Ascending the stairs and leaving the fight behind them, Yukari once more relaxed and let the conversation go back to the strange, floating "Stand" that followed Michelangelo. As a manifestation of his spirit that was controlled by his mind, it didn't seem to have a will of its own. So it was less of a summoned demon, as it wasn't really a separate entity, as it was an avatar, an embodiment of powers that were, at their core, Michelangelo's.
