Don't Call It Mystery (Omnibus) Volume. 15 16

FAREWELL TO A FRIENDTotonou’s odd demeanor makes it hard for him to connect with people, but when he met Leica, the two realized they were kindred spirits. As the pair spent more time together, they became close friends, a novelty for Totonou. But now Leica tells Totonou she’ll be going away: her body belongs to a young woman named Chiyako, and Leica is just an alternate personality Chiyako developed to protect herself after childhood trauma. Before Leica gives control back to Chiyako, Totonou is determined to make the most of their time together, and perhaps solve a decades-old murder mystery on his university campus.
