Volume 1

Volume 1 is the first volume of the Nyankees manga.

Summary
Ryuusei is looking for a male calico with a scarred eye. He wanders into Nekonaki territory looking for food and meets the local strays. They get in a spat over Ryuusei disregarding the rules and it eventually involves their boss, Taiga. Ryuusei finds Mii, a female cat and tries hitting on her. This breaks one of the local laws, Article 42 that prohibits sexual relationships. Ryuusei openly objects to the idea of having rules as a stray cat and fights Taiga over it. Ryuusei displays a form of power none of the other cats have witnessed before. After winning the fight, Ryuusei finds a box to sleep in.

He is disturbed by two members of Goblin Cat Tails, a rival gang to Nekonaki. Most Goblin Cat Tails have long fur, their two strongest members are twin two-tone cats named Kinbi and Ginbi. The only way to tell them apart is in human form, their piercings are on opposite sides. Ryuusei is stuck in his box and is knocked around by Kinbi and Ginbi when Taiga arrives to defend Ryuusei and inform him that he is the new boss of Nekonaki. Watching Taiga fight, Ryuusei determines Taiga is a good leader and should remain the boss of Nekonaki. Ryuusei and Taiga are an effective team against the Goblin Cat Tails and drives them off temporarily.

After the fight, Madara, a tortie tom, returns and reveals that the male calico Ryuusei is hunting is actually the leader of Goblin Cat Tails. Afterward, Mii is abducted by Kinbi and Ginbi. The Nekonaki rally together with Ryuusei to find her, but most of the cats get distracted along the way. Only Taiga and Ryuusei make it to Goblin Cat Tails territory to find her being held captive.

The boss of Goblin Cat Tails chastises his gang for capturing a female cat for seemingly no reason when Taiga and Ryuusei arrive.
