Neptune

is the home of Natsumi Date located towards the bottom of the Kanashii ocean. It serves as her haven from the bounty hunters that seek to claim her head as their own to collect the plentiful bounty placed upon her head. In actuality, very few have ventured into the depths of her domain, due to its location. Despite knowing that her home is in the Kanashii ocean, where it is exactly is an answer only Natsumi can truly answer. Many have spent years searching for the house, but very few have been able to find it. However, even if one does find it, they have no means of getting there without nearly killing themselves. Natsumi's home is at the bottom of the ocean—nearly ten thousand feet underwater—and the water pressure there is immense. By using the strength of her spider-webs, she is able to survive these incalculable pressures.
