Rumiko Takahashi owns Ranma 1/2.
A great pressure surged down upon him, pushing it off to the side the martial artist leapt towards the enemy as the road next to him cratered under the shifted pressure. Dodging under a ripple in the air the martial artist frowned at he realized the enemy well and truly had him on the ropes. Ranma could do little in this battle, the enemy, which appeared similar to an elf - although taller than a man - was in control of the fight, its ability to manifest it's will into reality was horrifying and rendered it near unstoppable. Only Ranma's own pitifully undeveloped will was able to shift the enemies away from himself, but even then it was useless on the offense.
The creature was looking more furious now, it's inhumanly beautiful face twisted into rage. "Die Human!" Ranma felt the pressure of the enemies will again as it buffeted him in an attempt to rip his body to pieces. Crying out in agony as his part of his body began to obey the enemies will Ranma summoned his flagging strength and forced it away from him.
A nearby post box twisted out of shape and then burst into shards as torn paper littered the ground where it had been.
Panting Ranma sprinted as fast as he could around a street corner and ducked into an alley, hiding in the shadows he applied his father's sealed invisibility technique and relaxed, leaning into the wall. There was nothing he could do right now to defend from that creature... he needed time to prepare. Time that Ranma had to spare, now that everyone else he knew was dead. Crying bitter tears Ranma Saotome slunk away, biding his time until he was strong enough to take revenge… because there truly was nothing else left.
A bird that was high in the sky above the concealed boy would have seen the albino human looking creature scream in rage and destroy everything in a twenty meter radius. But the creatures took pleasure in practicing their will against moving targets, and so there was no bird.
A satellite that was zoomed in close enough would have seen Tokyo as a nearly destroyed city, great tracts of land nothing but rubble while others mere meters away stood untouched, not being interesting enough to fight over yet.
If the satellite was looking a bit wider, it would have seen all of Japans & China's cities in a similar set of straights, despite their being no evidence of destruction outside the cities…
But that would come; after all… you can only kill so many people in a single place before getting bored with it.
