Hajime
At first Hajime had thought that his question would be lost in this mess of activity. He himself was distracted by all the new hijinks, with Kei carrying Shuu out of the room, and Atasuke and Anami getting down to the cleaning. The shrieking of both Kei and Koneko accompanied everything. He was about to get up to help with the cleanup, after all, who better than him? But then, Shuu returned and answered his question from earlier. Hajime had to admit, he was mildly reliable. Very mildly. But he was more concerned with the announcement that they would be participating in a tournament.
"Now you're talking my language!" He exclaimed. Hajime had been competing in martial arts tournaments since he was a kid, and he won every single one of them. Of course, this 'tournament' was being hosted by a fruity sounding company that probably didn't intend for them to get through by punching everything. But that was okay; Hajime was brilliant enough that he would get through or punch enough things to succeed anyway.
"Do we get to pick our partner?" He asked. Hajime felt he didn't need a partner, but he could think of plenty of people that would be a pain to be saddled with. Isabella was first on that list, as even if she could probably handle herself she would be nothing but a nagging wind in his ear. If they were going to get chosen randomly, then it would be the devil's luck that he would have to endure her nonsense the whole time. All he really needed was a partner that would shut up and let him lead the way to victory, however.
