Yes, while Neku took a hands on approach, Yamato is going to lurk out of range. He honestly felt like he'd been smacked around with a sledgehammer, so the less physical fighting he had to do, the better.

Of course, that didn't mean he was going to let Neku fend for himself. As soon as the other darted out of the way of the stingers, Yamato delivered a powerful Judgement attack on the swarm. He only had enough energy to cast maybe two more Judgements before having to resort to using his Persona.
