"What do you mean, black?"
Professor Oak froze, then looked down and blanched.
The Silver Wing, which had originally been silver and glowed faintly, had now turned pitch-black.
"That's impossible! It was supposed to be silver!!"

Though their numbers were extremely small, with fewer than five discovered so far.
The strongest among them was known as the god of ocean currents and monsoons and possessed immense power.

Hardly any time had passed since then.
How could a perfectly normal Silver Wing have turned black?
Chen Shi carefully considered every possibility.
Finally, he reached a conclusion.
Something might have happened to Lugia itself, causing
