Yuki was skipping backwards as she heard Flint explain that he could always get better. 
"Hai~" She replied as he told her not to throw the javelin. She replaced it back into her backpack.
"I believe you need more practice on moving targets in the first place, and predicting movements, or helping co-ordination." She criticized him.
"You need to think about how you target the enemy. Do you go for the kill? Or do you guide them and act as support? Using the shots to make the enemy dodge in a particular way. You've been hitting them only because I have been paralyzing them or pushing them into clear shooting conditions. Sure this works for now, since we have only dealt with only one Gastrea at a time, but it would help if you can shoot them yourself or guide them to me in cases of multiple infestations." She continued. Yuki was lecturing Flint on his performance, as they finally reached the front of the Nomura Security Corporation HQ. She was rather talented as a combatant and despite being young and childish, she grew up learning tactics and strategies.

There were a line of PMCs outside the building. Yuki straightened up, she was unfamiliar with them. She attempted to appear as normal and proper as possible in front of unfamiliar adults. Once inside, she returned to her skipping and energetic self. She was known to many of the people inside of the HQ, and she got along with quite a few. She plays tricks on them too. Since they know about her, she plays some more elaborate tricks, like paralyzing and drawing all over them. Some of them do look at her in disgust, but she was fine with that. Eventually she will be friends with them she believes. 

Yuki approached the door to the section they belonged to. Opening the doors, "Oha Kiri! I brought along Flint!", full of energy, she called out to the president of Nomura Security Corporation, Kiri Nomura. Yuki jumped into Kiri giving her a hug. It had been a while since they last met, or at least it felt like it to Yuki. About a week. "What's going on today that you called us in for?" She asked, looking up at Kiri.
