Nekomonogatari Noir Blu-ray (Manga Entertainment UK)

This is a story of a human who plays a forbidden game towards becoming a monster.

It's the beginning of Golden Week and Koyomi Araragi has more to deal with than discerning his feelings for the ever-enigmatic class president, Tsubasa Hanekawa. A monster is afoot attacking individuals at the dead of night and zapping them of their energy. The cause? A cursed cat and the student president herself, but the solution to the problem might be far more complicated than expected.

The prequel to Bakemonogatari, Nekomonogatari Black will uncover the nightmarish nine days that were once sealed off and hidden by Koyomi and Tsubasa themselves.
