A latenight encounter (R18)

Deep into the night after the busy day.

Yuri was tinkering on something with rapt attention. These days, she was all but free. Too many things to research and only twenty four hours in a day—she wished she could create a way to reduce sleep. 

She rubbed her head. "Thankfully, the Hunter Awakening was successful, at least." Then, she looked at Mark, who was looking at her with rapt interest. "So, why did you go so far to ruin those cheap kids' reputation?"

Mark asked, "What? I can't have some hobbies I like to do for no reason?"

"Surely, you can." Yuri put aside her goggles and turned off the lights on the lab table. She walked towards the demon and sat down on the couch beside him. Dona looked at her from the other side of his shoulders. "But as far as I saw, you are not the type to do something for no reason."
