Yuki
"I know I know" Yuki replied to Flint.
She continued to watch the fight with the binoculars. Wait, since it was a human .... the source .... Yuki activated her powers, and her eyes went red. Sensing the vibrations around, she could feel there was a Gastrea crawling up behind Flint and Yuki.
"Tsk..." Throwing her poison coated Javelin up, angling it just right behind herself. The angle was precise, the wind calculations were precise, as it arched over and started plummeting down, it pierced through the source Gastrea, taking it down and into the ground. It was pinned but not quite dead. The poison pulsing through it, it stopped moving, but was still alive.
"I'm going to take care of what I believe is the source. It just tried to sneak up on us." Yuki told Flint, taking out her spear, she jumped down from the roof they were on, and pierced the Gastrea through. It was dead this time. She made sure she stayed on the spear. It was a Gastrea that could spit out poison/acid. It was more not a scorpion like she was, but it was an arachnid, most likely a spider. With it dead, Yuki took off part of the spear. Her spear was segmented and connected via chains. She held onto the end, while standing onto the rest of her spear. Jumping up from the spear, and with the momentum, pulling the spear with her, she landed back on the roof.
"I'm back." she said.
"Are they done yet?"
Seikou
The Gastrea didn't charge at him, it rammed into anything that was near it. Hearing Hitoshi say "It's probably half-dead. Ready to finish this?" Seikou could see Akane smiling, baring her teeth. She should stop licking her lips before her prey was what he thought, but knew it helped as a signal for himself. Calculating from what Akane's most likely point of action was, while she zig zagged, he believe she would jump to the wall she kicked the Gastrea into before and then launch herself to attack the Gastrea, and send it flying through the crates.
Walking around to the direction, where the Gastrea would most likely end up after Akane's attack, Seikou switched to Blade mode. He poised himself, and waited for the right moment. Hearing the impact, the Gastrea was being sent flying. He could hear it crashing through the crates, exoskeleton and flesh being ripped off it. 4, 3, 2, 1 he slashed, pulling the trigger, vibrating the blade at a super sonic frequency. It may have hurt Akane's ears a bit, if they did he would have to treat her to something again. The Gastrea, cleanly was cut into two pieces, splattered in two halves against the wall behind him. The acid did not affect him or his weapon. It did not touch him, but the weapon was resistant to it, at least for a moment. He flicked his varanium gunblade, making the acid fly off of it. The walls were started to melt from some of the splattered acid from inside the Gastrea.
Sensing for whether it was still alive, he could confirm it was dead. I guess Hitoshi didn't get to do anything this time, I wonder what happens to him. Seikou thought. Through the path of destroyed crates and pieces of flesh and exoskeleton, Seikou walked up to Akane and patted her. Turning to Hitoshi, "Good work." were the words he spoke as he turned to the door and started to walk out.
