One day, much to their surprise, Ascoeur and Q-feuille find themselves assigned an actual mission: to babysit a special little girl named Di-air. Things go smoothly at first as the two get to know Di-air and become her friend, and they show her around GTO headquarters and take her outside to play. The problems begin when, while outside, the three are approached by the hostile duo Rubis and Saphir who are from the same group as the assassins from before. It turns out though that Rubis and Saphir are not after Di-air and had instead come to face Ascoeur and Q-feuille, and the two struggle against Rubis’ feral form and Saphir’s ice powers. Ascoeur in particular can’t make good use of her limited teleportation powers against Rubis, but the tides of battle turn after she gets a kiss from Di-air, and she’s suddenly able to use much more advanced techniques. Rubis and Saphir are eventually forced to retreat because GTO security finally shows up, and Ascoeur and Q-feuille report back to Chief Hiver. Despite the attack, Chief Hiver decides to continue to leave Di-air with them, and Q-feuille in particular wants to take care of the little girl.
