The Beginning

Meeting the family: Leo

He wanted you to meet his family really badly, so he texted you to get a pizza then meet him in an alley.
You went to Antonio's pizzeria and got a few pizza. When you went to a dark alley a homeless guy came up to you and tried to run away with the pizzas, but Leo jumped in front of the old man and the guy fainted.

"Please tell me he's not dead?"

"He's not, don't worry, if you were him wouldn't you faint if you saw a giant turtle?"

"Probably."

He then picked you up bridle style and brought you to the sewers.
He started to explain his brothers to you.

"Mikey has the orange mask and he is the childish one. Donnie is the purple mask and he's the genius in the family, and then there's Raph, he's the red mask and most aggressive one."

"So Mikey equals orange, Donnie equals purple, and Raph equals red." you looked up at him.

"Yep, and I forgot there's also a giant rat named Hamoto yoshi, but call him master splinter. Okay?"

"Okay."
You replied back. When you guys got there you heard a loud bang
and someone yelling.
"MIKEY!"

You get close to Leo and grab his arm. He looked down at you and chuckled. You am saw Raph soaked in water from head to toe and Mikey running behind you guys.

"Mikey, what did you do this time to tick off Raph?"

"I threw a water balloon a him while he was doing push ups."

Leo sighed, then he grabbed you, and you both moved to the side.

"Raph! He's over here!"

You looked at Mikey and saw how terrified he was, then you saw Raph running towards him and you stepped in front of Mikey.
Raph stopped. Him and Leo looked at you funny. Mikey had huge eyes, starring at you. Donnie walked out talking then he stopped and looked at Leo and you.
You saw Leo get nervous, but he then looked at his brothers and said.

"Raph, Donnie, Mikey, this is
(y/n). She's my girlfriend and now we are going to see sensi, so bye."

He started to push you to a room with a beautiful tree in the middle of it.

"Wow, what room is this?"

"It's the dojo, but shhhhh he's meditating."
He whispered to you.

You saw a giant rat behind the tree. When he stopped his trance he came up to you and Leo.

"Sensi, she's kept my secret for a long time and I think we can trust her. So can I keep her?"

Sensi looked at you and told Leo,
"Yes."

Leo got so happy he gave you a tour of the whole place.
