Thank you very much for the consideration! Otherwise, I'm afraid we'll be stuck with my artistic abilities, which are very...not good XD;

HeiShin Reverse Big Bang Event 2027 Interest Check

Hello to the most wonderful HeiShin Nation! :D 

Our next event is going to be a HeiShin Reverse Big Bang!

If you’ve never heard of a Reverse Big Bang before, it’s a fan-event where artists sign up and create a piece of art. Then writers are paired with these artists who will write a fic based on that artwork: https://fanlore.org/wiki/Reverse_Bang

Here’s an example from the star wars CodyWan Reverse Big Bang (Please note this is just an example, not how we are going to run the event): https://www.tumblr.com/codywanreversebang/672461844400766976/faq

We will be requesting artists (traditional and/or digital art) make one art-piece and one banner, and writers will write a fanfic of at least >5k words. 

Here’s our tentative schedule: 

Artist sign-ups in September 2026

Writer sign-ups in November 2026

Pairings are announced by end of November 2026

Groups finish their works by early February 2027

Would you be interested in participating? If so, please fill out the interest check below!

Heishin from this au where they don't meet till later and by the time they do cone is physically too sickly to chase criminals and do the more physical aspects of sleuthing even though he really wants to 💔

Luckily he has one very passionate fan/rival whose lifes goal has been to collab with him hehehe they're both 20 here but shinichi is physically 10

Also since cone has gotten over the embarrassment over being carried by the time they're both adults he doesn't think twice to hop onto Heiji when there's something physically strenuous that needs doing much to the shock of students (meanwhile Heiji's regular workout involves running while carrying the equivalent of Shinichi's bodyweight he is literally the buffest teacher in school )

House of Cards AU

post Holmes Freak Case

Later...

Decided that Heiji independently got tangled with the BO around the same time that Shinichi did, so by the time they meet Heiji already knows about the BO and is an agent in it and his first mission was investigating Kudo Shinichi.

I mentioned it in another post but I'm giving AU!Heiji the little stud earring to differentiate him from canon!Heiji

Welp, now that he's 'confirmed' Shinichi's death if the BO find out that Shinichi is alive, well, Heiji's cooked too. Crazy thing to do for a guy you've met twice but, hey, Heiji's that kind of guy. <3 Love him for that.

y-you don't understand shinichi and heiji are actually soulmates who are destined to be together because both have similar minds to the point of having the same deductions (and they didn't even meet yet), both are canonically equals by intellect both are the only ones who can keep up with each other

shinichi's not even in his true self and is hiding behind conan and there's wat of him coming back and yet heiji actually makes him appear by their first meeting alone

shinichi of all people who barely open up to people, actually open up to heiji about his problems, and agasa (who knew shinichi as a child) calls heiji because he's his trusted friend (which is someone who doesn't have any deep connection to anyone)

and they have this weird sensing each other in danger thing going on and both having the same gunshot at their lower abdomen

Inflicting adult heishin on the police force (why is Heiji a police detective in Tokyo? Idk why is canon Heiji in Tokyo 6 months of the year? Only Gosho knows)

I’m not joking this interaction could be canon

This scene was so intense in the anime...

My @heishinvalentineexchange2025 gift for the immensely kind and patient @caliowl333, who graciously allowed me to participate with a video instead of fic or art! (And wrote me a 20,000+-word piece in exchange?! Oh my goodness!)

Song is the SadBois & NIO Remix of "Other Side" by ILLENIUM, featuring Vera Blue, which you can listen to in full here. Ramblings under the cut!

When I first began seriously video editing, I didn't think much about composition or how well clips flowed together—lyric sync was arguably my main goal, and anime pieces were thrown onto the timeline pretty much purely based on that.

Now, I put much more care into the very visual elements—the effects, the match cuts, the dazzle. But in the process, I fear that I'm losing what audiences found engaging about my early videos: the actual ideas.

So, for this AMV, I aimed to put the most effort into a strong concept. The titular "other side" is a world without the Black Organization, where Shinichi can freely be himself. Heiji is waiting for that world, where he no longer has to lie and pat Conan's head and pretend that they're not peers, and Shinichi is dreaming of that world because he's always dreamed of working with somebody just like him. The thought of meeting Heiji someday, when he first learns of his existence (Episode 490), fills Shinichi with excitement. He does a lot on his own, but he also loves working on a team—and doing so, being with people, sharing his enthusiasm with others—is what he wants more than anything.

(Heck, there's even a piece of official art called "Conan's Dream Vacation" where he dreams of playing beach volleyball with Heiji and Ran and Kazuha—as himself.)

Sure, you could argue that Shinichi simply enjoys working with Heiji as Conan because Heiji treats him as he truly is. But the times he spends as Shinichi with Heiji point to the fact that no, he just really likes deducting with Heiji. Eagerness, big smiles—in "The Scarlet School Trip" (Episodes 927-928), involving Heiji in the case of the day takes precedence over solving it himself, as he immediately shares what he knows and even jostles Heiji awake when he learns more, before doing anything else, because there's no way he's going to solve it alone. He doesn't want to.

But as things are, being Shinichi is pain. He takes an antidote, but it's poison. Being Conan is what's become "normal" and "comfortable," but Conan can't be what Shinichi is to Heiji. Conan isn't strong enough to catch Heiji when he's falling. Conan can't save him from bullets. Conan can't even talk to him naturally without hiding and secrets. His dreams have become nightmares.

And it can't be easy for Heiji, either. To see someone you care about suffering. To know that Shinichi is in a dangerous situation—and involving himself in it applies that same danger to himself. It'd make sense for Heiji to walk away and wash his hands of it... but Shinichi really wants him to stay. Despite everything, he wants Heiji to stay. For that someday when they can be true partners "on the other side."

I tried to say other things in here, too. Shinichi cementing himself as a precious person to Heiji by countering his insecurities with a one truth prevails and this isn't a competition and you don't have to prove yourself to me. Heiji finding Shinichi even after becoming Conan because he'll always find Shinichi, no matter what, because he's dreaming of being "on the other side," too (even if he didn't know it initially). Shinichi pushing Heiji away with coldness because maybe it's selfish to want him to stay, maybe it's cruelty to involve him, but he can't deny that he cares, that he wants Heiji with him, that he doesn't want to do this on his own.

And while I maybe still went a little ham on the effects, I do hope my ideas are the strongest of all! "No effects" versus effects comparison can be found here!

Thank you again for all your hard work organizing this event, Cali!!
