This article contains mature themes and spoilers for the game Neko Kawaigari!. Proceed with care! 

Umi and Nami Asou (浅生 海、& 浅生 波 Asou Umi & Asou Nami) are heroines in the eroge visual novel Neko Kawaigari!. They are tortoiseshell nekomimis, who suffer from severe palpitation and therefore have to reside in a hospital, where the story of the visual novel takes place at. Both are voiced by Asari.

About
A pair of twin patients who may not be distinguished from each other at first glance, their only difference being the colors of their tails (Nami's is brown with a white tip, Umi's is white with a brown tip). They are exactly alike in personality and almost synchronized in voice and motion, often speaking in synch or finishing each other's sentences. They are innocent, active, mischievous, and the principle of kittens themselves. Umi and Nami serve as the hospital's mascots.

Umi wants nothing more than Nami's approval and devotion, but Nami's eagerness to be self-reliant can lead to a power struggle between them. While not as mature as Nami, Umi can be just as stubborn when she decides upon something, and is more than capable of matching her sister when it comes to arguments and disagreements.

Nami is the more outgoing of the siblings - Nami shares Umi's playful, demanding demeanor, constantly requiring attention and affection. While she loves Umi unquestionably, she also longs for independence, to be seen as her own person instead of one half of a pair.

Though unaware of their heat cycle, they do illicit things with each other. This doesn't improve their condition, however.

Story
