So that was the kind of level he was trained to fight. The thought was terrifying: crossing swords with a shinobi capable of impaling his opponent by growing a set of bone weapons from his body. How could his kenjutsu be ever high enough for that? He had been gifted with a hiden too, unlike the majority of his comrades, but he'd need to find a way to make it useful in such close range. He wondered if it was it painful for Kogane, to grow them each time anew. "That's impressive." He said with sincere admiration, eyes fixed on the pearl white bones. 

He would gladly show his own techniques in return, but his chakra control was low, shameful. Izumi was younger than him and already looked like a powerful Nara, while he was just a random clan member easily mistakable for an adopted child who had nothing to do with the genius they were known for. He just hoped Kogane wouldn't take it badly.

Now all he had to do was hit a few times while avoiding those spikes, including them in the scheme of attacks. That was what he'd have to do all the time after all for a movement to work smoothly: with all the variables in a fight, react and adapt to them and still lead the blade where it should be. Taking a fighting stance again, he repeated the movements, quickly changing position and giving short, quick strikes that used the sword's speed rather than its sheer force.

*"Not really, my father was truly impressive. He could make castles of bone during his days as Shinobi. His abilities were truly respectable."* Yes, his father was the prodigy, not himself. While he wished he had his father's skill in Shikotsumyaku, he was rather glad he could start from the bottom, and climb his way up. Why would someone want to be perfect at everything? That was so boring, and having weaknesses in combat that your opponents could exploit was one of the best parts about shinobi combat.

Kogane isn't very judgmental, and because of his upbringing and ancestry, he has learned to never judge some by their looks or their surroundings. He didn't expect he newly made friend to flaunt his skills, the Kaguya himself only demonstrated his because the Nara presumably wanted to see for himself. Kogane exhaled briefly, before retracting each bone that had grew prior, back into his body. Afterwards, he would start re-growing the thick bone pads from his fingers, trying to get better at it.

He then waited as Toshizo started attacking again, and just like that Kogane was on the defense once more. He took each attack, although he was relying on his innate armor technique like he was earlier. He took each blow hit for hit, attempting to better his stamina and pain tolerance, as the ends of the blade slammed against his skin.

His father, uh? Typical of clan members to have strong shinobi to look up to and brag about. Bone castles... His father was a farmer, his most precious heritage a set of wooden birds he crafted himself and that they kept in a corner of their house in Iwaki, like an altar. He didn't even remember him, as he was four when the plague took him away. His mother, he had no clue what she was capable of since she retired before he was born and never showed him. Toshizo didn't feel shame for this, just a deep discomfort around these people; a part of it was surely envy, though he'd never admit it.

"I think that's enough for today. I'm not enjoying hitting you like this, but I feel that asking for a fair fight would make me regret it." Drops of sweat covered his forehead despite the cold weather, and his arms were starting to feel heavy. A katana could look gracious and light, but its length required a little strength to wave it accurately. 

Sheathing it with care, he walked towards the boy, bowing to thank him for the training and for letting him use him as human target. He had a little money in his purse, a perk for belonging to a clan though he planned on living off his own earnings soon "I was thinking of eating something at the bistro. It's.. One of the few places I can find easily. You want to join me?" A part of him wanted to be rejected, but for once he could go home and tell Izumi he did well and made a friend. She'd be over the moon.

*"I would love to join you."* His expression would go soft as his stomach growled, with bruises covering his body he felt like he needed some food. He nodded, and grabbed his robe before standing next to the Nara. *"Shall we go..?"* He pulled the hardened bone pads that were over his fingers back into his hands, as the two walked and went towards the Bistro, for some MEAT.
