In an alternative universe the author of this story dies. Yet in this universe, isekais can actually happen, and he soon gets transported to have a brand new life in an universe of his choice, a crossover one is chosen in the end so he can finally meet his beloveds. But along the way, many adventures, both everyday and dangerous ones comes along. To put it simply; One heck of an isekai adventure awaits. (Remake of "Is This A So Called 'Isekai'?", which before was meant to follow the story 1 to 1, but I have since changed plans for it after my interests shifting and me in general just having a different mindset about things.)
