In case you want a list of all the powers you gain access to as you grow more tail The elements are broken down into 13 categories and the kitsune are divided into each type: Kaze (Wind), Chikyu (Earth), Kasai (Fire), Kawa (River), Tengoku (Heaven), Sanda (Thunder), Yama (Mountain), Kukan (Void), Seishin (Spirit), Jikan (Time), Mori (Forest), Umi (Ocean), and Ongaku (Music)
They all have access to magic just ignore that Void is darkness music is basically sing/ play a song and what ever you played becomes real for example the songs link plays on his ocarina time power though are to op and will never be accepted and you can't naturally have light and darkness together so since your starting of with fire that means you have the potential to gain access to lighting, metal, earth, water, ice, wind, sound/ music and light or darkness depending on weather your a kitsune or a nogitsune 

Edit oh the reson water and earth are mentioned two or three time is because water and ice are separated and earth has plants as well as metal
