Higurashi no Naku Koro ni

Synopsis

Shion believes the Sonozaki family is connected to the acts of spiriting away people in the village, especially in the case of Satoshi. Enraged, she tasers and imprisons Mion in the dungeon and unintentionally kills her grandmother after tasering her as well, dumping her body down a well used for corpse disposal in front of Mion, repeatedly accusing Mion of having been implicit in Satoshi's murder. Shion pretends to be Mion the next day and confronts Keiichi about the previous night's encounters, which Keiichi still denies. Posing as Mion, she attends a village council meeting and lures the village head to the estate, and tasers and captures him after he reveals that her Distinction (when she had her fingernails removed) was so she Kasai, her uncle, and Shion herself would not be killed, confirming for Shion that Mion and her grandmother did have Satoshi killed. (Source: Wikipedia)
