The Sword in Daimakaimura does more damage than most weapons, but it is not a projectile. Beating Ohme (オーム), the boss of stage 4, looks like it would be impossible with the Sword. See video of the boss here: https://www.youtube.com/watch?v=hM_D7BkxU7A
Ohme seems to be inspired by the Ohmu in Nausicaa.
Well, I'm more used to a sword... It's fine. It'll work outDon't be unreasonable!
What do you plan to do about Ohme?!Wa... wait Kirito, why did you take the sword?
