Redesign of Konoko's melee profile only to be more brutal. It doesn't affect the melee profiles of other characters.
Brutal Konoko is a pumped-up version of her original AI. She makes for a capable ally or a sly enemy combatant, depending on what side you decide to script her to be on. Without performing any scripting to use this AI somewhere, the only difference you'll automatically see in Oni is the one time she is controlled by the AI in the story -- the fight with Evil Konoko in Ch. 11.
This version of Brutal Konoko is a slightly tweaked version of the Konoko in Loser's Brutal AI mod (package 21501), which makes all AIs more brutal including Konoko.
