Blood+ One Night Kiss

_One Night Kiss_ is an action-adventure game based on the anime series
_Blood+_ created by Production I.G, set after episode 7 of the original
series. The game is set in the fictional town of Shiki-Newtown, which has
recently been terrorized by attacks from monstrous bat-like creatures called
Chiropterans.

The player controls both the anime’s main protagonist Saya Otonashi, a high-
school girl who is capable of killing the Chiropterans, and Aoyama, a
detective with the city police investigating the strange attacks. Saya wields
a katana, while Aoyama uses guns as his weapon of choice. The player switches
between the two characters automatically as the story proceeds.

Each character’s chapters are divided into adventure parts and action parts.
In adventure parts, the player walks around exploring, speaking with other
characters, and looking for information. In action parts, the player must
fight off the Chiropterans or other foes in closed-off arenas.
