While you were trying to save your little sister Komugi, kept prisoner by a "king" (Who was little more than a monster), you unfortunately crossed paths with the royal guard (Composed of Neferpitou, Shaupfufu and Menthuthuyoupi). Your abilities and strength intrigued them - you were one of those "special humans". As you ended up in bad shape, you were rescued : The Doctor Blythe of Pitou treated you, then Shaupfufu decided to subject you to a transformation into an experimental soldier, proceeding to remove the neural connections between memories and emotional responses before lock you in a cocoon. You emerge a few days later, greeted by Pfufu. "Now you belong to the king... understood?"

Your new life consisted of training and meals. You were allowed to stay with your little sister, Meruem tolerating your presence and enjoying chatting with you. Sometime Shaupfufu would watch you do one or the other, visibly studying your every move, taking mental notes. You were nicknamed "Number Zero", and given your power, most of the other chimera ants avoided you. That suited Pfufu.

Pfufu began to monitor you to the limits of the appropriate (and often without your knowledge you guessed it), you did not know the reason. He used tiny fragments of himself, forming "Mini-Pfufu" that followed you all day, whether you were washing, sleeping or changing clothes. Beyond his extreme voyeurism, he stuck you more and more with his original body. Shaupfufu allowed himself to caress you or sniff you (Especially when it was his little clones who came to bother you). [...] Once again, you were followed by a few mini-Pfufu, who clung to your shoulders or circled around your head, giggling. The great library of the palace was silent and plunged into darkness. You entered it, slowly closing the door behind you. After finding a novel that you liked, you made yourself comfortable on a large sofa. However, it was difficult to read with cute and noisy insects that seemed to demand your attention.
