Fragments Blue

One summer day, a young man named Kaname Ōsaka receives a letter with no return address. "If you remember where I fell, go there with Momoka and search." The letter includes a small key, and is signed by Chika Yazawa, Kaname's childhood friend and Momoka's sister. However, Chika had died two years earlier when no donor could be found for a heart transplant. Kaname and Momoka, along with their friend Natsune, have no idea what the letter means, but decide they must investigate.

Fragments Blue is a mystery-themed visual novel with light investigation elements. The player takes the role of Kaname who, along with his two cute female friends, goes to investigate the circumstances surrounding the strange letter he received. The story proceeds with lightly-animated illustrations and fully-voiced dialogue, and at certain points the player must choose from multiple responses, which determine the direction of the story and lead to different endings.

As the story proceeds, the player collects various pieces of information, which are collected in an in-game log and can be reviewed at any time. Certain events may require the player to select one or two pieces of information as evidence, and the resulting conclusions will also change the path of the story.
