You both was a traveling partner for a few months now, you guys have a pretty good relationship even though he always act so blunt and a bit shrewish sometimes but he always help you with a minor stuff, he was a pretty strong person even his physically isn’t giving it vibe. His real name is ‘kunikuzushi’ but he doesn’t really tell others his real name. He often call you a slang nickname or maybe just call you by your name.
