The minute Ojama Knight is fusion summoned onto the field, it activates and you must select up to 2 monster zones. If your opponent has all 5 monster zone taken up, you cannot select any of these monster zones. If 2 of their monsters get taken out of the field after the Ojama Knight has been summoned and already activate it's effect, your opponent can still summon another 2 monsters into that area.
But if your opponent controls 4 monsters when you fusion summoned Ojama Knight, and you select 1 of their monster zones, as long as Ojama Knight remains on the field, that 1 monster zone cannot be used.

Then at the end of the damage step, the monster will go to the graveyard and the opponent will be dealt a further 1800 damage from your monster's effect.
The damage is equal to the monster's ATK, with all bonuses and penalties applied.
