Tsuki-chan from the residential neighborhood is a violent girl whom everyone fears. Shinsuke-kun from the housing complex tries to stand up to her alone, but ends up getting beaten to a pulp instead. Their fight drags in their mothers, their fathers, their friends—everyone gets caught up in it... And finally, the residential neighborhood and the housing complex are locked in a massive war!
...Honestly, it's a big mess.

This controversial masterpiece was originally released in 1971, amid high tensions around the world. And still in the present day of the 21st century, where it feels like all sorts of different moods are in the air, I would be delighted if everyone—not just children, but adults as well—would take a moment to reflect on what this picture book portrays. Whether you can't wait for war to start or you absolutely hate the idea of it, this is a must-read!
