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.

One of them killed those two.
.أحدهما قتلا ذلكما الاثنان
Einer von beiden muss sie getötet haben
und nun im Besitz von drei Karten sein.
Uno de ellos mató a esos dos
Uno de ellos ha matado a esos dos
Uno di loro due li ha uccisi
Um deles os matou.
Один из них и убил Батту с Фуго.
