Suke Suke Goggle-Kun

Suke Suke Goggke-Kun or Mr. See-Through-Goggles is one of Lala's inventions.

This invention is the glasses that provide the transparent vision by regulating the transparency at its dial. Lala originally uses it for looking through the inside construction of the inventions when she checks these inventions.

It is also used to look through the clothes that persons are wearing and it is only used in the series in this incorrect way.

This invention apparently looks normal glasses with an yellow dial at its left temple for regulating its transparency and Deviluke's symbol at the centre of the glasses between the lenses. This invention is blue-coloured in Motto, but in OVA 2, its colour is light-grey and partially blue.

Appearance
In the chapter 109 of the manga (adapted in episode 3 of Motto), this invention is used by Rito when he find the glasses in a bedroom of his room and he wears the glasses, and immediately he sees through the clothes of persons around him, as when Rito sees Mikan, he is surprised that her clothes is invisible and her underwear is seen. But not only then, he finds that he cannot take off the glasses and he goes to school while wearing the glasses and look through the clothes and inner clothes of the schoolgirls. Then he modifies the dial at the middle, at the edge of the glasses as now he just doesn't see through the normal clothes.

In the fifth bangaihen chapter of To Love-Ru Darkness (adapted in the OVA 2 of first season), the glasses are used by Rito as he smelled the Jikido Flower which drastically changed his personality and then used in an intentinal way. He uses this invention for going to school again and see all nudified classmates of the school. He plans to manipulate Haruna with this invention but Momo stops it and makes him smell the Kenja Flower. His personality is turned normal and this invention never appears again.
