Sakurai Saki is the leader and Divine Child of the World-Bound Ultimate Bliss Church. She is described as weak, with low HP of only 7 points remaining after falling down stairs, and relies on her childhood friend Yuta for protection and support. She has a game-like system interface that the narrator refers to as the player. She possesses the skill Itchy Monster, which allows her to sense other people's negative emotions and understand their pain as naturally as breathing. She wears thick and complicated white kimono for her religious activities, which she claims is part of her weight training. She and Yuta formed the Sakura Reconnaissance Squad to scout for police badges and protect her from arrest. She is supervised by Yuta to exercise daily, and her strength increased by 1 point over a month. She has a close relationship with Fushiguro Kiyomitsu, calling him Hiro, and is comfortable enough to rub against his face subconsciously.
