(Long battle. It's interesting though. Also, I noticed Yuuka doesn't have a lot of canon spell cards. So the spell cards that she use in RP are made up to fit her power.)
Adachi District Warehouse - Tokyo - Japan
Time: 6:30 PMDue to the focus the agents were putting on the left side, Yuuka was able to breach the warehouse without any action. She immediately rushed to the other end of the warehouse, but was stopped by a blue-skinned man with swirling tattoos around him. On his back was a scroll that embodied powerful magic.

"You shall not pass, lady." The man announced as his right hand gathered dense arcane magic and threw it at Yuuka.
This is definitely something I can't block with my parasol, Yuuka thought, as she strafe'd to the left, dodging the energy ball. The energy ball hit one of the metal crates and exploded.
"Let's go, let's go!" The man summoned orbs of deceptive magic, and hurled them at Yuuka. Yuuka fired flower danmakus to block them with ease.
"Come on," Yuuka smirked. "You have to do better than that."
"I'll show you arcane magic!" The man's eyes glowed as he summoned more arcane spheres. Yuuka drew one of her spell card.
"Spell Flux!" The blue man yelled. The arcane spheres split into six-fold and were headed straight to Yuuka.
"Bloom Sign - Seductive Daphne." Yuuka muttered. From behind her, Daphne-shaped bullets streamed out, colliding with the spheres.
"Overload!" The blue man bellowed, and one of the sphere gained density and power, absorbing all Daphne bullets. It headed straight to Yuuka.
"Blossom Sign - Angela's Trumpet." Yuuka used another spell card. From the card, trumpet-like bullets showered, confronting the dense sphere. The sphere absorbed some of the bullets, but was eventually stopped.
"You are an irritating woman." The man gnarled. "Can you handle this?"
The blue-skinned man's eyes glowed with blue energy as he raised his hands in the air and gathered stronger arcane power. Then, he did something unlikely. He ate the energy, and muttered, "Desperate Power." Then, the man lunged into Yuuka. All bullets that collided with him were turned into nothing as the man swiped at Yuuka. Yuuka backed away, and the man relentlessly swiped at Yuuka. Yuuka used her parasol to parry the man's assault, ducked under him, and fired bright bullets that left the man blind. The overwhelming energy around the man faded as the man gasped for breath.
"Before I finish you," Yuuka said as she pointed her parasol tip at the blue man's head. "Tell me why you joined these hooligans."

"They promised me." The man panted as he turned to face Yuuka's bloodthirsty face. "This arcane technique I hold... it must not be spread amongst the humans of this world. The organization, Neo-Yakuza, claimed that they can keep this technique secret, so that no other human will suffer."
"You should've had a better common sense to believe that they were lying." Yuuka said as she charged a laser from the tip of the parasol. The blue-skinned man closed his eyes, ready for his death.
If I kill this man, Yuuka thought to herself as the laser was charging.
What will I gain from it? It will only lead to a Character murdering another Character for no reason.Yuuka aborted the laser, and said to the surprised blue-skinined man. "Go, and live a better life than being bossed around by scum excuse of humans."
