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.
Aoshi:(to Soujiro) How long have you been spying on me?
Soujiro: Spying? We just arrived in Kyoto this morning.
Aoshi: I see. Then it's a coincidence...Someone's been following me since this morning.
Soujiro: Oh well..um...You figured it out.
Misao: I need to know something. You're aware that Himura's fighting a battle that may decide the future of this country.
Misao: And you understand it will be dangerous for you and Himura if you can't handle the risk. Knowing that, you still want to see Himura?
Kaoru: ...If you were me...Could you travel from Tokyo to Kyoto without knowing what was at stake?
Hiko:(to Kenshin) Trying to stab a solemn sculptor in the back...What kind of monster are you?
Kaoru: Kenshin...are you mad at me for coming to Kyoto?
Kenshin: Half of me is. The other half feels somewhat...relieved.

We find out Kenshin has mastered all Hiten Mitsurugi Ryu Style techniques except for two techniques.
Seijiro Hiko is not Kenshin's master's real name, but a title given to all masters of the Hiten Mitsurugi Ryu. This Hiko is Seijiro Hiko the 13th, and he had hoped that Kenshin would become Seijiro Hiko the 14th. The first Seijiro Hiko was introduced in a Sengoku Jidai-set (pre-1600's) story, and Kenshin was created to be the antithesis, visually, of that character.
Kenshin has referred to Hiko as Shishou, which is a polite way of reffering to his master. Were Kenshin being less formal, he would have reffered to him as sensei, or teacher.
