D-Dial

The D-Dial or sometimes called The Dial is a special device invented by Lala Satalin Deviluke. When a D-Dial malfunctions, it has shown to randomly summon objects from the user's virtual space into the real world.

History
The original user of the D-Dial was Lala, being its inventor. It first appeared in Chapter 1 of the To LOVE-Ru series when Lala used it to summon Vacuum-kun (a giant vacuum that has eight tentacles and has a much stronger sucking power than a regular vacuum) against Maul and Smutts. Later on, she created other versions of her D-Dial for Momoand Nana.

Lala Satalin Deviluke
In Lala's version, her D-Dial can summon her inventions from virtual space into the real world. The inventions that it has summoned are:
 * 1) Vacuum-kun - a strong vacuum that sucks anything on its path.
 * 2) Pyon-Pyon Warp-kun - a bracelet that can warp living flesh. Its only bugs are that it cannot warp clothes, and that it just warps the user to a random place.
 * 3) All-Purpose Tool - this invention either has the ability to modify a pre-existing invention, or it can transform itself into a new invention.
 * 4) Buzzing Bat-kun - a bat that has rockets attached to it, and can hit a home-run ball. However, it blasts the user during the recoil.

Momo Belia Deviluke and Nana Astar Deviluke
Like the original D-Dial, Momo and Nana's D-Dials can also summon from virtual space into the real world. However, instead of gadgets, their D-Dials summon plants (for Momo) and animals (for Nana). The plants and animals it has summoned are:
 * 1) Giga Wild Boar Gii-chan - a giant wild boar from Planet Shishirabe that Nana summoned to defeat Zastin, Maul and Smutts.
 * 2) Shibarisuki-san - a giant tree from Planet Okiwana that Momo summoned to defeat Zastin, Maul and Smutts.
 * 3) Watermelon-san - a giant watermelon from the Melon Planet that Momo summoned to play melon splitting with.
