After destroying the Floating Gardens to save a baby bird, ditzy Princess Lapis of Sorcerland is banished and must undergo a long journey back home to the Diamond Palace. With her for the adventure are a young fairy, a directionally-challenged immortal, and her math tutor.
Armed with the powerful magic eraser, and an unmatched love of pudding, Lapis continues forth righting the injustices of the world and defeating magical foes—even if it means she destroys the kingdom in the process.
Detatoko Princess contains examples of:
- Affectionate Parody: Of High Fantasy.
- Anti-Magic: The Magic Eraser erases all magic within its blast radius.
- Big Bad: Topaz, who sends monsters and groupies to hinder Lapis throughout all three parts. She's pretty ineffective, though.
- Butt-Monkey: Kohaku and Topaz get the brunt of a lot of comic relief, and Kohaku's status as an immortal swordsman makes him a very handy human shield.
- Cool Old Guy: Jii, Lapis's math tutor, is the only sane man among the group and can still pack a punch.
- Destructive Savior: Lapis's modus operandi is to destroy the kingdom in the process of saving it, and wrecking the floating island to save a baby bird gets her kicked out of the castle at the start.
- The Ditz: Princess Lapis is a well-meaning but ditzy girl, and Topaz is a ditzy villain.
- Evil Overlord: Lady Elena lords over a town and demands they pay her taxes.
- Fastball Special: Jii throws Kohaku in the way of some arrows, using him as a Human Shield.
- Foe Romance Subtext: Topaz collects girls from all over and plans to add Lapis to her collection, and grows very concerned when one of her groupies comes close to actually killing her. Lapis, for her part, is completely oblivious.
- Golem: One is seen in episode 2, made of pudding. But it's actually something else.
- Good Thing You Can Heal: Kohaku's immortality is often played for laughs when he gets hurt.
- Here We Go Again!: The ending has Lapis being banished from the kingdom yet again, with Topaz in hiding to battle her.
- Human Shield: Kohaku is used as this once, as he can't die.
- I Choose to Stay: Played for laughs when Lapis wants to stay in the Pudding Forest forever.
- Ineffectual Sympathetic Villain: Topaz tries to be threatening as Lapis's rival but isn't up to the task, and the villains of the week are more threatening than she is.
- Like Mother, Like Daughter: Like Lapis, Queen Sapphire isn't too bright and accidentally sends her daughter to a dangerous land.
- Mundane Made Awesome: Pudding drives a lot of the plot.
- Not-So-Harmless Villain: After being forced to work out nonstop by the Fitness Brothers, Topaz casts a huge bout of flame magic that takes them all down temporarily.
- One-Winged Angel: The Fitness Brothers combine their powers and turn into a giant, adorable three-headed pig that shoots lasers.
- OVA: The anime adaptation, which had 3 episodes.
- Paper-Thin Disguise: The king and queen disguise themselves as a baseball player and magical girl to help Lapis secretly. Lapis thinks they look familiar but can't place it.
- Pint-Sized Powerhouse: Annie, the eight-year-old swordsman, has a magic sword that's very deadly.
- Trademark Favorite Food: Pudding, for Lapis. It's exaggerated to the point where she literally needs it to live and refuses to hurt a golem made out of pudding.
