Kannazuki Yukariko no Yuuga na Himatsubushi

A gorgeous beauty of unknown age, Kannazuki Yukariko, who lives in a super mansion in the middle of Roppongi.
She loves graceful and beautiful things from the bottom of her heart, and she will never forgive ugly and boring things,
or things that interfere with her enjoyment-- Ms. Kannazuki's oversized "killing time" begins!

Wherever she goes with her motto of living gracefully, a storm is inevitable!!

A suspicious man trying to remove the cord (of a baby carrier) of a mother holding a baby in the city.
Ms Kannazuki who happened to notice the incident swiftly stopped the man by screaming at him.
When Yukariko returned to the gorgeous Western-style building where she lived,
a boy named Inori Mashiro, who had lost all of his relatives, came to her for help?!
