Is Namikaze Minato dead or not? !

Namikaze Minato died while sealing Kyubi no Youko!

It seems that LZ is an anime party!

You said that the four generations appeared because when the four generations sealed Kyubi no Youko, they sealed part of themselves and their wife chakra in Naruto's body, so that part of their consciousness remained in Naruto's body, so that they could come out to help Naruto when Kyubi no Youko was out of control, but only once. After all, the number of sealed chakra is limited, so the four generations only rely on this tiny part of chakra to appear in Naruto's consciousness!

In the spoiler, Naruto's mother will also appear in Naruto's consciousness in the future plot to help Naruto!
