This episode aired the week right before episode 45 was aired.
In this episode, Kaoru and Yahiko were plushies. This special has two parts. In the first part of the special, they had a very basic summary of Kenshin (who he was and how he came to be in Tokyo with Kaoru and the gang).
In the second part of the special, "Himura Kenshin’s Greatest Hits" they show him using his Hiten Mitsurugi Ryuu moves on various opponents, though it doesn’t go into detail of how they work like the "Special Techniques" special.
