Trivia

 * In the episode, Akane learns of Ryoga's feelings for her from a love letter that he wrote to her, but since he never signed the letter she still isn't aware of Ryoga's love for her.
 * In the episode, Akane reveals in the letter that she is already in love with someone else, but doesn't reveal to who it is.
 * Ryoga's dog Shirokuro has changed considerably compared to the manga counterpart. In the manga, Shirokuro is a female and mostly live in Ryoga's home (evident by her giving birth to several puppies). In the anime, the dog is male and comes from a ninja village, the same one that Sasuke Sarugakure comes from.
