This was a fantastic little collection. Even if it took me longer than anticipated to actually read it, I still can say I thoroughly enjoyed every story in here. Not all of them were great or top-notch, but they were all incredibly enjoyable and far from being bad. If you, like I, had become familiar with the character through more modern media, like Lupin III, Netflix's Lupin, or Persona 5, this is definitely a must-check out. I fully intend to read more if I'm able to, though the library system by me only has this, it seems. Fortunately, a good number of the stories are already in the public domain, so I can read them that way, I hope.
