While Boruto and the others are forced to participate in Ouga’s experiments, Sarada and her team investigate Boruto’s disappearance and discover the existence of a suspicious individual. 
Meanwhile, Boruto is shocked to discover the identity of someone who may be working for Ouga. Just then, a test subject is found dead—killed for reasons that have nothing to do with the experiment.

Mr. Namua! Didn't you tell me
you're no longer a villain?
ناموا-سان! ألم تخبرني أنك ما عدت شريرًا؟
Signor Namua!
Namua! Não me disse
que não é mais um vilão?
Намуа! Вы ведь сказали,
 что больше не злодей!
