The original light novel series of the popular isekai manga!

Reincarnated in an alternate world where magic rules all, Haruto Zenfis has one goal in life: to be a lazy shut-in and watch anime all day. And he will spare no effort to achieve it. 

Thanks to his little sister Charlotte and her crew (with a bit of boost from her favorite superhero Shiva), the kingdom is saved from evil. Haruto can finally go back to plotting the best way to get expelled from school—that is, until he realizes that his meticulous plan has a blindside! 

With a new-and-improved plan in place, he must put his magical skills to the test. Volume four of the comedy-packed series by Sai Sumimori!
