Dozuki Aishi

38
Dozuki Aishi was born in 1950 to a pair of extremely wealthy parents. Dozuki's mother worked a highly-demanding job that required her to frequently travel overseas for long periods of time, which caused her to be absent for most of Dozuki's childhood. Dozuki's mother tried to compensate for her lengthy absences by spoiling her daughter as much as possible whenever she had the opportunity; she showered Dozuki with gifts and praise as often as possible, and never said "no" to anything that her daughter requested. As a result, Dozuki developed into a very spoiled young woman who was accustomed to having everything she wanted handed to her on a silver platter without ever working for it.
Like all other members of her bloodline, Dozuki is afflicted with the "Aishi Condition," a disorder which causes her to feel a perpetual sensation of emptiness, as if something crucial is missing from her life. In 1967, while attending high school, Dozuki came into physical contact with a young man whose presence could mysteriously alleviate the symptoms of her condition. Dubbing this young man her "Senpai," Dozuki was determined to turn him into her lifelong companion - however, there were other girls vying for his attention, and Dozuki had no experience with romance. It appeared as though wooing this young man would require hard work, which Dozuki was firmly opposed to.
In Japan, homes typically do not have basements due to earthquake concerns, flooding risks, and cultural preferences.
