Эп. 17: Сатоши извиняется перед Шинон и просит её заботиться о Сатоко во время фестиваля Ватанагаси.

17

Satoshi apologizes to Shion (still pretending to be Mion), and asks her to care for Satoko during the Watanagashi festival, and presumably murders his aunt the night of the festival for abusing Satoko. Shion is suspicious that he is the culprit, but provides an alibi for him when detective Oishi questions him. In the process she reveals that she isn't Mion, but her twin sister Shion. Shion's family finds her when Oishi checks out her story, and she is taken back to their family estate to answer to her grandmother for the trouble she has caused. There, in the underground torture chamber, she insults the family name by proclaiming her love for Satoshi. Mion orders her to ask for forgiveness for what she has done and that Kasai and their uncle, who reside in the next room, will be spared. Shion submits, and Mion takes out a de-nailing torture device. Shion is forced to de-nail herself for her crimes against the family, but can only de-nail her left pinky nail. Sonozaki henchmen step in and de-nail the rest of her left ring and middle finger nails for her. The following day Oishi meets her at the toy store where she finds out that Satoshi got the toy for Satako, and takes her into the station for question. He explains that the previous day, Satoshi has gone missing and Kasai explains they have caught the aunt's murderer, a cocaine addict. (Source: Wikipedia)
