Yankee Shota to Otaku Onee-Sanヤンキーショタとオタクおねえさん; 不良小学生和宅姐姐; 양아치 쇼타와 오타쿠 누님

Saeki Kazuko is an ordinary otaku who has a thing for "two-dimentional shota" but somehow, she is being bothered a lot by a neighbor's child named Aikawa Ryuou, an elementary school boy who looks like a Yankee but pure by heart. Even though he earnestly approaches Kazuko, he show it with honest feelings and partly some violence.
