Dopant, in addition to the elemental memory used by the protagonists

The memory used by the weird people, that is, humans who want to satisfy their own short-term pleasure, is somewhat different. Their memory The surface texture looks rather evil, and it is distinguished by English letters independently of the element memory, and the memory they use is only a general commercial product with the possibility of mass production.

Monsters transformed by ordinary commercial-level memories are called "dopers." It seems that the villain organization in the play uses high-level memories, and it doesn't look like it. What a good thing, the memory used by the protagonists has a T2 version in the theatrical version, which is called "next-generation memory".
