Rikuru Shigekuni Yamamoto (リクル 山本重國, Yamamoto Rikuru Shigekuni) was the former captain of the 12th Division in the Gotei 13. Her lieutenant was Bubbles Kurosaki and was a protagonist character.
Rikuru is a young-looking adult woman in the Gotei 13. She is commonly noted for her long golden blond hair which sometimes look like strawberry blond, and was dyed black and silver before. She has blue eyes which, like Sora, turns to red at times.
Rikuru is an energetic, cheerful, and somehow childish at times. She likes to read books and make potions which may affect the Gotei 13, like the Gender-bending Potion. When her eyes turn red, she seems much more knowledgeable, mature and colder than her usual self.
- Gender-bending Potion: One of Rikuru's inventions, Rikuru made this and poured it on everyone so they will be gender-bent.
- Chibifying Potion: Once again, Rikuru made this and poured it on everyone so they will shrink and look like a chibi.
- Rikuru accidentally poured one on her stuffed toy and it gained a Human form.
- Sometimes, Rikuru pulls out some potions up her sleeve which turns her to a chibi or a cat.
