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.
Don't worry, Takeru! 
I'll strip down and help!
لا تقلق يا تاكيرو، سأتعرّى وأساعدك
Keine Sorge, Takeru!
Ich zieh mich aus und helfe dir!
¡Descuida, Takeru! ¡Te daré un banano!
¡Descuida, Takeru! ¡Te daré un banano!
Non preoccuparti, Takeru! 
Mi tolgo una mano e ti aiuto!
Não se preocupe, Takeru. Vou
 tirar minha roupa e ajudar!
