Let it ring 'round the world: Part X is up.
"There is one thing I should alert you to," Crow stated. "Armor Master doesn't take any damage nor can it be destroyed in battle." If Luna had gone into battle not knowing of the Blackwing synchro's immunity, Stardust would be destroyed.
"That's where this card comes in," the girl responded, holding up a card. "With Synchro Mirror, I can switch the special abilities of any synchro monster on my field with one on your field. In other words, Stardust Dragon becomes invincible for this turn." When it was activated, the dragon and armored bird glowed in correspondence to their color schemes and swapped them.
"Go Stardust, attack!" she tried to declare. The dragon's wings spread out and it launched itself at Crow's Armor Master, destroying it on contact.
"That's not good," Crow squeaked while he looked at his monster once stood. One of his best monsters was gone in one fell swoop.
"I'll place one card face-down to end my turn," the girl concluded.
"I'll draw then," the Blackwing duelist said to hold four cards. "Let's have Blackwing-Blizzard the Far North join the fray." A white dove-like bird, only with a bigger beak, flew in, ready for duty.
"With Blizzard's special ability," Crow explained, "I can bring back any level 4 or below Blackwing in defense mode. And I choose Gale the Whirlwind." A blue vortex appeared on the ground and Gale floated up in a blue color.
"Since there's at least one Blackwing on my field," he continued while selecting another card from his hand, "I can summon Bora the Spear as well." A lance-bearing bird humanoid emerged in a veil of feathers. "Next up, Gale's ability activates, cutting Stardust Dragon's attack points in half." The eyes of the bird in defense position glowed red and launched a barrage of wind, lowering the dragon's strength.
"Go Blizzard! Blow Stardust off its feet!" Crow declared. The dove-like bird flew fast enough to become a flying spear.
"Go Synchro Deflector!" Luna exclaimed, flipping her trap card up. "Now your attack is negated and one monster on your field is destroyed. Like your Bora." Crow whipped around to see the lance-bearing bird explode in a shower of pixels.
"Guess I'll stop here," the Blackwing duelist concluded.
"My turn," the girl stated to hold a single card. "I play Tuner's Harvest. For every tuner monster on my opponent's field, I can draw one card." Luna reached and drew to hold two cards.
"I play Big Bang Shot," she said, holding up an equip card. "Not only does Stardust Dragon gain 400 points, but it gains a piercing effect as well." The dragon coursed with new power, increasing its attack points to 1,650.
"I think I'll go after your Gale the Whirlwind," Luna commanded the dragon. A ball of energy built up in its maw and fired at Gale, vaporizing it and reducing Crow's life points to 2,550.
"Next up is a quick-play spell: Second Rebound," the girl added. "If a creature on my field destroys one of yours and inflicts damage, it can attack again." Stardust launched another blast of energy, obliterating Blizzard and bringing Crow's score to 2,200.
"That's all I have for this turn," the girl said to end her move.
"You're good, kid," Crow complimented Luna as he drew to hold three cards. "But how will you stack up against Blackwing-Shura the Blue Flame?" From another veil of feathers appeared another bird humanoid with blue-colored feathers and massive wings.
"Shura takes down Stardust!" Crow hollered as his monster slashed at the dragon's neck and annihilated it. Once Luna's score became 3,750, Crow held up a single finger as if he had more to play.
"Now Shura's special ability kicks in," he explained, "which means I can summon another Blackwing from my deck with at most 1,500 attack points, like Kalut the Moon Shadow." From out of nowhere came another bird, half of Crow's height, with an extravagant display of yellow feathers atop its head.
"Kalut attacks you directly!" he exclaimed while the bird used its talons to tear at Luna and reduce her score 2,350.
"Easy, Crow," Yusei tried to warn his friend. "She's only a child."
"Don't worry Yusei," Luna cautioned her savior. "I'll be fine. After all, you've given me some of your strength." She drew to hold one card in her hand.
"I use Monster Reborn to resurrect Stardust from the graveyard," she stated as the dragon returned in a curtain of light, ready to battle. "And I'll have it attack your Moon Shadow!" The beast built up another blast in its maw and launched it, extinguishing Kalut and reducing Crow's score to 1,100.
"She's holding her own out there," Yusei thought. "Just don't let up."
Crow stayed quiet as he drew to hold three cards again. His face looked worried, an indication he might lose. With limited options available, he switched Shura into defense position and continued to stay silent.
"Cat got your tongue?" Luna asked, feeling confident as she drew another card. "In any case, I'll bring this to a close with Nitro Unit. By arming this to Shura, when it's destroyed in battle, its attack points are taken out of your life points." Crow immediately bowed his head in defeat.
"Go Stardust Dragon!" the girl declared as the beast took out the Blackwing and triggering the equip effect, bringing Crow's score to zero.
"Alright Luna, you won," Yusei congratulated the girl on her victory. She slowly dropped to her knees, slowly panting in exhaustion.
"Yeah….I did," she exhaled. "I probably should've mentioned that I tire out quickly after a duel."
"What do you mean? Do you not have the physical and mental endurance?" Crow questioned the girl as he walked closer to see what was happening.
"I kind of do have the endurance," Luna answered back, "but I mainly use it to maintain my connection to the world of the duel spirits."
Yusei and Crow looked at each other confused at what they just heard. Yusei removed the duel disk and Crow carried the girl to a nearby crate so she could regain her strength.
Now Luna has revealed her connection to duel spirits. Will Yusei and Crow believe her words? Keep watch for Part XI. Also, I know almost exactly how I should end this story. But if any of you all have suggestions for plot elements/additions, let me hear 'em.
