Also posted on tumblr and Ao3.

This first prompt I used to set up my headcanon for this ship, which will be greatly expanded upon in a longer fic I hope to write in the future. A lot of the material you see here will probably be reused later, either in whole or part.

I do not own ZEXAL or this would be canon and not headcanon.

Also, I have not yet seen the end of ZEXAL (I watch the dub) so this is based off spoilers and my own speculation.

Please enjoy!


Vector isn't quite sure when it happens. Somewhere between pretending to be 'Rei Shingetsu' and the massive amounts of time he spends with the human, he realizes he has a crush on Yuma Tsukumo. But then he "reveals himself" to be part of the Barian police force and he's able to act a little more like himself. Just a little, and only when he and Yuma are alone.

But as he's talking down to his "subordinate," Vector can pretend that he doesn't maybe like Yuma more than he should.


It's when Vector hears the desperate scream of "Shingetsu!" and suddenly there's a hand holding his, the grip firm but slipping with each second, and he's staring into ruby eyes brimming with tears, that he knows he's in love with Yuma. And he knows that Yuma still thinks of him as 'Shingetsu' because Vector is his enemy and Shingetsu is his friend, and maybe, just maybe, they could have had a relationship not based on lies; but none of that matters anymore because it can't happen now.

Yuma's grip is slipping.

Rei Shingetsu smiles. "Good-bye...Yuma-kun."


Vector doesn't know why he's here, why he was saved, why Nash is only yelling and not trying to kill him, why he isn't dead because oh god he deserves to be dead, the things he did-

He barely even registers the words being said, doesn't quite realize that he's curled in on himself bawling - though he does know his eyes are hot and wet and he hurts - barely feels it as Yuma pulls him into his arms. But through the spinning thoughts, one softly whispered word does reach him.

"Shingetsu…"


It's been a month and Nash, Ryoga, is starting to get pissed at his new 'roommate,' and Vector - Shingetsu, whoever the fuck he's supposed to be, he doesn't even know anymore - finds himself standing on Yuma's doorstep, repeatedly telling himself this is a bad idea but I'm still 'Shingetsu' to him, right, that's what he called me last time, of course I'm not still Shingetsu, I'm an evil asshole and a little shit-

And Yuma opens the door.

Shit. When did Vector ring the doorbell?

The boy looks startled for a moment and Vector considers just running away as fast as he can, but then there's that little smile and "Shingetsu."

Okay, Vector's knees did not just go all weak and wobbly on him, nope, not at all - oh who is he kidding, his knees have been wobbly ever since he got here. He swallows thickly. "I…" He still wants to run but he's pretty sure if he actually did, he'd get about one step before his legs really did collapse under him. "I'm sorry. Can you forgive me?" he almost chokes on the words, because there! I said it! Are you happy now, Nash? because he's going to say no and I'm going to return to camping on your couch feeling sorry for myself and-

And Yuma is giving him this quizzical look like 'forgive you for what?' and it just makes Vector want to scream in frustration-

"Of course."

"What?" Vector croaks.

"Of course I can forgive you," Yuma smiles. "But," he frowns a bit, "I think you need to forgive yourself."

And that's all it takes. Vector's bottom lip quivers, and then tears are falling from his eyes, and Yuma hugs him, and then he's outright bawling against the human's shoulder. And through the sobs and mangled apologizes, he's pretty sure that damned "I love you" slips from his lips.

If Yuma hears it, he chooses not to respond. He only hugs Vector tighter.
