Synopsis: Yashio to Mikumo

As the old adage goes, felines may be endowed with nine lives, but what will occur once those lives run out? This tale delves into the covert realm of cats, commencing with Yashio's sacrifice of one of his own lives to spare Mikumo's. Also enclosed within Volume 1 of the manga is the one-shot Kare to Kanojo no Futoumin (彼と彼女の不冬眠).
