Stargazing: Yokan - Masumi Ito
I personally never got into Red Data Girl. It started off with an interesting premise of a sheltered shrine maiden who is cursed to basically be a walking EMP. Despite these hindrances, she starts going to a public school, under the watchful eye of a not-so-friendly guardian.
The premise changed almost entirely by the end. The one consistency I enjoyed was the traditional Japanese atmosphere, and nothing encapsulated that better than Red Data Girl's ending theme. It just feels so traditional, but not outdated.
