What does Touma say to the "Replica" Sorcerer with the Obsidian Blade?


At the end of _A Certain Magical Index I_ episode 18, the "Replica" Sorcerer
(the one with the Obsidian Blade) asks Touma to make sure he protects Misaka.
When Touma answers, we can only see his lips moving (no sound) and then he
smiles.

Misaka is listening from behind one of the iron beams of course. Normally in
anime, it is fairly clear to me what these moments signify, but in this case,
both the Sorcerer's and Misaka's responses are (in my opinion) ambiguous.

What does he say?




> “I have promised to protect Mikoto and her around.”

When Touma helped Kuroko, he said so, in Volume 8 of the original novel. And
perhaps in Volume 11 of the manga.

Manga volume 11, chapter 64, page 15

The full quote was:

> "That’s right, it's a promise. This promise is to protect Misaka Mikoto and
> the world around her. This is my agreement with a certain nameless person
> who fell in love with her so quickly."

He explains this to Shirai Kuroko regarding his promise with Etzali from
_Toaru Majutsu no Index_ light novel volume 08.
