Chapter 1 of Sasuke Retsuden: The Uchiha Descendants and the Heavenly Stardust (manga).
Summary[]
Sasuke and the rest of prisoners witnessed how Menō ate the escaped prisoner. Some prisoners started wondering how Zansul could control the beast but they were quickly told to go back to work by Zansul himself. Just as Sasuke began his work, one of the prisoners approached him. Sasuke didn't know who he was, but the prisoner introduced himself as Jiji, one of Sasuke's cellmates. Jiji wasn't very focused on his task, only using his pick when the guards are around and complaining about the cold temperatures. He revealed that they were working to build a base for a telescope. To his luck, Jiji injured his hand and said that this would allow him to visit the infirmary again. Sasuke asked why that was a positive thing, to which Jiji explained that the prison had a new sweet and beautiful doctor who happened to be single. Sasuke asked how he knew she was sigle and Jiji answered that its a custom to wear a wedding ring in the left hand, a local tradition that Sasuke isn't familiar with. He recalled Kail's ring.
At night, Sasuke's cellmates invited him to play Cee-lo with Penzila. Sasuke initially refused, but then he agreed and created a gem to use as a wager. Penzila decided to use his cigarettes as his wager, but Sasuke told him that he would do him a favor instead. In order to win the game, Sasuke manipulated the dice with Wind Release to achieve the desired number. Penzila was sure that Sasuke had cheated, but Jiji convinced him to admit his defeat. As his favor, Sasuke asked Penzila to cover him up while he leaves the cell. However, Penzila clung to Sasuke and pleaded him to not leave or he would be killed, and Gigi added that Sasuke needed a cloth pass to leave the cell.
Sasuke left the cell to find Menō, which he suspected is a summon controlled by Zansul. Sasuke wondered how Zansul would be able to keep a summon for such a long time, a feat that would only be possible if Zansul had great reserves of chakra. On his way to find the creature, Menō found Sasuke first. Sasuke tried to put it under genjutsu, but Menō is unaffected and launched an attack. Confused by this, Sasuke used taijutsu to take it down, but after seeing that the creature was up once again, he decided to escape to avoid leaving any evidence of a fight, but Menō is too fast for Sasuke to outrun. Using Ice Release, Sasuke created a kunai and cut Menō's claws to force it to retreat. Sasuke realized that the act might have consequences.
The next day, Sasuke saw from the dining room that Menō had its claws back. He was confronted by Zansul and indicated that he was aware of the fight that had taken place. As a cover for his mistake, Sasuke tried to put Zansul under genjutsu to interrogate him but was also unaffected. Closing the distance, Zansul took off his glasses to reveal that he had a glass eye. He complimented Sasuke for his shinobi skills and told him that he would never take the control of Menō from him. Then he warned Sasuke that he would keep a closer eye on him.
