Depending on how far you want to dig, Urusei Yatsura and Rosario+Vampire are both 'anime games' both on Japanese and both fairly empty headed experiences dedicated to the fans of the shows.
And that is just the tip of the ole iceberg. I could likely name off 50 titles. Which would sound neat till you realize they will be all Japanese only and basically all somewhat flaky experiences based on animes that really are more or less what some anime is all about, boobies and panty shots. Leaving little to make a realistic use of your time DS game.
