1: In the comical Assassin's Arc of Noel's story, there are two. You must first lose to Tager. Then, you will have to fight three people. Using a Distortion Drive to finish off the first and third combatanants will result in an illustration detailing an embarrassed Noel in costume reminiscent of a certain pirate with a giant anchor and a Johnny complex, and a certain strange girl from a certain strategy game with the Guilty Gear name on Xbox 360.
2: Teach Me, Miss Litchi Episode 4, "Good Guy 1, Slacker 0" has a reference to how apparently Ragna takes more damage than he thought. Litchi tries to comfort him by saying that there are people who are weaker than him out there. A chibi silhouette of a certain super-fast ninja appears in a thought bubble, and Litchi almost says his name, though Taokaka barges in. (In the Japanese version, the name is cut off by a distant "GAUNTORETTO HAAADEEES!", as is Tager's certain body part. In the English version, they just have Taokaka barge in before the whole name is said, and Tager's body part is censored in a different way.)
