Adrena Flower

Adrena Flower is a flower with five pink-colored petals which Momo uses for invoking the Principal excited.

It has the opposing effect to Philosopher's Flower.

This flower is unknown about the planet where it comes from as well as its origins.

It apparently smells towards a person to acquire adrenaline for excitement as its name implies.

It appears in the chapter 4 of To Love-Ru Darkness and in the episode 3 of To Love-Ru Darkness, as Momo uses this flower for making the Principal excited thus he goes after Rito and Yui.
