Why would they? Phailous just wants to be left alone to play with toys. The only reason he has Lupa as his "girlfriend" is so people don't think he's a pedophile.
Lupa wants Brad and nobody else but got omegacucked by a much younger (granted, basically every human is), much better-looking and most important bustier airhead with daddy issues. All that's left for the Lupa is to flail around in anguish until the seventh seal is broken and it can reign supreme as the beast with seven tails.
