A little snippet from Nitori's perspective since most of the story is in Rin's perspective. And also some Momo action because he didn't get much screen time.
*BONUS*
Previous to the Raid
"You're doing what?" Momo yelled.
"Keep your voice down!" Nitori hissed.
"You're doing what?" Momo whispered at nearly the same volume.
"I'm going to let myself get arrested," the mobster shrugged, "That deputy is on our trail, wouldn't want to disappoint.
"Are you telling me this whole time, not disposing of the getaway car like usual, that 'anonymous tip' were all part of some scheme? Why?" Momo's eyes had grown wide, "and here I'm usually the irresponsible one!"
"You're always the irresponsible one," Nitori corrected, "minus this one time."
"Yeah well, you still haven't told me why you're blowing this whole popsicle stand," Momo stretched his hands over his head, accidentally knocking off his fedora. "And by popsicle stand, I mean-"
"I know, you mean the whole operation," Nitori frowned, "my rationale is on a need to know basis. In the meantime, while the raid is going on, you will be-"
"I got it!" Momo pointed at Nitori, "You think that redheaded cop is cute!"
Nitori colored instantly, "N-no, that's rid-diculous….I'm just…" he shook his head, "while the raid is going, you will be doing a very important errand for me, okay?"
"What! I don't get to be a part of the raid?" Momo groaned, "I was gonna have a code name! We were gonna use walkie talkies and be like "Stagbeetle to Sharkbait, what's your angle?" he started pacing back and forth, "when am I ever gonna have the chance to use that code name? It's a stroke of genius I say!"
"Focus Momo," Nitori sighed, trying to be patient, "while I await capture, you will be kidnapping this young lady," he pulled out a photo.
Momo, not listening, grumbled, "he probably doesn't want me to get in the way of his cop boyfriend - oh hey is that a girl?"
Sometimes having Momo as his second in command was more like having a puppy. Nitori repeated himself, "you'll be kidnapping Miss Gou Matsuoka. She's the deputy's little sister. I'll need her as leverage for my release, understood?"
Momo took the photo like it was a present, "so cute," he whispered. "Are you sure she's his sister?"
The mob boss rolled his eyes, "Of course, I made sure to get the deputy's name when he was interrogating me. And the girl is to be taken unharmed, gently, and unbothered by your flirting, capiche?"
"Aww, of course you have to suck all the fun out of this!" Momo whined, "first I can't do the raid, then I can't even flirt with this cute girl. You really are just as brutal as everyone thinks you are, boss."
Nitori shook his head, "do you remember when you first started being a criminal?"
"Yeah, sure, did some petty crimes, kinda liked it," his smile slanted, "dragged you into it too, didn't I?"
"Mhm, until I got sick of being arrested for your ill thought out thefts."
"You were always tentative in that respect...afraid of a little fun," Momo smacked him lightly on the shoulder.
"Sure what's more fun than being stuffed in a prison cell with twenty other smelly burly men," Nitori shook his head, "running the entire black market is so much more effective, and lucrative."
"Yeah, 'specially when no one suspects a seasoned mobster to be a fragile young man. You fooled everyone." He tucked the photo into the front part of his trench coat.
"Except Rin," Nitori murmured.
"Mmm. Be careful with this, boss. Your pretty little face doesn't belong behind bars.
"And you be respectful and courteous with Miss Matsuoka." Nitori countered.
"Fine. Oh, and if that Rin guy gives you any trouble, kick his ass for me!" Momo did a fist pump.
"Don't you have someone to be collecting?"
"Whoop yeah!" the bobbing, over enthusiastic mobster sprang into action, disappearing from the hideout.
I really like this mobster/police AU so I'll probs be posting a few more bonus one-shots
