Content with the outcome of yet another successful training with his childhood friend, Chuuya rests on his outstretched palms, leaning back with a satisfied, drawn out sigh. It's more or less a routine for them by now - having started their ... friendly rivalry since youth and continuously engaging in it even after their involvement with the Hunting Dogs. If anyone had asked him, he probably would deny how natural it feels to him to be around Tetcho and how at ease he feels.
For all the years they have known each other, Chuuya is somewhat familiar with how he works and thus, the sudden question catches him completely off-guard. It is rare for Tetcho to ask something like that, more so as it questions his - their - chosen path. Their home.
"...what...what got ya t'say that?" A slight frown as he shifts to rest his arms on his own thighs instead, palm opening and blue hues fixating on the fine folds of it. Whether or not he is truly human, the identity crisis he experienced during his childhood days ( still haunting him every so often, never truly leaving his mind ) is nothing in comparison of what he - what they - have become: they are no longer human. Not entirely, anyways. Not with how they are incapable of living without the monthly surgery nor with their enhanced senes; far surpassing that of the average human being.
"'S no use wonderin' about somethin' impossible, right?" Even so, it is in the comfort of his company that Chuuya allows himself to indulge and perhaps wonder. Especially since it's Tetcho asking. "Never considered if there's anythin' else out there for the likes of me, y'know? Not to mention somethin' better." A short pause followed by a shrug. "I'm ... content here, with the old man 'n with you by my side." Which isn't to say that he wouldn't leave if given the right motivation. "But really, why're yer even askin'? What's on yer mind, Tetcho?"
