Nagi gets Hayate to first try on a female school uniform, much to his displeasure and before he can do anything about it, Maria comes to Nagi's room and sees what is going on. Nagi and Maria then proceed to put Hayate in a full cat-girl outfit which entices Tama's animal instincts. Afterwards, Hayate runs into Klaus and initially tries to run away, but in the end Klaus' instincts take heed, and Maria must interfere. Later, Hayate and Maria play a game of pool where if Hayate loses, his debt will increase to 200 million yen. Maria is taking her upper hand and wants Hayate to marry Nagi. However, Hayate refused that offer, but he said that Nagi is a very kind girl. When Maria missed the shot, Hayate manages to hit the billiard to the hole, thus winning the pool game.
