The Magic Comes Back/Playing With

Basic Trope: After a long time of lack of anything supernatural in the world, things fantastic slowly (or suddenly) reappear.

Straight: Youkai sighted in the abandoned buildings in Tokyo. Some people begin to be able to bend elements to their will.
Exaggerated: Hundreds of Youkai marching in the modern streets of Tokyo. Significant chunk of the population suddenly capable of flight and mind control and hurling fireballs.
Downplayed: Rumours of working spells floating around in the internet. Those spells might actually work given certain (complicated) conditions. There seems to be more and more of them appearing everyday.
Justified: Magic in the world has its ups and downs, it's currently going up after a long downtime.
- The ward that seal the deity of magic is weakening, and his/her power begin to seep into the world.
- Magic is an immune system of the world, and it has been dormant due to lack of serious threat. The return of magic means that an Eldritch Abomination will soon menace the world...
Inverted: The Magic Goes Away.
Subverted: Youkai sighted in the abandoned buildings in Tokyo. These are actually mutants.
Double Subverted: Mutants which creation require the work of spells, which is only possible due to magic returning.
Parodied: Magic is returning, and people promptly exploit it for doing crazy sex. Bye bye fursuit, welcome... umm... the real thing.
Zig Zagged: Magic seems to have its own cycle, sometimes it's returning and sometimes it's leaving.
Averted: Magic has always been there, it's just not many people can endure the training to even have rudimentary capability of it.
Enforced: Easy way to give people super power and have battle with magical monsters from ancient times.
Lampshaded: "It's the best of times, man... soon we will be able to bend reality at our whims."
Invoked: Bob stocks up occult books, believing that it will give him head start in the new magical era.
Exploited: The government immediately recruit anyone capable of magic, for the new era of magical warfare will soon dawn.
Defied: Upon the first signs of magic returning, some particularly determined people (whose intention might be malevolent or benign) reinforce the seal on the deity of magic.
Discussed:

Bob: "More freaks make their way to the headline. I wonder what's going on in the world."
Alice: "My spiritual sense tell me that magic is returning to the world, and that we'll see even more fantastic things soon."
Bob: "Well, I always want a Catgirl as a girlfriend..."

Conversed:

Bob: "Hey Dave, what would you do if one day, magic suddenly exist in the world?"
Dave: "Why Bob, of course I'll use spells to get all da bitches."
Bob: "How is that different from what you've always been doing?"

Deconstructed: The magical beings promptly slaughter the magic-less humans, and make this world their own.
Reconstructed: Humans fight back those magical beings, with spells they hastily learned.
Played For Drama: The harrowing tale of a few survivors fighting to escape from a metropolis overrun with unicorns, hydras, dragons, etc.

Go back and feel The Magic, man!
