Soap Bubble is a character that gathers and mixes various materials to easily make as much as you want whenever you want, flies around freely, and pops bubbles.

It flies freely through the world of imagination. When it catches the sunlight, it emits a radiant rainbow glow and reflects the world like a mirror.

In other words, a soap bubble is also a rainbow. The meaning of a rainbow within a single light is that while each person has their own unique color, there are actually hundreds of colors, even though Newton selected only seven. Therefore, within those soap bubbles exist the colors of countless diverse people, and the existence of people is quite attractive.

Each of them is a special being with a unique color. That is why they were created as characters, and that is why I like them.
