The world Loid and Anya live in is extremely paranoid and treacherous, with people fucking each other over as easily as breathing. Kind, innocent souls like Yor risk getting reported simply for being single, since its believed such spinsterism threatens the nation’s birth rate. So when one of her bitchy co-workers invites her to a party, she’d better have a man on her arm.
It speaks to how dark and unpleasant this world is that even otherwise decent people like Loid and Yor are spies and assasins, respectively. Yor in particular really sells the “Thorn Princess” persona with an absolutely killer costume. Indeed, Yor’s penchant for wearing elegant headbands, along with Hayami Saori’s soft, warm voice, instantly endear me to her.
Obviously, these two kids simply have to meet; their interests and departure from the norms of shitty society align too perfectly. It’s just a matter of when, and sure enough, it’s at a clothier. Loid needs to buy fancier clothes for Anya, while Yor needs her only nice dress, torn during her killings, repaired for the party.
Loid is struck by how easily Yor sneaks up on him and how she can feel his gaze, while Anya uses her mind-reading to clear Yor’s misunderstanding about Loid being married, thus facilitating an arrangement between the two. Loid will attend the party as Yor’s boyfriend, while Yor will attend the meeting at Eden as Anya’s mom.
Unfortunately, the party is on Saturday night, the same night Loid is ordered to steal art from some smugglers. He tries to fit both obligations in, which is a recipe for disaster, and while he’s able to take out 38 thugs without too much trouble, a 39th and 40th ram him with their car. Meanwhile, Yor has to endure the party all alone, exposing her to her co-worker’s scorn and mockery.
When Loid shows up at the last minute and accidentally introduces himself as Yor’s husband, he’s bloodstained from a “violent episode” from a patient, saying he’s a psychiatrist. Camilla is so pissed that Yor has such a hot partner that she tries to toss piping hot gratin on Yor, only for Yor’s catlike reflexes to kick in and not only avoid getting burned, but saves the food.
When Camilla brings up rumors about Yor going to the hotel rooms of gentlemen for “massages”, Loid simply says it’s splendid for someone to endure such trials and sacrifice for the sake of someone they love—in Yor’s case, her little brother Yuri. He may not know she’s an assassin, but she knows she’s better people than trash like Camilla and her ilk.
After taking their leave from those preening assholes, Loid ends up getting Yor tangled up in the leftovers of his art-stealing mission, as the smugglers try to kill them both. When Loid is nearly stabbed by one thug leaping down from a fire escape, Yor saves his damn life and impresses the hell out of him by kicking the baddie into the next zip code.
Reveling not only in how well they “work” together but that this Loid fellow clearly understands what it means to not be “normal” (i.e., what everyone else is and expects them to be), she ends up asking for the very thing Loid needs: marriage to a woman to seal Anya’s admission.
It truly is a mutually beneficial partnership, and it’s commemorated in the most spy/assassin-y way imaginable: the diamond ring Loid nicked fell through a hole in his pocket, so he uses the ring of a grenade on her finger instead. And just like that, we’ve got ourselves a Spy Family.
