In Chapter 51 of Boruto: Naruto the next generations "Sacrifice", published on MangaPlus, continues the conflict between Sasuke and Isshiki Otsutsuki. Boruto's intervention saved Sasuke's life, and the young ninja realized that Isshiki doesn't want to kill him. The alien wants to use Boruto for his plan.
In Boruto 50, the clash between Isshiki and Sasuke began, in which our exhausted ninja was saved by the intervention of young Boruto. We find that Isshiki's plan is to create a divine tree to cultivate the fruits of the chakra. Amado will reveal to Shikamaru that a ten-tail is needed to create a divine tree, and that ten-tail must eat a live otsutsuki.
Amado continues his explanation by saying that the Otsutsuki always invade a planet in pairs, one of the two will be the sacrifice for the Ten Tails and the other will watch over the divine tree until the fruits of the chakra are born.
Thanks to Sumire, we discover that Isshiki's plan is to sacrifice Boruto in his place and feed him to the ten tails. The title of the chapter "Victims" most likely refers to theIsshiki's intention to use Boruto as a sacrifice for the Ten-Tails. Despite Sasuke's attempt to defend Boruto, the boy is injured by Isshiki.
Naruto will come to save his son, ready to risk his life to defeat the alien and save the earth. After a dialogue between the Hokage and Kurama, the nine-tailed fox gives him new strength, but if Naruto fails, he will lose his life.
