At the foot of the youkai mountain, nearby of higan and under the home of Shinmyoumaru the "Needle Castle", he have a place who stinks and making people nervous with tiny sweatdrops on forehead "kusaïri" a dead area with in her center a tree with a giant durian, it was created by a mistake of Yukari Yakumo. not even the fairies youkai or humans... just to say nothing in Gensokyo dare approch kusaïri excect for good reasons... because her boundarie is made of faint stinky fog with flies. But very far away of kusaïri at the Hakurei Shrine, reimu sweeping her floor

Aunn: The legendary giant durian start her ripening!

Marisa: The one from kusaïri ?

Reimu: we are safe here

aunn: miss reimu, It can wilting plants foods flowers&crops quality getting worse or slightly change or spoil due to the odor effect, even sake and tea lose they’re flavors...

Aunn: when the giant durian open, the stench ripple outward&spread fast across in all Gensokyo in creating a faint small amount yellow ripple in the air for 1 second with a slight expression of discomfort&everyone body stiffen with they’re expressions contortes into a grimace of discomfort and disgust

Aunn: The day after the faint smell the giant durian hibernate but the smell will stain and wafting off around someone, it very deeply it may last for 3 days, if a faint yellow fog aura puffs out around her, she’s the "cursed victim" And how much her effort to clean herself the smell return on her...

Aunn: the curse scales with proximity and size… the smaller the victim like kobito, it better cause the victim stinks a bit but it not very strong... but if the victim size is like a human, lets just say everyone value her own nose.

Aunn: the smell when he hibernate not making a person the stinky victim... so everyone are safe until the next year, the radius around kusaïri haze bounduary and her guard post stinks but kusaïri just smell like normal durian so it smell like roses compared to being right in front of the giant durian

Shinmyoumaru: no one can approch the giant durian even hibernate without gasmask or determination, he’s very huge&grotesque, make him seem absurd&comic. The person nearby see her clothes dissolve&see her life flash before her eyes in pass out on the spot, that even birds faint mid-flight nearby, but my Mallet is uncharged so he useless agaist him...

the durian branch start to weakening, a small gust of wind gonna start to blow in Gensokyo, the wind gonna smell like durians

Marisa: oh no !

Reimu: the branch carried a giant smelly durian, it normal he’s creak

and reimu holding Marisa's collar

Reimu: don’t even try to escape, You gonna stay here to clean !

Marisa: come on release me reimu !

Shinmyoumaru: i hope whoever the curse victim gonna be, have someone she can rely to be with during those 3 days to comfort her&keeps her company, From far away

the giant durian open, the stench ripple outward&spread fast across in all Gensokyo in creating a small amount yellow ripple smell drifting in the wind, everyone in Gensoko is so uncomfortable right now making them tense in sighing nervously with sweatdrop and make fanning their faces. the durian hibernate&the faint yellow ripple long gone, Gensokyo return to normal expect some foods drink and plant here&there, almost everyone goes on with their normal lives as if nothing has transpired
