So far in Spy X Family, the Forger family consists of dad Loid (real identity: master spy Twilight), mom Yor (real identity master assassin Thorn Princess), and daughter Anya (a telepath). None of them knows the others’ secrets, except for Anya, except that she’s about 6 and thus misunderstands a lot of what she catches her adoptive parents thinking. Loid and Yor marry sort of out of convenience; he needs a family for a mission (she doesn’t know that) and she needs a family to placate family and social pressures (he does know at least some of this). Anya was adopted before Loid officially meets Yor, and she (Anya) may have been subjected to some sorts of experiments by some unknown entity before being adopted that resulted in her abilities. Loid’s main mission is to investigate a reclusive and potentially dangerous political figure, and the plan is to do this by getting to know him via his son (who is Anya’s age and why Anya has to go to a certain school, but this is a previous adventure).
This volume (#4) basically follows the family adventures and mishaps in trying to keep their various secrets while together working on getting Anya a dog. This gets each family member involved in a potential terrorist plot, and the dog Anya wants helps her out. The twist is that said dog seems to have some sort of premonition ability thanks to having been subjected to some sort of experiments, and is in fact perfect for Anya who can read minds, sort of. Doggy ends up with a home and the name of Bond. Yes, that’s an intentional reference.
While this whole adventure is kind of a side story, and no doubt we’ll be back to the main mission next time, the whole story is highly entertaining and a lot more light hearted than you might think given everyone’s backgrounds and the general setting of some vaguely European pre or post major international war time. Obviously there’s tension surrounding when/how someone’s secret gets out, but not too much because no one else can really be too mad on account of them keeping a secret of relatively equal weight. Some of the fun comes from the lengths everyone goes to to keep their secret and how the others sort of question but not too much because of their own secret any ridiculous explanation offered.
