Maru-Maru Change-Kun

Maru Maru Change-Kun or Mr. Complete-Change is one of Lala's inventions.

Feauture
This invention swaps bodies of its users, but the physical strength is based on their own original.

The first version is a big machine with two capsules (where the bodies lie in) and the computer between the capsules. Once the bodies are swapped, they need to get in this invention for returning to normal.

Its smaller version names the Maru Maru Change-Kun Revised Beta, which looks to have pink oval body with Deviluke symbol, yellow ornament, a display and handles as fixing its pink-colored body between. It is characteristic to be portable in size whose function is the same to its predecessor. This invention is activated by which two users grab each handle of the invention to swap their bodies. The renovated version has a new function that limits the time of its effect in duration and the users cannot quit intentionally until its determined time ends.

Appearance


The first version was used three times in the manga:


 * The first time in chapter 43 when Lala swapped Rito and a stray dog after hearing Rito wondering how nice to become a dog.
 * The second time occurred in chapter 105 as Lala swapped with Haruna in order to capture a criminal who chase the girl. This story is adapted in episode 4 of Motto To LOVE-Ru.
 * Lastly Yami and Mikan swapped bodies for a day spent in chapter 139. This story is also adapted in episode 8 of Motto To LOVE-Ru.

The second version appear twice in To LOVE-Ru Darkness:


 * In the chapter 18 (adapted in the OVA 3 of the anime), as Rito and Haruna takes care of the invention when Maru Maru Change-Kun suddenly falls off and Haruna and Rito grab its handles before crashing on the floor, therefore their bodies are swapped.


 * In sixth bangaihen chapter (adapted in the OVA 2 of the anime), it is used by Nana and Momo to change their bodies in order to test Rito and he finds that Nana is cute, despite her flat chest.
