There’s a bonus story unrelated to the main story line left in volume 11 about a maid in Wendelin’s mansion. I have no particular interest in translating it, so I’m skipping it.
Next week Volume 12 will start. Chapters 1 and 2 are rather short (2 or 3 parts each). Chapter 3 is by far the longest chapter of the entire series so far. Look forward to it or read ahead here.
