Sugitani: A huge sentient tree with a face on it from the planet Cedar. It produce a certain pollon that whoever breathes it in will act freely and express thier hidden desires. Evidently Devilukeans seem to be immune to it's effects, although it had no effect on Rito what so ever, this could be due to him already being honest with himself, any other reason if any is unknown. The tree seems to have perverted desires as when it breathed it himself, it started molesting Nana and Momo.
