Am I Actually the Strongest? 4

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 a 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!
