Yeah, it's definitely best he doesn't use full power to kill the first wave. The rest wouldn't like that very much.

he can already beat the other three on his own right now already...

1. With gravity and time his too fast for the Demon Beast Riktor and he is also stronger when he uses the gravity with his techniques

2. He can stop nearly all of the magic of Shi-anne with just using his time, though she does have some magic that can break through that but his got gravity as well

3. The Hero has the best chance of beating him, but he already knows all of the heroes abilities as well as how to stop them

4. the main reason I did not app his full power is because you had the must not be able to destroy more than a mountain for starters or something like that... but at full power the best example might be if you think of Uchiha Madara from Naruto in his prime...
Basically his range he has now is low, his normal range when we were nearing the end was more than a kilometre not counting his teleportation went from a few times to nearly infinite... also his abilities began to effect living things as well if their will was not strong enough. 
Then again he had to fight seven demon lords at the same time so he had to be OP, though he lost everyone in his team in the end...
