Breaking the Damage Limit

Breaking Damage's Limit (ダメージの限界突破) is a story written by Kawahara Reki that was published on one of the Dengeki Story Trading Cards, which are included with some Dengeki Bunko Magazine Volume 28 issues.

Summary
The story is about Kirito and Asuna discussing whether there is an upper limit for damage that could be taken in Sword Art Online, as traditional RPGs would have an upper limit of 9,999 damage points. During the discussion process, Kirito mentioned a number of different methods to increase the amount of damage that can be dealt at once, with the help from numerous characters. However, when Asuna asked about herself and Kirito said that her help would not be needed, Asuna stepped on his fifth toe and made him feel like he had been dealt 99,999 points of damage.
