テレビの消えた日

The time is twelve years ago.
A comet of unprecedented proportions appeared in our Solar System.
Its magnetic field was such that when the comet drew closer to Earth, it interrupted radio waves worldwide.
That time was nicknamed "The Day Television Disappeared".
The day the world lost its signal, our protagonist, Mimasaka Shingo, lost his parents.
At the heart of this incident is his father's former boss, Hosaka Kenichi, on whom our protagonist who knows the truth has sworn revenge.

Twelve years later, Shingo meets Hosaka Nanami, a highschool student. Forlorn memories connect and bind, in their cement the truth. Hosaka Nanami is… Hosaka Kenichi's daughter.
Shingo thus decided to make her life a living hell. Perhaps, when his loved ones are ripped and grinded to pieces, that man might know the misery he once taught others.
