Genichirou Haneoka is the devoted husband to Eimi and father to Meimi. A dedicated first-class professional stage magician, he constantly innovates, experimenting with new tricks for his performances. He met Eimi during his own magic training and married her despite her secret past as the infamous phantom thief "Kaitou Lucifer." Genichirou harbors a strong hope that Meimi will follow his path into a magic career, reflecting his professional pride and desire for legacy. He remains completely unaware of Meimi's secret life as the phantom thief Saint Tail, a secret kept from both parents. Genichirou unwittingly cultivated Meimi's exceptional magical abilities through his influence and indirect guidance, though he doesn't realize she uses these skills extensively beyond his oversight. The name of Meimi's pet hedgehog, Ruby, traces back to Eimi's ruby engagement ring, a symbol of Genichirou and Eimi's bond. Genichirou continues his successful magic career while Eimi, having left her thieving past behind upon marriage, maintains their conventional family life as a housewife.
