Excel Walter is a character from the Genjitsu Shugi Yuusha no Oukoku Saikenki series. She's 500 years old. She's an attractive voluptuous woman in her twenties with ankle-length blue hair that has two gold ring bands on either chest-length hair strands with bangs swept to the right side, blue eyes and a busty figure. Since her species is sea serpent, she also has antler-like protrusions on her head and a sea serpent tail. She's a very smart strategist. She's kind and wise, but dangerous yandere!
