Is that really a question? You start the game with it. Along with widesword L. Longsword L you have to earn from a Swordy.
Longsword Is and Ls are available from Swordy viruses in the Sci-Lab Areas.
By having a longsword E . . . and then GIVING it to her. Longsword E is in a blue mysterydata in the ACDC area. You should have already found it. If you decided to put it in a chip trader . . . well then you're really screwed, aren't you. You may be able to get it back via Higsby's OrderSystem, or you might have to just fight a lot of Swordys in Sci-Lab 1 to get another.
