SAO : ME 1

Notes
-===-

VRMMO-RPG -
Virtual Reality Massively Multiplayer Online - Role Playing Game

Progressers -
"攻略組", or "capture/clearing group".
"Clearing" as in "clearing a game".
The author used the term directly in English/katakana, hence its usage instead of "clearing group", which is more commonly used.

WWFM -
"風林火山", Fuurinkazan's abbreviated name.
Likely Wind (Fuu), Woods (Rin), Fire (Ka), Mountain (Zan).
"As swift as the wind, as quiet as the forest, as daring as fire, and immoveable as the mountain."

NPC -
Non-Player Character.
A character not controlled by a player.

First Strike Mode -
A duel mode in SAO, where the first person to land a proper hit is the victor.

"I'll parry both sides in one motion" -
The original line used "one-action double-parry" as furigana.
As far as I know, there isn't really any such term in fencing (or anywhere else for that matter).

Flag -
A term originating from computing, for values with possible true/false options.
Used here to refer to a set of variables to bring about a certain scenario.

Ruru's Lullaby -
Romanised version:

minami kara kita tabigeinin
ryu-to katate no tabigeinin

gin no ito wo hito nadesureba
poronporori nemuri ni sasoi
nagai ohige no sonchou-san mo
gametsui bukiya no ojisan mo

hiroba de kakeru kodomora mo
yane ni nobotta kuroneko mo
koeda de utau komatori mo
tetsu no yoroi no orochi mo
torontororin minna nemuru

Original:
南からきた旅芸人
リュート片手の旅芸人

銀の糸をひと撫ですれば
ぽろんぽろりん眠りに誘い
長いおひげの村長さんも
がめつい武器屋のおじさんも

広場で駆ける子供らも
屋根に登った黒猫も
小枝で唄うこま鳥も
鉄の鎧の大蛇も
とろんとろりん皆眠り・・・
