Undertale Yellow x Reader oneshots and stuff

The work waits (Chujin x Male!Reader)

This is a request by Daraconicus and I immediately had to jump on it when it came in. 

More like when I saw it an hour later but ANYWAY. 

This one might get a bit heavy so be careful. 

Description for what you look like (This is important!!!): You're kind of made of gelatin, like a moldsmal yet taken more of a monster like shape. That shape can look like anything you want, you do have arms and hands, maybe a snail like foot to move around if you so choose? You also have a face that can look however you want. 

General warnings: Fluff, angst, a bit of psychological stuff.

"You know, you're a genius," you and your best friend, Chujin, were seated in his office in the Steamworks. He had brought you here to discuss something. He didn't disclose what it was, he only said he couldn't trust anyone else with the information he was about to disclose to you. 

"Heh, many have said so," he responded and pushed his glasses back up the bridge of his nose. You know he's been praised for his inventions by nearly everyone he's met. He only really reacts to it when you or Ceroba deal it to him, though. You suppose it means more to him when it comes from someone he's close to than someone he's just met. 

He had brought up the idea many months ago. 

The idea of implanting a human soul into a monster. But back then, it was only an idea. 

Now. 

Now, there are plans. There are hypothesis, details and blueprints, pages and pages and pages of hastily scribbled notes strewn haphazardly across the table you two had met at. 

A robot. A prototype, meant to harvest human souls for the greater good of monster kind. To use their soul for... unmentionable things. He knew, you knew, there would never be a patent put in place for something like this. 

There's no harm in trying though. 

Right? 

"I know what happened with Kanako and her friend was jarring, but..." You hesitated, placing a hand to your chin and feeling your face mold into your palm. "Is... Is killing every human it comes across truly necessary?" You slowly asked, gauging his reaction. He seemed to contemplate your question before he looked at you with an unreadable gaze. 

"(Y/N)." His voice was stern, a tone you've only heard from him when he's entirely set his mind on something. 

"I know you aren't in my shoes. I know you haven't experienced the pain of losing a child. That's why I'm trying to explain. Humans. Are. Dangerous," he annunciated every word sharply, lightly slamming his palm on the table to prove his point. "If there is anything we- I can do to protect the Underground, then do it I must." His clawed hand dug into the metal of the table. You watched his paw clench and unclench, almost as if grasping for something. His hopes, maybe. 

"We, I, have a human soul in my possession," he leaned in and nearly whispered. You almost didn't hear him. 

"You... What?" You silently gasped, feeling your hands start to tremble. 

"If I can-" He interrupted his own sentence to breathe, you noticed his breathing had become quite shallow and panicked. When he spoke of his work he was often easy to excite. You knew the signs of an enthusiastic Chujin sometimes even before Ceroba was able to recognize it. "If I can inject it into a monster as they are about to dust I can- they can be saved. They could live. Imagine what a world we could live in if monsters could live forever."
