アーデルハイト・フォン・ベルクシュトラーセ

1st year student at St. Gabriele Academy, and third princess of Bergstrasse, a small principality in central Europe.
She is renowned for her angelic voice, which she makes good use of while singing hymns. However, it is unclear how much self-awareness she has about this.
At any rate, she is a constantly languid soul, and lacks the motivation to do much of anything.
Whenever she becomes too lazy to even walk, she incites the protagonist to carry her on his shoulders.
Her exact motives for wanting to study abroad in Japan are unknown.

"There's no point in using my full name. Just call me Aa-chan."
