Amato Takeru, a high school student, has just moved to Akihabara. He's chosen a house with cheap rent, but with one particular imperfection: a hole in the living room floor. When he peeks into it, a girl pops out... And so begins the hectic life of Takeru and the cat Eto-musume, Nya-tan.
I'll come at you for real 
this time, Nya-tan.
سأفعلُها بكِ فعلاً هذه المرّة يا نيا-تان
Dieses Mal ist es ernst, Nya-tan.
Esta vez atacaré en serio, Nya-tan.
Esta vez atacaré en serio, Nya-tan.
Désormais,
je ne me retiendrai plus.
Questa volta ti colpirò davvero, Nya-tan.
Eu vou te pegar de jeito dessa vez, Nya-tan.
