The Royal Patraine Computer (ロイヤルパトレーヌパソコン) is the upgraded version of the Pureleine Computer given to the group after acquiring the Royal Patraine title. Like before, it contains Oyajide in his alternate form and was used to help the Ojamajo.
Along with its previous uses, the Computer was mainly used to keep track of Hana-chan through the pin or brooch she wore after obtaining it. Their Yousei could also be sent through it to tend to Oyajide- namely when the girls had to try to persuade him to help them.
- It first appeared at the end of episode 31.
- It is the only royal Patraine item that doesn’t require Royal Seeds to work
