What is the relationship between Lumineer, Lumineer, Zero, and Boss in the Dragons. Be detailed.

This has to be determined from Dragon clan 3 prequel, Dragon clan 3 down, and Dragon clan 5. From the prequel, Zero's character and ability is Lumineer, from Dragon 3 Down Zero's looks are the same as Lumineer's (conversation with Herzog), the boss is Zero (Sake De Mamoru can't tell if he's Lumineer or the boss from his appearance), and the boss is in a vision every time he appears in front of Sake De Mamoru and Chips, (as pointed out by Dragon 5), which is the same as Zero (Zero and Renata) The Dance of the End Times on Christmas Eve was also in a vision, as Zero ended up in a pile of golden powder, with his body remaining in Zero's room). Zero is having brain bridge surgery would be affected by the sound of the clapper, and Luminaire did the same in Dragon 3 and Dragon 5. So Zero's body is definitely Lu Mingfei no doubt, but his personality and psychology is Lu Mingze. If we follow this logic, these 4 people are one in a sense, and it's okay to say they're the same person
