Spontaneous combustion like what happened with Shishio is impossible. If his body temperature was rendered unnaturally higher, his brain should have boiled in it's skull.
Kenshin forgot to tell his Master where the Aoiya was (like he couldn't follow the swath of destruction and find it... -ed.).
In this episode, they chose a different voice actor for Seta Soujiro.
The black tattoo marks around Anji's eyes are from Tsubaki's ashes.
Saito was never wearing the uniform hat, it was just the light from the explosion and shading of the drawing.
When Shishio fires the Armstrong cannon at Saito, Kenshin, and Sano, notice that in the still shot of Kenshin and Saito dodging the blast, the uniform hat of Saito's police officer attire appears (it is not present before or after this shot).
After Misao and the rest of the Oniwaban group make their appearance on the rooftop, it shows Kaoru and Yahiko. Yahiko's skin color has faded to match the skin color of the villagers.
Sano's headband turns purple because of the lighting.
While talking to Kenshin, Saito's "toothpick" is smoking.
While punching Kenshin, Sano's ribbon turns purple.
Juppongatana Roll Call
Elder Saizuchi, the short bald guy with the four whiskers, and his partner, Fuji, the giant who is only seen by his feet, are not mentioned in the roll call, although they are included in the group.
Chou is not able to attend.
Adding to the other point, the cigarette he has turns into a toothpick, than back and it is smoking, and then back into a smoking toothpick. Saitoh is smoking a toothpick.
In the CN dub of this episode, Saito's cigarette is replaced with a toothpick, but for a brief scene, the toothpick is a cigarette (they didn't edit the scene like they normally would).
The closing song goes back to T.M. Revolution's Heart of Sword ~Before Day Break~.

7. Migi Kiriage

Kuzu Ryu Sen means nine head dragon flash when the kanji is directly translated. So, the attack means nine-headed dragon flash in English.
Juppongatana - East Members
Anji - the guy who met and trained Sanosuke in a previous episode.
Hennya - the guy with the dark red spiky hair and bottom part of his face covered, with two scroll sheets with writing spread over his shoulders.
Iwanbou - the grinning pink chubby guy with the palm tree looking hairdo
Hiko Seijiro reveals he's 43 years old. Yahiko says Kenshin is 28 years old. Misao is 16.
The cape that Hiko wears was inspired by the title character of the American comic "Spawn". In volume 12 of the manga, it is stated that the cape has counter weights which applies roughly 37.5 kg of force to the soulders of all the masters of Hiten Mitsurugi Ryu, thus keeping their immence power in check during times of peace.
When Kenshin does a Ryu Sho Sen to defeat Senkaku he uses his left hand to push on the back of his blade. This would be okay with an ordinary sword, but with a sakabatou (reverse bladed sword) he would cut his hand.
