Set to be published on 10 April is My Little Sister Can’t Be This Cute and Brush Up on Middle School English by Chukei Publishing.

As the name suggests, this book lets students bone up on the required English curriculum set to the backdrop of the My Little Sister Can’t Be This Cute popular series of erotic game (eroge) otaku themed light novels. Yes, someone actually made this.

For those unfamiliar with the series, it follows the lives of 17-year-old Kyosuke and his younger sister Kirino. The two maintained a somewhat distant relationship until Kyosuke finds that Kirino is actually into eroge (erotic video games).

Finding common ground in the hobby of adult-oriented, occasionally homo-erotic and incestual computer games they share a renewed family bond and also forge friendships with others in their community.

The textbook covers 23 units such as imperative sentences, conjunctions, and relative pronouns. Youngsters can also learn through dialog from the hit light novels such as “My little sister likes eroge” and “Kyosuke is the only one who can help Kirino.”

Younger sis Kirino also guides you through the chapters chiding you into better English. It can’t get more tsundere than that.

Tying education into a pop culture is a proven way to hold kids’ attention, and sentences like the ones above probably have enough impact to help memorization of vocabulary and sentences structures.

On the other hand, I can overlook the causal references to taboo topics such as incest, but for the love of god, can’t they stop polluting our children’s minds with overused Japanese-English loan words like “goods” that we rarely say.

“These are her things!” Or, if they want to inject a little more edge in this textbook, go with “This is her sh*t.”

My Little Sister Can’t Be This Cute and Brush Up on Middle School English goes on sale 10 April. Preorders can be made on Amazon Japan for 1,470 yen (US$16).
