Gigantic Gas

Gigantic Gas is a gaseous agent which Nemesis found after defeating smugglers for her leisure.

This gas doesn't have a specific form, as it only seems to be contained in a deformed case with an eye, and at upper part, a beak for spraying the agent.

It turns ones getting sprayed into enormously larger size, as much as some ten times larger temporarily.

But for earthlings, this agent affects an opposing effect as it rejuvenates the age as young as a baby as to Rito.

Background
This gas was developed in a kingdom during the Second Galactic War.

When this gas was released, it increased the size of any beings temporarily, and thanks to it, dozens were turned into titans.

This gas raised the army of gigantic soldiers, but it only lasted three years, as this threat against the galaxy was ruined by Deviluke,

Plot
This gas appears in the chapter 51 of To Love-Ru Darkness, as Nemesis sprays it to Rito, she talks him that she had taken out this gas to smugglers and she also wanted to prove it with him, but the effect gets completely contrary as Rito gets rejuvenated, and finally turned into a baby.

Trivia
The effect of this gas for Rito is only similar to Modori Skunk's gas, as its effect also lasts temporarily to rejuvenate anyone.
