Suiton Suikoudan no Jutsu, translated as Water Release: Water Shark Bullet Technique, is a ninjutsu from the Naruto anime and manga series in which the user shapes water into a shark-like projectile. It is most closely associated with Kisame Hoshigaki, a member of Akatsuki known for powerful water techniques, and appears in battle scenes where water becomes a direct weapon. The spoken name became recognisable beyond the show as fans clipped battle audio for edits, AMVs and soundboards, where the rhythmic Japanese chant now signals a dramatic water attack even outside its original fight.
