Houtou Shigen

Shuri's closest friend, who's almost always with her, and even shares her hobby of reading perverted books. Her outfit resembles that of a witch. Her habit of saying "Awawa" has earned her the nickname "Awawa Strategist". Her name is different from the original Hotou's, as the character "Hou" is written with the kanji for "phoenix" in her name, and not "dragon".
