Mion is the heir of the head of the Sonozaki family, and is the leader of the Hinamizawa School club. As the oldest in the class, she is the Class Representative, often shortened to Class Rep. She is the granddaughter of the current Sonozaki head Sonozaki Oryō. Because her mother, Sonozaki Akane, married a man from outside Hinamizawa, the heritage was passed immediately down to Mion rather than Akane, as she was the اگلے oldest female. As the Sonozaki family is quite rich, it is obvious that Mion has a large allowance. The 50,000 yen that was announced as the winning prize at a game tournament is کہا to come from her own pocket.
Mion is 17, according to Higurashi no Naku Koro ni Matsuri, with a birthday in early February.

Mion is a tomboy and calls herself "oji-san" throughout the games, manga and anime. However, no matter how boyish she acts, she also has a girly side when opening her heart, mainly to her twin sister Sonozaki Shion. It is revealed and very often strongly hinted that she has a crush on Maebara Keiichi, which she expresses سے طرف کی picking on and teasing him at every possible occasion.

Due to being the اگلے heir, Mion was branded with the oni (鬼, ogre یا demon) tattoo on her back. The tattoo is a right reserved for the oldest child and thus the heir, but Mion was actually born as the younger sister, and therefore born with the name Shion.
Mion and Shion intentionally switched places when they were young, because "Shion" (current Mion) felt it was unfair for only one of them to attend family meetings. They swapped the دن the oni tattoo was to be branded, resulting in the younger sister "Shion" (Mion) becoming the اگلے heir. No one but the twins themselves seemed to be aware of this, and it is never brought up in the عملی حکمت nor hinted.
Despite Mion's wild personality, she is noticeably the only main character who does not commit murder یا becomes dangerously violent (possibly excluding Furude Rika). However, one of the TIPS reveals that she was once driven to kill as a result of jealousy over the attention Keiichi was getting from others, which she responded to سے طرف کی decided to eliminate the "competition" and keep Keiichi for herself.
If she needs to defend herself, Mion is also the only one who does not wield a weapon—her weapons are her body and strategical mind. She is trained in martial arts and is well-versed enough to even take down Okonogi easily, who has been training for years مزید than Mion has.

Although Mion is seen using a syringe once in Onikakushi-hen, it is later revealed in Tsumihoroboshi-hen to be a black marker, which Mion was going to use to draw on Keiichi's shirt. It is کہا that the marker appeared to be a syringe because of Keiichi's paranoia and resulting hallucinations.

PersonalityEdit
Mion acts energetic and confident, often teasing her friends. As the leader of the after-school games club, she organizes various card یا board games, which she has become extremely good at, partially through cheating. She is the club member that tends to win the most, but as Rena reveals to Keiichi, she was the biggest loser at the beginning of the club. Mion designs most of the "punishment games" that the loser must perform, but, again, at the beginning, she often had to do them herself. It is a tribute to her determination that she has advanced so far in skill.
Although Mion seems very self-confident and tomboyish, it is revealed that she is quite girly. This is an important point in Watanagashi-hen and Meakashi-hen, where Keiichi decides to give a doll he won to Rena rather than Mion, thinking that she would not like girly things; in Meakashi-hen, this event is shown to trigger the development of the Hinamizawa syndrome in Shion. However in Minagoroshi-hen, Keiichi is able to resolve this fate سے طرف کی giving the doll to Mion instead (of course Mion is a little hesitant to take it, as she says, "Wh-what?! I don't like that sort of thing! I'm sharp and spunky as آپ always say!" Keiichi, however, tells her that she's still a girl to him and she ends up revealing her girly side سے طرف کی saying, "Yes, I will treasure this doll," and looking lovingly at the doll.)

As the heir to the Sonozaki family estate, she must act very formal and responsible when dealing with family matters. As a result, Mion has another side of her personality that is in complete contrast to her normal self. When she assumes this role, she becomes almost completely expressionless, and very serious. A good example of this side of her is from Meakashi-hen, where she forces Shion to rip off three of her own fingernails as punishment, despite the fact that she cares deeply for Shion and later rips off three of her own as retribution
