and in this case, neither kana nor kanji explain each other...

according to wikipedia article on furigana,

 Also, because the kanji represent meaning while the furigana represent sound, one can combine the two to create  puns  or indicate meanings of foreign words. One might write the kanji for "blue", but use katakana to write the pronunciation of the English word "blue"

A similar practice is used in native fiction to clarify extended meanings. For example, in a work of science fiction, some astronaut could use the word  ふるさと ,  furusato, meaning "my hometown", when referring to planet Earth. To clarify that for the reader, the word  furusato (hometown) might be written in hiragana over the kanji for  chikyuu (Earth).

which neither kana translate kanji nor kanji translate kana, just one of them be the surface meaning and the other the extended  meaning...

which's also what I'd said about those crystals..and especially in the case of kanji, I think those kanji are the name of objects in system while kana are how players say them..or reverse..
