Tập 6: Luna thâm nhập phi hành đoàn trong khi Senku khám phá danh tính thật của Xeno là một nhà khoa học từng làm việc tại NASA.

As part of Xeno's plan to eliminate the Kingdom of Science's leader, Stanley sends a young woman named Luna to infiltrate the science crew and find Taiju so that he can kill him once she lures him out in the open. Ryusui becomes suspicious of her, believing that she's a spy. Senku on the other hand secretly plans to extract as much information from Luna as possible about Xeno and his crew, that way, he'll transmit the encrypted message to Tsukasa's special squad. Luna begins searching for Taiju, until she eventually finds him, but before she can attempt to give Stanley the signal, Senku appears and begins to charm her in an attempt to extract information from her about Xeno. He is suddenly interrupted by Ryusui and Francois as the former puts in a request to give her something desirable. Senku and Francois end up recreating ice cream for her to enjoy, much to her delight. In a surprising turn of events, Senku begins to realize who Dr. Xeno truly is and reveals that he is a former NASA scientist, as well as his old science mentor from his childhood who helped kickstart his passion of building advanced rockets for starters.
