Maru's gaze turned back to the Hyuuga, the boy seemingly was a little doubtful that the man could actually fight Maru without harming him. Unless the Hyuuga happened to had great counters and defensive techniques against the young shinobi, but then again the man was on a different level then him so he'll find out sure enough. “Heh. Well I guess with the proper guidance you might redirect that bloodlust to a more fun playmate. Seems fair.” Maru admitted, nodding his head feeling a bit excited in having his powers enhanced. With any luck, he'd be the strongest shinobi around with a cold personality which was something that interested him most.
He snickered in his heart when he uttered the same words she used during their research on poisons. Truth be told Maru didn't think that Mikasa would fall into his trap but her curiosity got the better of her. She must would've known that her words would have came back to haunt her at a later date, after all this method of finding out by experiencing the effects yourself did seem to be an effective tool so Maru thought. Allowing her to grab his hand he extended out to her, he looked up at her to watch her reaction. At first Mikasa didn't show signs of being affected by Maru's evil chakra, the boy thinking that the medical kunoichi possibility couldn't control his aura through her. But then Maru saw that her aura– that usually took on a teal color– turn crimson red. Taking whole of her entire body with a grin appearing on her face, and she gripped his hand rather tightly. Maru making a mental note of Mikasa’s behavior, wondering how she was feeling in using his chakra.
Maru saw Mikasa seemingly zoning out for a moment. She just got really silent, with a grim expression on her face that made Maru wonder what had she been thinking. But of course the experiment didn't last as long, with quick action she had been able to fight against Maru's demonic aura and it went right back to her normal teal color upon releasing his hand. The young shinobi wanted to ask Mikasa how she felt, but it would seem that she wanted to do this research on a later date. And that made Maru smile a bit "Alright fine.” Maru said picking up where he left off. “But I did notice that you had a weird grin and a strong grip that might have broken my hand.” the boy said, hoping that his mentor gotten a better understanding for her research.
With the final notes written up, Mikasa was a bit exhausted. The young shinobi leaning back for a bit “I'm looking forward to beating up on some clones of yours, I'll make sure me and my girls are ready for a fight with a Hyuuga.” Maru seemingly gloated, the Kawaii puppet of his still on his lap however he decided to put her in a weapons scroll that he made personally for his beloved puppet. Reaching inside of his weapons pouch, he pulled out a pink colored weapons scroll with a cute sticker of his beloved Kawaii puppet holding a peace sign with her mechanical fingers. Opening his designer scroll, his puppet was sucked into the scroll then Maru closed it. Putting it Kawaii's scroll in his weapon pouch. “Don't judge the artwork, I find this scroll fitting for Kawaii’s personality.” the academy student felt the need to explain the rather feminine scroll that a tough guy like him wouldn't be caught dead having. It was already strange enough that he used actual dolls to be his puppets, he honestly didn't know where the idea of making female puppets came from. Perhaps it was just one of those things that people just do one time and get addicted to doing. In Maru's case that thing was making dolls.
