If you mean if its historically accurate, then no, the name wasn't given to him haha! Mori Ranmaru was just born with that name, but there were many historical depictions of these 2 having sexual relations so its half accurate? Seems like the author added their own fun twist with the soul swap! ヾ(☆▽☆)
Ohh is his name really was given to him by his lord (i mean in the origunal story)? Uwu this is cute
