Mobile Boyfriend

High school student Ayumi kills herself and leaves behind a cryptic message that says "will be killed by boyfriend." Ayumi's classmates Satomi and Yuka investigates her suicide and quickly links her death to a cellphone dating simulation game called "Keitai Kareshi." The game distributed by popular mobile gaming site "I-Scream" allows players to pick avatars and exchange messages with a virtual boyfriend. A love gauge determines how well the player is going. Satomi then downloads Ayumi's cellphone boyfriend Riku, which her co-worker Eri also downloads onto her cellphone. Soon after, Eri dies from electrocution - not long after the love gauge on her cellphone hit zero. Yuka also downloaded cellphone boyfriend Masaya, which Satomi sends to her manager Ishikawa in an attempt to save her. The next day, Ishikawa dies from a mysterious accident. The mystery deepens as Satomi discovers the image of Naoto, a senior student whom Satomi secretly admired, on her friend Hisami's cellphone.
