Just read the Hokage world arc. The other parts have all been scrapped, but since they can't be deleted, they've been reuploaded in a new volume: the Hokage World arc.
The protagonist of this book can freely travel through countless worlds and meet mature older women. He isn't the sort who transmigrates and immediately works hard to grow stronger and conquer the world. This is a lighthearted story. Whenever something bad happens to the protagonist, he steps in. For the most part, it's about living an easygoing life with the older sisters across countless worlds, and meeting even more of them.
