Any attacks used by and on this Pokémon will never miss. They ignore evasion and accuracy modifiers, and will also hit through Bounce, Dig, Dive, Fly, and Shadow Force. If a Pokémon with No Guard is using Detect or Protect, or if a No Guard Pokémon is targeting a Pokémon using Detect or Protect, moves have 100% - X% accuracy, where X is the move's normal accuracy. In other words, any moves used would hit if they usually don't, and wouldn't hit if they usually do. This takes into account accuracy and evasion, as well as the base accuracy of the move. Moves that ignore all accuracy modifiers, including OHKOs, do not have a chance to break through.
