[Anime Crossover] Two Lifetimes, One Bond

Old, embarrassing work. Do not read. Because of his older sister, a young man from the Genji family is inexplicably summoned by the Time Government, which asks him to take over the Honmaru of a grandmother he has never met. As a materialist, the young man feels that his entire worldview has taken a massive hit. A younger brother who appears out of nowhere, eccentric colleagues, and all kinds of strange missions gradually change his life without him even realizing it. His life is like a bridge. One end is this life, and the other is the next. He travels back and forth between the two ends, forever drawn along by invisible threads of fate. No matter when, some things will never change. Other things may gradually fade with the passage of time, but as long as things turn out well, all is well. Theme:
