Izumi's basically the mahjong expert of her friend group. While she, Nashiko, and Pai all play, Izumi's the one who actually knows what she's doing—mostly because she's been playing at family gatherings for years. She and Nashiko are close friends, and the three of them hang out together, but when it comes to the game itself, Izumi's the one who actually understands the rules and strategy.
