Katie's Lullaby

Aito Minasuki thinks that his high school years were to be of the ordinary kind: tests, studying, friends, stress, and perhaps even a girl to hold hands with to school. However, that all changes once he involves himself in the tricky spiral wiring of a headless student one morning, and the problem is: no one has any idea whether it was a murder or a suicide.

Ayane Misaki, his supposed childhood friend, drowns him deep into the mystery, and it isn't long until he realizes that the further he delves into understanding more about the case, the more bizarre it gets. Their only lead is a footprint, and the shoe size exacts Nuyron, a team of scientific research.

The company has proven to the world countless times that it does not carry aliens and the truth of the said mystery, but as information unfolds, Aito finds more about himself than the reality about the other side. Especially when a being from the other side falls in love with him, capturing him, and bringing a halt to his investigation.

Aito Minasuki hit his head, and he hasn't any idea that the truth behind it all is within his memories: memories he cannot touch when blinded. The conundrum of the killings. The puzzle of friendship. The obsession of secret. Intergalactic beings being similar to humans?

It's a lot much harder when you're confused by the truth.
