Okay kiddo, let me explain what a reikon is. So first, do you know what a ghost is? It's kind of like that, but in Japan they have a specific word for certain types of ghosts called reikons.
Reikons are said to be the spirits of people who have died, and they're known for causing mischief and sometimes even harm to people. Some people believe that they can see reikons, and others think that they can sense their presence.
In traditional Japanese culture, people would often leave offerings for the reikons in order to appease them and avoid any bad luck or negative energy. Some people even think that they can communicate with reikons and ask for their help or guidance.
Overall, reikons are a spooky but fascinating part of Japanese folklore!
