specific information, please read the introduction of the novel. I saw them all a long time ago, so I don't really remember them.
The content is as the title suggests, about two children trying to survive in the apocalypse. I don't remember the specific content, but the main character is very cute. The author of this article likes to write novels in which the protagonist is a child. If you are interested, you can check out the author column.
If you do not accept double x, you can skip it (see the introduction to demining for details). I forgot the specific content, but Zaizai is very cute! !
