Deru-Deru Vision-Kun

Deru-Deru Vision-Kun is one of Lala's inventions which is used by Lala in order to entertain the frightening challenge by showing a ghost made by hologram.

It looks a round mechanical device with a black round grinning symbol of white eyes which is capable to create hologram for terrifying ghost. This invention seems to project the hologram from its black round orifice above its black grinning symbol, and it is able to explode when something is collided with this invention. This invention seems to be the unique one which doesn't have the Deviluke's symbol, it is supposed at least from which its visible aspects. Its eyes are similar to the ones of Mira Mira Show-Kun.

This invention only appears in the chapter 16 of To LOVE-Ru, when Lala uses it for showing skull-headed ghost which wears armour by hologram to frighten Rito and Haruna. But Haruna doesn't respond to its most terrifying form and throws Rito straightly into the device. When Rito collides with the device, he causes the device cracked and the device explodes. Therefore, obviously the explosion caused the reason why this invention never appeared again in the manga.
