Summary
The rabbit seemed to snap back into focus, eyes back onto Leo’s. “Sorry, I'm bad with long speeches. Could you summarize for me?”
Leo squeezed his snout between his fingers, exasperated. “I need to see you again in a couple days.”
“Like a date?”
“Yes, like a–” Leo looked up frantically, blush spreading across his cheeks. “No, not like that! I'm worried about the severity of your injury!” He looked away again. “Look, is there somewhere we can meet so I can make sure you won't die from this?!”
“Wait what's your name?”
AKA Leo goes undercover as a battle nexus medic to try to uncover one of Big Mama's plots, but ends up treating a cute rabbit yokai instead

Summary
"It's crying, what a baby! Gonna go cry to your kappa mommy, freak!?"
He was kicked again, hard in the shin, and the whole group laughed heartily, echoing in his tympana over and over again. He was going to die. His lungs desperately heaved in his frozen chest and he tried again to cry out, but all he could manage was a whimper. Shame rotted in his gut as stood there, useless.
"Hey!" A new voice yelled. "Cut it out!"
A human girl broke free from the bushes and stormed into the clearing, waving a baseball bat menacingly.
Oh no. It was her.
AKA An au where the rise bros actually ARE kappa yokai and they do not like humans very much. Don't worry, I think April might just be able to change their minds.

Summary
"Apologies." Donnie said, stiffly, and willingly rolled his sleeve up for Leo to see. "It appears that working on the engine reopened the injury on my arm."
"What 'injury'?" Leo echoed stepping forward again and furrowing his brow as he inspected the arm Donnie held out. Careful partial roll of the sleeve. "Why the hell didn't you tell me? And why isn't it bandaged?"
"It was a minor burn." Donnie said, and it felt like his throat was scorched and burned with how hard it was to speak. "I ran it under cold water. It wasn't a big deal."
