Dear world travelers, let's go on a wonderful journey to various worlds together. Here, there is a primitive world coexisting with dinosaurs, a world of high martial arts that resists alien beasts and survives with difficulty, and a magical world that summons elves to resist disasters...
In these worlds, mathematics is like a link that connects the powers of all worlds. Witchcraft, martial arts, and magic all require mathematics for practice.
Dear powerful travelers, keep up the pace and don't fall into the rift of time and space while traveling!

It's very beautiful, even though it's been discontinued, but it's not bad. The current version is also very beautiful. It can be regarded as a comfort to my childhood.
