Kanpai!
 Kanpai! or Kimi no Unaji ni Kanpai! (キミのうなじに乾杯! lit. A Toast to Your Nape!) is a Japanese manga by Maki Murakami which has been licensed and is currently being published in English by TOKYOPOP. Although Kanpai! is the title officially acknowledged by TOKYOPOP and used on the covers and the TOKYOPOP title page (as opposed to the original title page by Murakami which is also used) only kimi no unaji ni kanpai! is used in the book itself in all other instances.
