Kemono na Watashi to Yoimasen ka?

Synopsis

Tomo-kun, an office worker, is neighbors with Aki-san. Aki often comes over to Tomo's house to drink alcohol with him, but when she gets drunk her secret is revealed, she's actually... part cat! As Tomo-kun continues his life, other part-animal Oneesans will come to drink with him. (Source: Takeshobo, translated)
