Tokidoki Bosotto Rossiya-go de Dereru Tonari no Alya-san

Masanori Kuse, a young Japanese high school student, is bilingual: he understands both Japanese and Russian equally well. So the day Alya, a pretty silver-haired Russian student, is transferred to their class, he is the only one who can understand her when she speaks in her native language. On the surface, Alya is a polite and smiling girl, which has made her very popular with the other students. But when she speaks in Russian, she takes the opportunity to say everything she really thinks, and she is far from being so amiable then!
