It must be Uchihiro Shoko Asahara's younger brother Quannai. Because the person who shocked the masked man is probably four generations of Huo Ying Namikaze Minato. Think about it, Ban confronts the first generation of Huo Ying, Ban can't fake his death, and the first generation of Huo Ying can't be wrong. Like his younger brother, Ben has an eternal kaleidoscope. Now that Diandian is dead, Dou may find Diandian's body. Compared with the four generations of Huo Yingbo Feng Shui Gate, I think the spot is better. First of all, apart from flying Raytheon, Namikaze Minato may also know how to seal, and he has no extraordinary skills. Compared with Namikaze Minato, there is an eternal kaleidoscope sharingan, and you can also use SUSANOO. Therefore, the only thing that shocked the masked man was the scene. So who is the masked man? It can't be dirt, it can't be kakashi, and it can't be a skunk. So who else is the powerful ninja who inherited Uchibo's lineage? Of course, there is Quannai, so maybe Quannai is not dead (as Quannai, of course, don't make trouble when you are dead ~). Attention, everyone. In the first picture on page 7 of sentence 398 of Huo Ying, there is a man with sharingan on his forehead, which may be Quan Nai. You can also notice that the masked man's forehead is covered with white cloth, which may be San sharingan's people.
Having said so much, it is enough to show that the masked man is the younger brother of Spot.
