Asahi Grindelwald, an 18 years old nun who was sent by a religious group of Europe to oversee Aozora, Japan. Asahi was born to a German father and a Japanese mother. Asahi's father is a man of god and always does everything by God's order. Aoi grew up in such an environment. Asahi's mother is a good woman as well but is hated by her father's group due to her view on religion being loose. Asahi is a very strict nun after studying with her father's group.
