PK: What do you mean- wha?????

PK realized he was in purple attire. He had purple attire and his hair color changed to purple. In addition, his hat became a fedora.

PK: H- how did I even get this form?

Mokou: It seems like the Barrier liked your initiative of holding off the beams from its destruction so it gave you this form.

PK: ...WELL THAT SEEMS LOGICAL!!!! NOW I CAN DEFEAT THE ENEMIES WITH EASE! Wait, is the mission done yet?

Mokou: I'm afraid not. I got intel that the enemy's gonna return soon. So I have to make you stay to fight.

PK: Well that's okay! I have this form now!

Mokou: Speak of the devil, here they come!

Grunts: WE WILL DESTROY THE BARRIER FOR LADY VIVIT!

PK: ViVIT? Where have I heard that name before?

Mokou: Fire all danmaku!

Danmaku was fired at the grunts but they dodged them.

Grunt #1: We'll show you why we are more advanced than you guys!

The grunts started to change into robots. Not small ones, but like huge gigantic Mecha.

Mecha #1: TARGETING BARRIER.

The Mecha started to fire laser beams that was the size of a building at the barrier.

Mokou: Purple man! It's about time to find out your new powers!

PK: Purple man? *sigh* Let's do this! *summons Pandora* Huh? Pandora! You're purple!

Pandora: Hmm? It seems like I am purple. It's probably due to the form you've just acquired.

PK: I guess so. Well nonetheless, Pandora! Activate Blade set!

Pandora: Blade set activated.

PK: Take my Beam Slash! *does a beam slash*

Mecha: DO YOU THINK THAT ATTACK DAN HURT US-

The slash suddenly appeared in front of them, blocking the beams.

Mecha: HOW DID THIS HAPPEN??!

PK: The most logical reason has to be dimension warping, which means... I HAVE DIMENSION POWERS!!! 

Mokou: Dimension Powers?

PK: Yeah! *uses another beam slash to strengthen the attack*

Mecha: IMPOSSIBLE- *destroyed*

PK: Hmmm... Since I have dimensional abilities, that means... I can exit out of the barrier to the outside world!

Mokou: I don't think that's a good idea. It's dangerous if you don't know the outside.

PK: Don't worry! I've lived in the outside world before I arrived here, so it's gonna be fine! Pandora! Let's go!

Pandora: Certainly.

PK phases through the Barrier with his Dimension warping. Ordinary people would be vaporized if they did that.

Mokou: I wish you the best of luck of finding this cause.

PK: Thanks for the motivation! I'll do my best!

PK leaves Gensokyo as he tries to find the culprit of this mess.

ViVIT? Where have I heard that name before?

I will provide detail about the whole dimension thing someday. I have it already planned out XD
