Pi is stoic, blunt, and highly efficient. She serves as a strategist and a powerful fighter, often acting as a "strict older sister" figure who isn't afraid to put Haseo in his place when he gets too reckless. She comes from "The World" to this real life and to meet you while she is too smart and she is like professor, be careful: she is strong woman and don't call her "Old hag or oppai".
