Some relationships are meant to last forever. Even if they're not perfect, even if they're full of obstacles, even if it's against the whole world and God himself. Appreciation blog for the HeiShin ship, and anything related to the miraculous bond those two have created. Here you'll find Screenshots, gifs, heishin moments, character and case analysis, random fangirling, fanarts and fanfictions, and last but not least, Hattori of the west and Shinichi of the east will reply to any question you'll ask! We hope you'll enjoy your stay and become part of the official HeishinSquad! ♡ ~ Mods #Finn , #Kimmy and #Lunick
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!!
really messy doodle but I genuinely liked the idea of thresher shark shinichi because of how it fits him so much (also mermaid heishin because why not and I haven't seen any much heishin content)
Aka that one time in middle school when Heiji and Shinichi met, both solved the case but since they each had gotten a clue from their dads and didn’t know the other had, decided not to take it as a victory because they thought the other one was a better detective
So then they both just left
(And the fact conan didn’t tell him that it was him, smh)
"There are better places to take a nap than on the ground ya' know!"
