Kanji Quest the Ninja Master

This game focuses on Japanese Kanji characters.
Kanji is a uniquely shaped Japanese character. It has as many as 3000 varieties.
Some of them have similar shapes, which confuse us.
Try to find one kanji with a different shape from the many circles in which it is written.
It is very frustrating but also educational at the same time.
If you complete this, you will experience the irrationality of the Japanese language.
