My story is considerably less engaging than most people, but whatev.
When I was fourteen, I was quite an obsessive fan of Pokemon for the characters, rather than the plot. Ash, I thought was blah. My absolute favorite however was Richie, or Hiroshi. Anyhoo, I obsessed over him, drew him, wrote about him, for.. err.. maybe a year? I bought the manga with him in it because he was freaking adorable, and in it, his Pikachu was named Chuchino, rather than Sparky (or Leon, which is so much cuter than Sparky, zomg).
Anyways, I thought it was the cutest name ever. When I joined, I was already recovering from my Richie obsession, but Chuchino was such a great name! Not many people read the manga, and those who did probably wouldn't remember a minor character's Pikachi, after all. Figuring it was perfect as a name, I typed it in and voila.
