Spoiler for GGO Chapter 7 Volume 5:

Sinon opened her mouth and a small voice asked.

"You are this strong. What are you afraid of?"

Then she saw the eyes of Kirito momentarily shake. After a brief silence, Kirito answered as if he was enduring something.

"This is not strength. Just skill."

At the moment she heard those words, Sinon forgot about the blade of light next to her throat and shook her head violently.

"Lies. You lie. If it was just technique, it would not be possible to cut Hecate's bullet. You should know. How did you become this strong? I... I want to know that so..."

"Then let me ask you!"

Kirito suddenly interrupted her in a low voice, but with blue flame like heat mixed in his voice.

"If that gun's bullet will really kill the real world player... And then, if you do not kill, either you, or someone important to you will be killed. If that is the case, would YOU. PULL. THE. TRIGGER!?"

"...!"

Sinon forgot to breathe, and her eyes widened.

Does he know? she thought that for a moment. The mysterious visitor, did he know that Sinon's past was paint in darkness, and an incident happened?

'- No, wrong. It's not like that. Probably... this person as well, in the past...'

The left hand supporting Sinon's back became hard with tension, but soon relaxed. While his hair touched Sinon's forehead, Kirito shook his head and whispered;

"...I can no longer do that. That's why I am not strong. I... cut two people at that time, no, three people, and I do not even know their real names... I just closed my eyes, plugged my ears, and pretended to forget everything..."

So Kirito thinks he's weak because he can't kill anymore? Doesn't he like this new way of thinking? He imposed it on other people before.
