Voice-Over Introduction
Leonardo : In the past 24 hours, I've been attacked by enemies I thought were long gone and found myself transported to a strange new world with no clue how I got there and no clue to get back and I have no idea what's become of the rest of my family. To top this perfect day off, the only ally I have in this whole mess is about to be executed. Do you think normal people ever have days like this?

Plot Synopsis
After being sent through time and space, Leonardo finds himself in Usagi Yojimbo's world.

Quotes

 * Tomoe Ame: (upon seeing Leo after his impromptu arrival in Usagi's world) Ninja scum! You shall not have him! (she promptly attacks him)

Trivia

 * At the beginning of The Real World Part 1, we see through Leonardo's point of view seconds before the events of Reality Check when Ultimate Drako appears and separates the Turtles and Splinter across time and space.
 * Leonardo ends up in the world of Stan Sakai's Usagi Yojimbo.
 * The cat-like ninja Leonardo, Gen, and Usagi fought to protect Lord Noriyuki are called "Neko Ninja". In Japanese, "Neko" literally translates to "cat".
