Liam wanted the girls to keep a low profile and not attract too much attention, if they had stayed in their category it still might have been possible, but that was out of the question now that they had chosen both to fight in the higher category with the participants who were all at level ten, how could they remain low profil when they will surely crush everyone.
As remaining discreet was no longer relevant, Liam thought that they might as well give everything to win the competition and do their best to train them that way the girls will not get hurt, at least not too badly.
Their group was strong enough to face threats now so it was okay if the girls wanted to show off, and soon Snow, Sky and Lilac will be able to transform into human too, it would take longer for Flame and Arthur but in the near future they too will become very powerful.
