Lonliness, as always, was a common thing for the blonde as he lived by his own in the apartment. As he didn't know anyone that closely, no one came to visit him not even once.
But he had company. The Tsuchikage, and believe it or not - his mouths. The blonde often sat down to speak to them. It may sounded like he was going mad but that was the only thing he could do to build a relation with them. Talk, teach and pride. It was like he had created a whole colony in his own house! He acted childish, but since no one came to take care of him and teach him to act for his age, there was nothing to complain about. No one wanted to take care of him either, because they thought Deidara was old enough to live on his own. A thirteen year old.
It took several days to tame the mouths. The palm ones was easier, but the big one on his chest was a bit more dominant.
Even if Deidara didn't rip the stitches off, he felt how greedy it was. If the mouths didn't listen, Deidara would sew them shut or hit them against something solid and hard. Then they would not open for half an hour, until they slowly got a bit courageous up again. The biggest one again was a lost case for Deidara. He was too soft against it.
It took three weeks to tame the hand mouths well enough to use them for ninja work. He let them eat, instead of eating himself through his main mouth on the face. It didn't taste anything then, but he got stuffed enough. And they reacted to his mood, too.
When Deidara was happy, the mouths listened well to him. When he was tired they got tired too. When he was depressed they didn't do anything to annoy.
The blonde had practised at home too, to give chakra to other things through the mouths.
The thing was to not let them swallow the fruit, paper, or anything like that. They would just fill the fibers or cells in the thing that was put into them and then spit it out again - finished. But now step two in the progress had to work too.
Ohnoki had taken the book with the forbidden jutsus for himself, and was ready to seal it away when the blonde had finished his training. He had told that the next thing was to release an explosion.
Since the blonde was the only known wielder along with Gari to carry on the Explosion release, he wanted to be good at it. The famous ninja Deidara of the Hidden Rock!
However, this step was way harder to perform. He had to twist and spin chakra, then just let it go.. It was harder than he expected it to be.
Days, nights, weeks, weeks and weeks passed on. At month three of the training, Deidara had succeeded to perform small explosions with donation clay. He usually carried a green belt with two bags on each hip to easily access it with his hands. But then again, these were small. The explosions wasn't big enough to kill somebody, maybe damage a tiny bit. He had told his master, Ohnoki, that he wanted to go bigger.
Four more tough months passed on, and Deidara had learned how to create clay clones, C1 and Explosive Landmines. Not only that, he worked to create even more art on his on free will.
The birds he once adored that could fly, the art of explosions. The blonde knew he could take it to any higher level if he wanted.
That way of ninja was the only thing that mattered nowadays. The Tsuchikage's granddaughter, Kurotsuchi, often entered the training grounds to train too. But she often sat down to watch Deidara. His long hair danced in the air as he jumped around. He looked so happy when he set the sculptures off to explode.
There was often arguments about it. She would often laugh and complain about the sculptures, of how obsessed Deidara had gotten. He would then scream ugly words back at the younger kunoichi to defend his precious art. But of course they also had nice moments togehter, and Deidara felt like he wasn't alone anymore.
As the Tsuchikage had looked over the younger blonde, he could soon exclude that the Genin was good enough to join the Explosion Corps.
