Akane smile knowing how sensitive some Demons were in those areas. Of course she mostly used them for more lethal purposes than now. While it was a cute reaction she didn't like babysitting without any action to help out. The others caught up and were able to help protect the Princess from herself mostly. "On closer inspection your highness these things aren't wondrous at all. Honestly I find your interest in them surprising." To her this was a place full of annoying creatures that were either uninteresting or a nuisance. Some were outliers like Yuki or Kaede, but she doubted they would find many who could wield a large weapon with only one arm like a Demon.
They stopped when the revenge seeking men showed up brandishing weapons. Akane quickly assumed a position in front of the Princess hoping to keep her from intervening. It wasn't their fight yet. Akane did find it extremely entertaining for someone like her. While mere humans she did want to see at least a little bit of Asuka's skills. It however disappointed her in the end how they ran. Asuka was indeed a skilled and seemingly cold warrior, but they didn't even try to finish the job. "Well done Kushiami san, but it seems like they lacked the fortitude to finish what they started. Now that's unfortunate." she sighed almost sad to see it was over so quickly. Of course it was easy to get over since they were merely human rabble, so nothing impressive.
It seemed like the action was over for the moment. Before they moved through the crowd a series of blades shot out and hit the Princess. Akane reacted quickly covering the right side of the Princess and raised her Naginata ready to battle. The direction of the blades were apparent and with the Demon Slayer's reflexes she could prevent the princess from being harmed anymore. "This makes me wonder what that poet would do if she saw this." she mused while looking all around at anyone who noticed her other features. "Please i beg of any of you to act. Anyone makes one move against her will be eliminated swiftly. Its the only mercy I can give beasts of burden." The light shined off her Naginata's blade as if to emphasize what would deal with them if they didn't heed her warning.
