Rikuyo
Playing games? She was completely serious now, this was some games... Oh shit, he was trying to escape! If he managed to retreat before she could get to him, this would be really unsatisfying. Damnit, the first time she used this form she didn't get to defeat her opponent, so she wasn't happy with a tie like that. Her frustration lead her to possibly shortening the time she could maintain her form, firing a blast from her hand to overpower the stakes. Trying to evade or brute force through them physically would just buy him more time, so Rikuyo gambled on that energy blast to reach him. If that didn't work, then well, shit, she'd have to work out something later, after she regained her strength. That is, if her opponent actually retreated and didn't come back to finish her off.
