The real identity of the masked punk may be Uchiha Kagami. A Fei knows the details of Muye Village like the back of his hand, which shows that this person has many experiences and stories. The murder of Neiguang family was planned by four top cabinets of Sarutobi Hiruzen, Shimura Danzou, Mitokado Homura and Utatane Koharu. And teddy boy actually knows the inside story, which means that this person may have a very high position. These people were colleagues when they were young. Later, Sarutobi Hiruzen became three generations of wooden fire babies, and Mitokado Homura and Utatane Koharu became consultants. Sarutobi Hiruzen was 69 when he died, and Shimura Danzou was 72 when he was assassinated. Uchiha Kagami was about 70 years old at that time. Judging from the half face when Teddy boy took off his mask against Hoshigaki Kisame and the eyes and forehead exposed on the broken mask when confronting Peony, Teddy boy is already an old man. So it's very possible: A Fei is Uchiha Kagami who was pushed out to find another way out. A Fei has always called himself Uchihiro Madara, but Uchihiro Madara's age should be between 85 and 95. Besides, the real Uchihiro Madara has been summoned to fight Gokage and reincarnate with filth. Therefore, A Fei won't be the real Uchibo Madara. In terms of age and status, Uchiha Kagami is probably the son, nephew or brother of Uchihiro Madara.
