D-Dial

The D-Dial or sometimes called The Dial is a special device invented by Lala Satalin Deviluke.

Features
Like a standard phone, Lala can use it to call other people. But unlike a standard phone, it uses dimension technology that contains her inventions which she uses to "call" upon them. She has also made copies for her sisters.

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 the Gogo Vacuum-Kun (a giant vacuum that has eight tentacles and has a much stronger sucking power than a regular vacuum) against Zastin, Maul and Smutts.

From then on, Lala has used it on a recurring basis every time she brings out an invention.

Later on, it is revealed that she had already created other versions of her D-Dial for Nana and Momo, who use them to call upon animals and plants respectively.

Lala Satalin Deviluke
In Lala's version, her D-Dial can summon her inventions she has created from a virtual space into the real world.

Nana Aster Deviluke
Like the original D-Dial, Nana's D-Dial can also summon from the virtual space within it. Instead of gadgets, Nana's D-Dial lets her summons animal friends she's met from other planets. She teleports her animal friends from her Cyber Safari park, a large virtual ecosystem where her pets may live in environments close to their home worlds. It also serves as a catalog to investigate the statistics of animals, such as their species or their powers.

The first time this version of the D-Dial was seen, it was in Chapter 108, along with Momo's.

Momo Velia Deviluke
Like the previous D-Dials, Momo's D-Dial can also summon from the virtual space within it. Momo's D-Dial lets her summon plant friends she's gathered from other planets. She keeps many different plants in her botanical Cyber Garden in virtual space, and when she calls and teleports them, they may appear and grow immediately out of the ground or may grow right out of her D-Dial. It also serves as a catalog to investigate the statistics of these plants, such as their species, their healing powers or abilities that they may have.

The first time this version of the D-Dial was seen, it was in Chapter 108, along with Nana's.
