Dengeki Daisy , Vol. 16

After orphan Teru Kurebayashi loses her beloved older brother, she finds solace in the messages she exchanges with DAISY, an enigmatic figure who can only be reached through the cell phone her brother left her. Meanwhile, mysterious Tasuku Kurosaki always seems to be around whenever Teru needs help... Could DAISY be a lot closer than Teru thinks? Kurosaki and Teru risk their lives to activate "M's Last Testament," but a huge explosion goes off on the uninhabited island they’re on! What is the fate of Kurosaki, Teru and Akira?! The series comes to a conclusion, followed by bonus material and two Dengeki Daisy special chapters (one of which includes Teru’s late brother, Soichiro)!
