Filled with excitement, Ukai rushed towards the stadium, having been told from the camp that they had something they could try to get Nishinoya human again. Everyone would be getting back from their camps by now, so he planned to tell the news then. He thought about visiting the dog before he went in, but, it was for now just a dog, so he walked into Karasuno's volleyball court staduim. As soon as he saw the sence, hus heart raced.
The dog (Nishinoya) was on top of Asahi, who was on his back on the ground, jumping and barking.
Ukai dashed towards them to yank the dog off, when he realized Asahi wasn't resisting, but laughing with happiness and relief.
"Oi, coach!" Asahi looked over, sitting up as Nishinoya proceeded to run around him and jump on his shoulders, more excited than ever to see his best friend again.
Nishinoya then looked at Ukai, who realized his eyes were different and he wasn't being aggressive anymore.
"Is he..." The coach stared blankly at him.
"He seems to be completely back" Asahi said. "Minus the dog body"
Then, the stadium's doors opened to reveal Karasuno's entire team that walked in and then stared at the unleashed, unmuzzled, free dog.
"Hey! he's- " Sugawara only got a quarter of his words out before Nishinoya ran towards them all, dashing around each of them and jumping on a few.
Nishinoya's memories seemed to have a huge gap in them the moment he got transformed, so in his mind he hadn't seen then all in weeks.
The team noticed "the dog" was different in many ways, and realized their Libro was back.
time goes by*
The Libro training camp successfully turned Nishinoya back into human, surprisingly without any flaws. Since Nishinoya's parents were luckily out during thise few days, only the players of Karasuno know about the bizarre tale of the Libro that literally got turned into a dog.
