Owarimonogatari

"Owarimonogatari" (終物語), also known as "End Tale," is the twelfth part of the "Monogatari Series," comprising three volumes: "Ougi Formula," "Sodachi Riddle," and "Sodachi Lost." The story follows Koyomi Araragi's encounter with the mysterious transfer student Ougi Oshino and his investigation into a non-existent room at school. This leads Araragi to revisit his dark past from middle school, including conflicts with classmates and a cheating accusation. The narrative delves into Araragi's past and his reasons for becoming reclusive before high school. "Owarimonogatari" also includes chapters such as "Shinobu Mail," "Mayoi Hell," "Hitagi Rendezvous," and "Ougi Dark," each detailing Araragi's encounters with different characters and his ultimate confrontation with his past and "the enemy." The anime adaptation by SHAFT was aired in two parts, with the first part in 2015, adapting the first two volumes, and the second part in 2017, adapting the third volume. It is followed by "Zoku Owarimonogatari," which recounts Araragi's adventures in a mirror world after graduation.
