Sera's eyes widened as she watched Mitsui pull out his sword from his sheath, internally freaking out. This was the end of her. Here, while her home was burning to the ground. As he brought it up, she shut her eyes in fearful anticipation. But she never felt the oncoming blow. Peeking open one eye, she saw that the sword never even touched her. In fact, it was in front of her, like a shield. 

[i][b]"I will not raise my blade to children."[/b][/i] Mitsui announced. Sera turned to the purple-haired man who was staring defiantly at the bat-creature. He was... defending her? Even at the cost of his life? That was so-

Wait. 

Did he calle her a [i]child[/i]?

How old did he think she was?!

As much as Sera wanted to voice her concerns regarding his thoughts about her, she didn't get the chance when the familiar screeched.

"You will pay for disobeying Lady Karasuko's orders!" He screamed before diving off the building towards the two of them. Although Sera was still unsure what to think of the swordsman, with his sudden alliance change and strict moral code, but she knew she had to do something to help him. As the familiar closed in on the two of them. Sera took a step back, timing it closely in her head. The moment he came into range, Sera jumped forward and began shining a bright light. The light changed shape and spun in midair, transforming into a double-headed scythe just in time to slice the bat's wing. Sera then immediately transformed back into her human shape as the bat screeched and crashed into the cobblestone sidewalk. 

"Mitsui, now!"
