She is trained in martial arts and is well-versed enough to even take down Okonogi easily, who has been training for years more than Mion has.Īlthough 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. 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. No one but the twins themselves seemed to be aware of this, and it is never brought up in the anime nor hinted. They swapped the day the oni tattoo was to be branded, resulting in the younger sister 'Shion' (Mion) becoming the next heir. 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. 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. 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 by decided to eliminate the 'competition' and keep Keiichi for herself.Due to being the next heir, Mion was branded with the oni (鬼, ogre or demon) tattoo on her back. It is revealed and very often strongly hinted that she has a crush on Maebara Keiichi, which she expresses by picking on and teasing him at every possible occasion.ĭespite Mion's wild personality, she is noticeably the only main character who does not commit murder or becomes dangerously violent ( possibly excluding Furude Rika). However, no matter how boyish she acts, she also has a girly side when opening her heart, mainly to her twin sister Sonozaki Shion. Mion is a tomboy and calls herself ' oji-san' throughout the games, manga and anime. Mion is 17, according to Higurashi no Naku Koro ni Matsuri, with a birthday in early February. The 50,000 yen that was announced as the winning prize at a game tournament is said to come from her own pocket. As the Sonozaki family is quite rich, it is obvious that Mion has a large allowance. 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 next oldest female. She is the granddaughter of the current Sonozaki head Sonozaki Oryō. As the oldest in the class, she is the Class Representative, often shortened to Class Rep.

Mion is the heir of the head of the Sonozaki family, and is the leader of the Hinamizawa School club.
