Pixiv Title: キリトがくれた装備
Pixiv Commentary:
シリカ「キリトさん、こ、これ・・・」
キリト「気付いた？そう、旧スクなんだ！素材を集めるのに苦労したよ
　　　　あ、白の方が良かった？そっちも作ってあるよ。」
シリカ「あの・・・」
キリト「心配しなくても大丈夫、今の攻略レベルの限界まで強化してあるから
　　　　でも、茅場晶彦もわかってるよなー。まさかあのクエストで（ry」

シリカ「・・・」

I'm afraid I'm not clear on what Kirito's implying in the last line since I only watched SAO for Silica's episode.

Title: The equipment from Kirito
Commentary:
Silica: Kirito-san, th-this...
Kirito: You noticed? That's right, it's an old swimsuit! The materials took quite some trouble to gather. Ah, would white be better? I've also got that made.
Silica: Um...
Kirito: You don't need to worry, it's been enhanced up to the current level limit. But to think Kayaba Akihiko also knew about this... (implies something about "that quest" without elaborating)
Silica: ...

Kayaba Akihiko!!! G.J!

Presumably 'this' is the school swimsuit fetish. Dunno what quest he might be referring to though.
