Nana Akasaka is a character in the Girls Bravo Manga Series.

In Act. 42, Koyomi Hare Nanaka finds a letter addressed to Nana and wants to find her so she can give her the letter. In the next act, Koyomi finds Nana and finds that the letter was written by Nana's deceased grandmother. The letter reads that Nana's grandmother was sorry the kimono she made for her wasn't how she wanted it and promised that next year they'd find a better kimono. Nana is sad that her grandmother is dead, but is happy when Koyomi muses that her grandmother is still watching her from the afterlife.
