Etymology
Translating this back into Japanese gives 神秘的, 'Shinpiteki' (hence the JASRAC version of the title).
 * 'Ne' is written as 'ネ' in katakana.
 * 'Mousu' is written as '申す'.
 * Combining ネ and 申 results in the kanji 神. This can be combined with the '秘' in the title, resulting in 神秘, 'mystery'.
 * Adding the 'OUS' at the end of the title results in 'Mysterious'.
