Bakemonogatari manga volume 22 features story by Nisioisin and art by Oh! Great.

The moment Koyomi's been waiting for is finally here! But as his date with Hitagi concludes, so does his story, followed by the stories of those he's saved since that fateful spring break.

Though this monster's tale has reached its end, that doesn't mean they're gone—because monsters have been here since the beginning.
They always have.
They're everywhere.
