Hanajima Women’s College (花島女子大学) is an elite women’s college in Tokyo, Japan.
Kana, Hoshi, and Miel are all undergraduate students at Hanajima Women’s College. Paloma’s mother is a professor of American literature there. Finn’s roommate, Honami (smoltailordolls), also attends Hanajima Women’s College.
There is a co-ed K-12 school, Hanajima Academy (花島学園), associated with the college. Ichīro and Kohaku are students there.
There is also an international co-ed K-12 school on a nearby campus, Hanajima International School (花島国際学校), where Paloma is a student.
Ichīro & Kohaku are in the same class at Hanajima Academy. Paloma is a year below them at the associated Hanajima International School.
Hanajima Women’s College & Hanajima International School is where all of the doll stories cross over. (Do the robots and fairies exist in Paloma’s and Kana’s stories? No. Does that make sense? Also no. Am I going to “fix” that worldbuilding “flaw”? Absolutely not.)
