It was quite ironic. Just earlier today, Leonel's grandmother was warning him about the dangers of Scarlet Star Force. Her exact words were that Scarlet Star Force was one of the only Forces she knew of that could cause harm to a higher Dimensional being while even at a lower Dimensional level. However, when faced with Wise Star Order, Leonel hadn't even considered using it.
Firstly, whatever damage a Force could land required it to actually land in the first place. Leonel had no confidence in landing an attack on a Seventh Dimensional being. Wise Star Order had already proven that his mind worked even faster than Leonel's own. It was foolish to even consider such a thing.
Secondly, Leonel had still underestimated his own Innate Node. Even though he remembered the words his grandmother had said, he didn't think that this would apply across two Dimensional levels.
