"H-Huh, oh, yes..." Oh... was Rena perhaps pulled in by the boy's aura or something? Was she somehow trying to protect the boy with her comment about him being diplomatic? Noboyuki was needlessly defensive when in front of this boy, and since it was also regarding Rena, well, Noboyuki was being a bit too defensive. He stopped at the same time Rena did, and turned back to look at the boy, but even so, he didn't move from his place. He may have taken the 'just give me a moment' part of what Rena said a bit too seriously too. He posed his sharp eyes over the boy. As a, by now, seasoned warrior, Noboyuki knew he himself had some amount of intimidation skills when facing against the unknown. He glared at the boy sharply and letting quite some killing intent sip out of his body.
And then, the boy Ryuma, answered with a sharp galre of his own, as well as letting some of his killing intent become known. Yeah, it was way bigger than Noboyuki's. With his two months of training and battling, he knew when he was overpowered, and he was HUGELY overpowered here, so much he even had to take a step back out of fear. Ryuma was about as intimidating to him as the God they encountered in the forest. He was certainly strong. The boy, hoping Rena didn't catch on on that and looking pretty nervous again, started fidgeting around. "Y-Yes, I hail from, um, whatsitsname...." He mumbled under his breath. "Ah yes, that place! N-Nijiara?" Noboyuki caught up on what he was trying to say almost immedietly, and knew why Rena was suspicious as well. That 'Nijiara' he was talking about sounded an awful lot as how Japan was named in Japanese, Nihon.
And since the boy seemed to know he had screwed up as well, he heaved a heavy sigh and, for the lack of a better word, facepalmed. "Ugh, fine! All right, fine! I've also been summoned here from another world! The same that old man came from!" Ryuma merely motioned with his head towards Noboyuki, who passed from scared to angry in an instant.
"What do you mean old man brat!" As said before, the boy didn't really strike up Noboyuki as someone he could get along with. "And why the hell are you here too! I should've been the only one summoned here! Do you know what's going on Rena?" Noboyuki lashed out, but as soon as he turned to Rena, he calmed down. "I'm... sorry. I just lost my cool there." Yeah, not the best side of him Rena could be seeing right now.
"Just let me in in your adventure! You won't be able to kill the Demon Lord without me! I am kinda, like, the tank and magician companion you get in an RPG, yeah? Just, c'mon! I'm gonna be extra useful! Besides, how can I get a lady like this alone with a creep like you?" The boy said, taking Rena's hand and kissing it. Yes, the worst kind of guy. Hardheaded, stupid and a flirt. Just precious.
Noboyuki quickly moved in and made Ryuma let go of Rena's hand. "No touching allowed please."
"You jelly boy?"
"I'm gonna cut you up, you little....!" He was about to take out his sword, but took a deep breath and calmed down. He should really let Rena handle it. He turned around and decided to wait just behind the two of them to finish up talking.
