Houtou Shigen

As a close companion to Shuri, this character shares an affinity for reading erotica and sports with her. She sports a witch-like appearance and is sometimes known as the "Awawa Strategist." Introduced later in the story, she develops feelings of jealousy when Shuri is close to Shibaki, though this resolves into a strong friendship. They now frequently share their interests and written thoughts, deepening their bond.
