During the D of D tournament, Sakaki shrugs off much of Niijima's complaints of the Shinpaku Alliance's members suffering injuries, stating that he was shot by his enemies and told that he wouldn't be able to live. However, he was still able to enter a Karate tournament and win first place. This is an exaggerated parallel situation to one presented in The Karate Kid. (This feat did actually happen and was mirrored by Hongou who came out of a coma to participate.)
Particular Kata Sakaki can be seen training the techniques of are Wansu, Sanchin, Niahanchi, Passai, and Seisan. His earlier matches with Hongo also showed proficiency in the sport karate style, though he used a more combat oriented version than otherwise shown in the manga. While Sakaki has trained the techniques or used the techniques taught in those Kata it is rare that we see him or Kenichi actually drilling Kata (More likely done off panel to avoid repetitive sequences)
