New Light Novel License: “I Kissed my Girlfriend’s Little Sister?!”


Good day to everyone! We’re making this post to talk about one of our new licenses, “I Kissed my Girlfriend’s Little Sister?!”

From the famous author Riku Misora (currently better known for series such as “Chivalry of a Failed Knight” and others) and illustrator Sabamizore comes a rather questionable at times and engaging romantic story. Though it is categorized as a romantic story with comedic elements from time to time, do remember that this title is known for its heavy NTR elements within, and focuses on the internal struggles of the protagonist Hiromichi Satou faced with the difficult situation of, well, having an affair with his girlfriend’s little sister, who happens to be Hiromichi’s new stepsister due to some circumstances happening in the story. There is plenty of slice of life content to go around, though!

This is the series with the most amount of serious elements and dramatic developments of all the new and current ones we have. It doesn’t lack on romantic or comedic elements though, constantly keeping you interested in knowing more about the story. Nothing has been spoken about how the series ends or how it develops, so if you want to know what happens we invite you to find out by getting your hands on the series.

Currently it has 3 volumes out in Japan, with a 4th one expected soon, plus a manga series already confirmed. This is a closed series, and the story will end at the 4th volume, confirmed by the author. Tentai Books will be releasing this series with an interval of 4/5 months inbetween volumes. Digital will always be the first release, while physicals will follow a month after.

All physical editions will have a base bookmark included within the shrink-wrapped books. We will also organize a short preorder campaign with our physical editions. Those who preorder the physical edition will receive its exclusive rewards, those being special bookmarks / postcards included with the order. The preorder bookmarks will include the EXTRA LIMITED ART produced over at Japan for commercial usage. This limited art will be exclusive to our own store. No other stores will distribute this product.The preorder bonuses won’t suppose a price increase apart from the base book ONLY for preorders. Once the preorder campaign is done we will offer the possibility to add these bonuses to your orders for an extra pricing.

The first volume is intended to release at early january. We want to release it the 11th. Meaning that the 11th of February is scheduled for the physical version.

Details of the physical version:

  • Softcover
  • 210 x 148 mm
  • Will have dust jacket

*Other details will be included soon as the release date for the physical version approaches.

We will be adding the series page over at our website in coming days.

We hope you’re looking forward for this series!
