Producing Errors

----

"Three such enemies?" Apollo muttered to himself. Just a single exceptional puppet was enough to give him a headache, if he had to deal with three of them simultaneously, a headache would be the least of his worries. On top of this, it would only worsen if each of them possessed unique special abilities. 

As a result, Apollo began to entertain the idea of summoning his Demons. As of now, he had gained enough combat experience to justify this idea. Furthermore, he also gained insight into fusion techniques. Just this alone was enough to speak volumes of his benefits.

However, the thought of summoning his Demons stimulated another string of questions he kept hidden in his mind, 'If I summon Fuhrer and the rest, will the difficulty increase accordingly? So far, the difficulty has scaled in light of a talented opponent. But, if I introduced allies, then this might turn into a different story altogether.'
