“Good one.” The blond detective commented to the preening thief. “And yes.”

Kuroba’s face lit up as he grinned broadly back.

“Took you long enough, Hakuba.” Kudo grumbled from where he was draped across the sofa. “Think you took the longest to solve the riddles out of all of us.”

“He did. Twice as long as your time.” Heiji confirmed with a smirk. Other than one moment early on where the Brit had paused and looked up at Kuroba with a questioning glance and was met with a nod, Hakuba seemed to struggle with it. Which just went to show who the superior detective was.

“Actually.” Kuroba said, standing up with a stretch. “He solved it the fastest. Under half of either of your times.”

Heiji shared a confused look with Kudo. “What?”

“They missed the second code?” Hakuba inquired, also rising and tucking the chair back in under the table.

“Yup.” Kuroba grinned, piranha-like, all teeth. “They got the first one, calling them idiots, and stopped there.”

Heiji stared at Kudo. A second code.

“In that case, I believe victory is mine.” Hakuba drawled, turning to the theif. “Shall we adjourn to the address on the second code? My treat, as thanks for such a delicious brain teaser.”

“I’d be delighted.” Kuroba agreed, actually looking so. They left, Hakuba asking a quiet question about the process of developing the codes as the door closed behind them, and getting a proud grin in return.

Heiji did not quite whine as he realised that he’d just missed a chance to pick Kuroba’s brain on how Kaitou Kid’s twisted mind worked.

“You still have your riddle, right?” Kudo demanded, rising from his seat, pulling a folded paper out of his wallet.

An original Kaitou Kid riddle, personalised for him? Of course Heiji still had it. He pulled it out, setting it on the table as Kudo sat down across from him, frantically rereading his own riddle.

A freaking second riddle.

More fashionably late heishin week stuff for the prompt "not!detective AU"

They're both in their 40s but shinichi is physically in his 30s, both are retired high school detectives-turned teachers but they retired for different reasons.

For Shinichi, the Conan thing happened but it was way more traumatic and less shenanigany. Also much shorter, with the help of the 294839291 undercover agents he takes down the BO in like 3 months but at the cost of crippling trauma and also permanently stunted growth & generally sickly body from taking the temporary antidote too many times.

He is still capable of solving a murder and chasing after the killer, but the physical and mental aftermath takes its toll and so (after Ran/Agasa/Shiho etc staged an intervention) he had to reluctantly retire from being a detective. So he's now the mildly depressed sleeo-deprived literature teacher who creepily knows everything about everyone due to his deductive capabilities. And yes his sense of fashion is nonexistent he's wearing the same uniform since 7. Everyone is a little scared of him but he's a beloved teacher and clearly loves his subject (do NOT get him started on whether Holmes counts as classic literature though)

Meanwhile Heiji is the mildly eccentric but very popular science teacher who knows a a suspicious amount about dead bodies but he's super friendly!! And great at Kendo!! So everyone loves him!!

(Back when he went on his little field trip to look for the Missing Kudo Shinichi, the BO was alrd taken down and Shinichi was in witness protection and therapy and also physio with like 10 secret organisations protecting him so they couldn't become besties then. The reason Heiji retired is very long winded but starts with that lmao)

Anw yes from the students POV Hattori Sensei loves following Edogawa Sensei around like a lovesick puppy (and their desks are next to each other at the teachers lounge so you know their love is trueee they are work husbands frfr). Hattori the type of teacher who doesn't stop talking about his favourite person so half the reason everyone loves the cold and distant Shinichi is bc of the random cute facts about him Heiji drops in the middle of class

I feel like it's kind of a detective adjacent AU BC they do end up solving all the little mysteries happening around the school and maybe there's a Mystery Club and the pov is all the students observing the romcom that is heishin.

Best part is definitely when people are like "how do those two get along so well??" And then something happens and they show that they are the EXACT SAME BRAND OF FREAK

Also picture the Mystery Club students deciding the mystery of the week is heishin and then researching them and finding multiple headlines where both of them were teenage detectives who regularly solved unsolvable murders like HAHAHAHA even better if the teacher in charge of their club is some rando and not Heiji or shinichi

Also! When shinichi first becomes a teacher and he's like physically 22 so 32 year old Hattori is totally cradlerobbing him from the other faculty's POV HAHAAHA
