Both. The Conveyor Belt On Map Event/Battle Sprites would include it on the party as another way to easily extract mana and the enemies would be sporting their own versions (though in this case more synthetic vs magic) in events with Selena/sprites.
Currently, there is only plans on the Conveyor Belt On Map Event and some of the side events with Selena (Solo character images vs group game overs). I'm not sure I will be including it with every single enemy that appears on this map and instead focus on specific occurrences.
