Leonel had indeed been stalling. He needed to take the initiative so that the morale of Earth could be as high as possible, that was why he had acted so recklessly. Thankfully, due to the chaos of the current battlefield, all of which was taking place on a singular ten kilometer long ship, it was harder for them to actually pay attention to what was going on in Leonel's battle. This was especially so since Leonel and the five Heads were still on the roof of the ship while many of the other battles had begun within the ship itself.
Leonel was trying not to move right now because this inaction would cost him the least amount of Vital Star Force. If he went all out, he could last in this state for three to five minutes max. If he added the supplementation of the Segmented Cube into the mix, he could last about half an hour.
