(It's fine-)
Katsuki followed behind him, he wasn't in his suit or anything yet-BUTTTTTTTTTTTTTTT-They weren't the only ones who heard it.
Ren was on a bus that was on a high way, looking out the window, extremely bored. He had heard the explosion from there-his eyes widened as he saw a bunch of smoke far away. He tapped the girl in front of him, which was his friend, her name was Maria.
"Maria-I need you to distract everyone-"
M: "Oh-okay-um-EVERYONE!! LOOK AT THAT SMOKE OVER THERE!!"
All of a sudden, everyone turned to look out the window. They all crowded around a window, looking at it.
?: "Woah!"
??: "Oh shit-cool!!"
???: "Holy fuck-"
Ren quickly zipped open his backpack, grabbing his mask. He then grabbed his backpack, swung it over his shoulder, and opened a window that was on the other side of the bus. He looked behind him-no one was watching. He slipped on his mask, getting out the window. AND BAM-he was now on the roof of the bus. AND WOW-his suit was on.
"Okay..you got this Ren-"
He then pointed his wrist outwards, making a string-web that attached to the top of the bridge. He then started swinging himself towards the explosion.
