AN: Future Trunks won't show up until the beginning of the next chapter, I want to show how Trunks gets a crush on Marinette for the jealousy to set in. I can see kid Trunks not liking Cat Noir since he flirts with Marinette when she is Ladybug. I can see him figure it out pretty quickly, anyway I don't own anything. Please enjoy.

Trunks was staring at Marinette's bag and was confused with its content. The bell rang signaling a break Trunks quickly shut the bag. Nino and Adrien tuned around, "So little dude, what's up with the gi?"

Trunks looked at Nino, "It's comfy and easy to fight in."

"Fight?"

"Yes, fight." Trunks said, "Marinette may I play on your phone?"

"Sure I have a few games on there." She smiled and gave it to him.

"Thanks." He said, 'I'll ask her later about her bag.'

He started to play a game until another bell rang, "Come on Trunks, we have gym." She grabbed his hand and he blushed. She lead him to the lockers, "Stay here, I have to go change, Adrien would you keep an eye on him?" Adrien nodded.

Trunks watched her walk away, "What do you guys do in this gym thing?" Trunks questioned.

"We do physical activity. Have you never had gym before?"

"I am homeschooled, my father and I train though, so I guess that counts as gym."

Marinette came out, and she lead Trunks to the gym. "May I join in this class?" He asked Marinette.

"I don't see why you can't," Marinette told him with a smile.

'She's really kind and pretty. I think I like her.'

Their teacher blew her whistle, "I want everyone to start by running a mile!" She barked. The students started to run, they were shocked to see Trunks outrun them. He was moving so fast that he seemed like a blur. He finished the mile in under a minute, "Impressive, kid." The teacher said.

"That was nothing, my father has me do more than that to start out." Trunks muttered as the other students finished. They were out of breath from running.

"Okay next up is some weight-lifting. Kid, you might want to sit this one out, I don't have weights that would be good for someone your age." Trunks glared at the woman.

"I am stronger than you know." Trunks walked over to the heaviest set of weights and added about 500 more pounds to it making weigh a total of 1,000 pounds. He stood behind it and lifted it over his head and held it there. "See?" He had cockiness to his voice.

After gym was a free period, "Marinette? Can I ask you a question in private?" Trunks asked.

She nodded and they went to the library, "What did you want to ask me?"

"Before I came here I read up on Paris and about Ladybug and Chat Noir, today in class I was getting bored so I opened up your little purse to try and find your phone so I could play a game. Instead, I found a strange looking creature in your bag. Are you Ladybug?"

Marinette gasped, "How did you figure it out?"

"Simple, I saw it had the markings that Ladybug has, and looking at a picture of Ladybug and you side-by-side you look identical and your voices are the same. Honestly, I don't know how more people don't know."

Marinette was shocked. "You can't tell anyone okay Trunks?"

"I promise."

They went to meet up with the others, "So what did this little guy want?"

"Oh just wanted to know more about Ladybug and Chat Noir," Marinette said as she smiled at Trunks. Trunks smiled back at her, they heard a scream. "An akuma!"

Everyone ran off, Trunks saw Tikki, "I want to help, Marinette I can help."

"Trunks, I know you are strong but you've never faced an akuma, stay here and be safe." She transformed and swung away. Trunks looked around and flew into the air and followed her. He watched the fight, Ladybug and Chat Noir jumped onto the roof of a nearby building.

"Are you doing anything after this, M'Lady?"

"Chat, seriously? You need to focus." She said annoyed.

'Why is he flirting with her?' Trunks thought as he took a closer look at the villain, then he could feel the power level of the villain and it was low. He watched as the villain threw Ladybug into the air, while Chat Noir was fighting him. Ladybug lost her Yo-yo and couldn't save herself. Trunks went Super and caught her.

"Check it out Ladybloggers, some mysterious new person just saved Ladybug! It looks like he is only a kid." Alya said as she was recording what happened.

Ladybug saw Trunks' face smiling at her, he put her down, "Are you okay?" He asked as Chat Noir jumped over.

"Alright there, Bug-a-boo?"

"Chat stop calling me 'bug-a-boo' and let's get the akuma." Ladybug gave Trunks a look. Trunks went into the crowd and disappeared from view. The duo went their ways when their Miraculous started to beep. All of the friends met up at the park, Trunks was sitting on a bench with Marinette. The other sat down on the ground, "It was so odd, this kid with spiky blonde hair just caught Ladybug and disappeared." Alya explained.

They saw a shadow appear on the ground, they all looked up and saw a tall, sixteen-year-old boy with blue hair and blue eyes. He was wearing a black tank top under a blue denim jacket and blue jeans with a black belt with a yellow buckle. On the jacket was a white logo for Capsule Corp, and he had a sword on his back.

"What are you doing back?" Trunks asked.

AN: Mirai Trunks arrived, why could he be back and what will everyone think of him? Stay tuned.
