- Actor Allusion:
- Coupled with the largely Ryomaden-affiliated cast of the series, perhaps it is most remarkable that Fukuyama Masaharu was cast as Hiko Seijuro, Kenshin's mentor, considering that they played a quite similar relationship (as Sakamoto Ryoma [Fukuyama] and Okada Izo [Sato]) in Ryomaden.
- Cho is being played by Ryosuke Miura, known to Rider fans as Ankh. His blondness is fabulously spot on.
- Hilarious in Hindsight: As noted above, Tatsuya Fujiwara portrayed Okita Soji in NHK's Shinsengumi!, whose character became the sort-of protege of the uncouth and violent Serizawa Kamo, who Shishio was supposedly based on. In portraying Shishio, he is in a way following through.
