"Saitama," you spoke, "Can we end this quickly? I wanna go sleep."
"Yeah, sure," he replied. The markings appeared near your eyes again, taking on a full purple glow. When Boros got a little closer to you, you two locked eyes. A purple pulse traveled through the room, and Boros froze in midair.
"Punch it please."
"Right, right." Saitama walked over to Boros.
"Straight up preferably."
"Got it." With a quick punch to Boros' midsection, it went flying up, through the ceiling, and high into the air. Boros' body outlined with purple, and you flicked your hand down. It came crashing onto the roof of the ship. "What exactly did you do to him?"
"It's hard to explain, but he basically thinks he's fighting you and I right now. Illusion of the senses, if you will."
"I see, so you sent him into a dream reality."
"More or less." You floated up into the air. "Find a way out, I'm going to bring the ship down."
"Alright. Have fun." Saitama gave you a thumbsup. When you flew closer to the ceiling, it tore itself apart to let you through. When you broke through the top of the ship, you looked around. You could hear distant explosions from under you.
'Tatsumaki.' You held your hand out towards the ship. The entire thing was outlined in purple. Slowly, you lowered your hand, and the ship creaked before following the direction. With a chunk of your magic keeping Boros subdued, and using it to bring the ship down, the markings from your eyes slowly began to grow, creating designs down your face. Looking at the ship, you clenched your hand, and the ship crashed into the ground with an explosion of debris and dust.
'I hope no one was under that...'
"Hey!"
You turned to see Tatsumaki, her body outlined in her green. The markings on your face receded when you removed your control from the ship."What?" You asked.
"What do you think you're doing? I could've handled that myself!"
"If you really wanted to, you would've done it," you replied. "Firing back artillery shells at a giant reinforced ship won't do much unless you hit the core, which you didn't."
"What did you say?! Don't talk like you know better than me!" Tatsumaki then lost her glow, green replaced with bright purple. "Hu-huh...?" Your brows furrowed, eyes glowering at her.
"I've had enough of your loud mouth. You seem to be overcompensating for your stature," you growled out, clearly at your wits end with her. "Be grateful that I don't crush you into an atom." When you withdrew your control over her, she plummeted straight down before she regained control. She just stared up at you with wide eyes. You flew off to the side, to see if any of the heroes were still there. On the ground below, in the middle of the rubble, were some of the remaining Class S heroes, along with someone else.
"Amai Mask," you greeted, gently landing on the ground. He turned his head to look at you. His expression turned to one of slight confusion.
"Y/n," he greeted back.
"Sensei, were you the one who brought the ship down?" Genos asked. When you turned to look at him, your eyes were still glowing purple, along with the markings.
"What is that?" Metal Bat asked.
"Yeah, I brought the ship down. There were a lot of things on it, but for some reason, they didn't attack," you replied.
"DON'T GO IGNORING ME!" Metal Bat exclaimed.
"Metal Bat is right," Atomic said, "If the battle is done, why are your powers still activated?"
"Oh yeah," you remembered, "I'll be right back." You jumped into the air, going up to the top of the ship. When you landed on the metal, you walked up to Boros' limp, but living body.
'I think it's about time to pull him out of his daydream.' You deactivated your powers, and Boros slowly blinked back into true reality. (Aliens prolly dont have the same gender codes(?) that we do but im gonna call it he to make it easier for myself).
"What... what happened...?" He looked over at you, whom in his hallucination, was battered, and bloodied. Now, when he looked at you, you were in perfect condition.
"I manipulated your brain to think you were fighting Saitama and I in a great battle. When, in reality, you've been lying upon this ship, unconscious, for a while."
"Wh-what--?"
"And since I saw what you did, I know how strong you are, and how much of a threat you are." Eyes swirling purple, Boros' body was outlined in purple. "I'll give you the honor I wanted to bestow upon Tatsumaki." Inch by inch, Boros' body was crushed into infinity, but he couldn't scream. The pressure you were exuding into holding him down was too great for him to move--or even breathe. If he did breathe in the first place.
"Dominator of the Universe. Falling to an earth-dweller." You watched his body become crushed with enough for to create a black hole. Slowly, half his body was gone, and soon enough, all of it would be.
"I..." He strained out with great effort. "Never... had... a... chance...!" You looked down at him with a cruel smile.
"As if you would." You snapped your fingers, and Boros' torso-and-up was also crushed, leaving nothing behind. Not even blood. When your powers calmed down, you turned, and ran off the side. The side that just so happened to have Saitama and Genos. Both of which noticed you.
"Oh, Y/n," Saitama greeted at you came down to their level. "Did you take care of Boros?"
"Yeah, he won't bother us anymore," you replied, brushing your hands together. "Let's go home."
"Did you defeat their leader?" Genos asked as the three of you began to walk together.
"Yeah," you replied. "Turns out when you're too caught up in your own fantasy, you get trapped."
"I see! I expect nothing less of you, Sensei."
"I've told you, there's nothing weaker than the mind. Especially one that's fixated on something."
"Hold it right there!"
The three of you stopped and turned around, seeing Tatsumaki."Oh wow, I didn't even notice her."
"She's so tiny I don't blame you," Saitama replied.
"I don't know how you did it, but you went in the ship on your own?! You're just a Class B. How dare you butt in like that?! I didn't need you. I could have handled it on my own! Baldy! Octopus! Boiled egg! Light bulb! Avocado! Lame face! Goblin! Bug! Baldy!"
"Y-Y/n." Saitama nudged you. "Say something."
"Ping pong ball! Rice grain! Beanhead! Kettle! Baldy! Kneecap!"
"Sure," you replied. "Shut up." Tatsumaki's rambling cut short, her body reeling back from shock.
"See? Isn't that better?" You rheterically asked before turning around and walking away. Saitama and Genos followed close behind you.
"That's Y/n for you," Saitama said.
"Amazing, Sensei!"
When Tatsumaki could talk again, she didn't. Instead, she just stared after you, a cold chill running up her spine.ONTO SEASON 2!
Ja ne!
