Ho fatto una ricerca, "Pound Cannon" è la stessa tecnica delle "Passioni della Fenice; in pratica:
Ittoryu(1 Spada)
-36 Passioni della Fenice
-36 Pound Cannon
Nitoryu(2)
-72 Passioni della Fenice
-72 Pound Cannon
Santoryu (3)
-108 Passioni della Fenice
-108 Pound Cannon
Quote:The attack's name is actually a very heavy pun, it's written out as "Phoenix of the 36 Earthly Desires" in the Manga with a skewed reading attached that makes it "36 Pound HÅ" when read out. HÅ means both Cannon and Phoenix, however the attached Kanji is for Phoenix, making that the literal translation and the "Cannon" reading a Pun on that, both of which are correct. The "Pound" part is a skewed reading of the Kanji "Bonnou" for Earthly Desires, and it is referring to the Caliber of a Cannon. (a 36 Caliber Cannon would fire a 36 Pound Ball) This technique is known as 36 Pound Phoenix in the Viz Manga, 36 Caliber Phoenix in the FUNimation dub (and sometimes the Viz Manga) and Single Sword Rising Phoenix in the 4Kids dub.
Se qualcuno riesce a tradurmelo decentemente, visto che il mio inglese fa un po' cacà xD
