Toriko no Shimai ~Midara ni Moteasobareru Unmei no Mayoigo~

Touya Misaki is a student at the prestigious Aigaoka Academy. Orphaned young, she was adopted by a kind couple and now lives happily with her childhood friends, the Uryuu sisters Kazuho and Futaba. Yet, one longing haunts her: her twin sister Hyouka, adopted by another family before her. Misaki believes Hyouka is happy and plans to find her when able. But the reunion happens sooner than expected. A transfer student arrives—Hyouka herself. While Misaki is overjoyed, Hyouka seems uneasy. Suspicious, Misaki investigates Hyouka's foster father, the president of Kijima System, a company with shady dealings. Her fears prove right: beneath the surface lies a dark, twisted truth that shatters her world.
