Unevolving Species

Summary
As the mysterious man guides the weapons towards Sasuke, the latter easily deflects them with his sword before pointing it against the opponent, who catches it in order to let his son land a successful attack. However, Sasuke's Rinnegan lets him swap places with Shin, shooting a dense ball of fire to complete the counter-attack. The attack is deflected thanks to the enemy using Shin as a shield, though both of them get caught in the explosion. Noticing Sasuke's great ocular prowess, the enemy presents himself as Shin Uchiha, to which Sarada comments that he had the same name as his son. After telling Naruto to take care of the children, Sasuke goes on the offensive, but Shin manipulates the opponent's sword to attack Naruto, who ends up deactivating the cloak due to the injury. Since the cloak had blocked some weapons before, and with the cloak gone these weapons were free, Sasuke has to shield his daughter with his own body, which ends up being paralysed by said weapons. Sakura arrives in time to stop the two enemies, but their creature teleports the two of them – along with Sakura, who got caught up in the technique – to their base, where the father proceeds to transplant his injured son's liver in his own body to repair the damage caused by the kunoichi.
