Yoshida, who worked for a black company, died in an accident.
Due to a mistake during reincarnation work, he couldn’t be reincarnated in his original world.
God suggested him to reincarnate in a different world with a mischievous angel, who unwillingly accompanied him, as his support; and the two were born into the world of sword and magic as twin brother and sister.
A few years later, Yoshida took magic lessons from his angel sister and began his special training so that he could lead a fulfilling life.
But the younger sister, who changed her mind to enjoying this world, was aiming for a parasitic life where she could live comfortably, so she continued training her brother so that she could use him well.
Being an adventurer, or the third generation of inn owners, Yoshida’s second life with a younger sister, who doesn’t wanna work, begins.
I really liked this except for:
A) I honestly think there should have been /some/ kind of romance. There is so many potential people for him to get involved with and he really doesn't with any of them.
B) The ending is too open ended for me. And there is still some stuff that I'm not sure got wrapped up. (annoyed you don't get Jessica's back story, among other things.)
Its otherwise great, there is a ton of things going on and if you can keep up with the explanations I think most of it is consistent and explained well.
